    Your Questions Answered on NVDIMM

    May 23rd, 2016

    The recent NVDIMM webcasts on the SNIA BrightTALK Channel sparked many questions from the almost 1,000 viewers who have watched it live or downloaded the on-demand cast. Now,  NVDIMM SIG Chairs Arthurnvdimm blog Sainio and Jeff Chang answer 35 of them in this blog.  Did you miss the live broadcasts? No worries, you can view NVDIMM and other webcasts on the SNIA webcast channel https://www.brighttalk.com/channel/663/snia-webcasts.

    FUTURES QUESTIONS

    What timeframe do you see server hardware, OS, and applications readily adopting/supporting/recognizing NVDIMMs?

    DDR4 server and storage platforms are ready now. There are many off-the shelf server and/or storage motherboards that support NVDIMM-N.

    Linux version 4.2 and beyond has native support for NVDIMMs. All the necessary drivers are supported in the OS.

    NVDIMM adoption is in progress now.

    Technical Preview 5 of Windows Server 2016 has NVDIMM-N support
     

    How, if at all, does the positioning of NVDIMM-F change after the eventual introduction of new NVM technologies?

    If 3DXP is successful it will likely to have a big impact on NVDIMM-F. 3DXP could be seen as an advanced version of a NVDIMM-F product. It sits directly on the DDR4 bus and is byte addressable.

    NVDIMM-F products have the challenge of making them BYTE ADDRESSBLE, depending on what kind of persistent media is used.

    If NAND flash is used, it would take a lot of techniques and resources to make such a product BYTE ADDRESSABLE.

    On the other hand, if the new NVM technologies bring out persistent media that are BYTE ADDRESSABLE then the NVDIMM-F could easily use them for their backend.
    How does NVDIMM-N compare to Intel’s 3DXPoint technology?

    At this point there is limited technical information available on 3DXP devices.

    When the specifications become available the NVDIMM SIG can create a comparison table.

    NVDIMM-N products are available now. 3DXP-based products are planned for 2017, 2018. Theoretically 3DXP devices could be used on NVDIMM-N type modules

     

     

     

    PERFORMANCE AND ENDURANCE QUESTIONS

    What are the NVDIMM performance and endurance requirements?

    NVDIMM-N is no different from a RDIMM under normal operating conditions. The endurance of the Flash or NVM technology used on the NVDIMM-N is not a critical factor since it is only used for backup.

    NVDIMM-F would depend on various factors: (1) is the backend going to be NAND Flash or some other entity? (2) What kind of access pattern is going to be done by the application? The performance must be at least same as that of NVDIMM-N.

    Are there endurance requirements for NVDIMM-F? Won’t the flash wear out quickly when used as memory?

    Yes, the aspect of Flash being used as a RANDOM access device with MEMORY access characteristics would definitely have an impact on the endurance.
    NVDIMM-F – Doesn’t the performance limitations of the NAND vs. DRAM effect the application?

    NAND Flash would never hit the performance requirements of the DRAM when seen as an entity to entity comparison. But, in the whole perspective of a wider solution, the data path of DRAM data -> Persistence Data in a traditional model would have more delays contributed by a good number of software layers involved in making the data persistent versus, in the NVDIMM-F the data that is instantly persistent — for just a short term additional latency.
    Is there extra heat being generated….does it need any other cooling (NVDIMM-F, NVDIMM-N)

    No
    In general, our testing of NVDIMM-F vs PCIe based SSDs has not shown the expected value of NVDIMMs.  The PCIe based NVMe storage still outperforms the NVDIMMs.

    TBD
    What is the amount of overhead that NVDIMMs are adding on CPUs?

    None at normal operation
    What can you say about the time required typically to charge the supercaps?  Is the application aware of that status before charge is complete?

    Approximately two minutes depending on the density of the NVDIMM and the vendor.

    The NVDIMM will not be ready because the charging status and in turn the system BIOS will wait; until it times out if the NVDIMM is not functioning.

    USE QUESTIONS

    What will happen if a system crashes then comes back before the NVDIMM finishes backup? How the OS know what to continue as the state in the register/L1/L2/L3 cache is already lost?

    When system comes back up, it will check if there is valid data backed up in the NVDIMM. If yes, backed up data will be restored first before the BIOS sets up the system.

    The OS can’t depend on the contents of the L1/L2/L3 cache. Applications must do I/O fencing, use commit points, etc. to guarantee data consistency.

    Power supply should be able to hold power for at least 1ms after the warning of AC power loss.

    Is there garbage collection on NVDIMMs?

    This depends on individual vendors. NVDIMM-N may have overprovisioning and wear levering management for the NAND Flash.

    Garbage collection really only makes sense for NVDIMM-F.
    How is byte addressing enabled for NAND storage?

    By default, the NAND storage can be addressed only through the BLOCK mode addressing. If BYTE addressability is desired, then the DDR memory at the front must provide sophisticated CACHING TECHNIQUES to trick the Host Memory Controller in to thinking that it is actually accessing a larger capacity DDR memory.
    Is the restore command issued over the I2C bus?  Is that also known as the SMBus?

    Yes, Yes
    Could NVDIMM-F products be used as both storage and memory within the same server?

    NVDIMM-F is by definition only block storage. NVDIMM-P is both (block) storage and memory.

     

    COMPATIBILITY QUESTIONS

     

    Is NVDIMM-N support built into the OS or do the NVDIMM vendors need to provide drivers? What OS’s (Windows version, Linux kernel version) have support?

    In Linux, right from 4.2 version of the Kernel, the generic NVDIMM-N support is available.

    All the necessary drivers are provided in the OS itself.

    Regarding the Linux distributions, only Fedora and Ubuntu have upgraded themselves to the 4.x kernel.

    The crucial aspect is, the BIOS/MRC support needed for the vendor specific NVDIMM-N to get exposed to the Host OS.

    MS Windows has OS support – need to download.
    What OS support is available for NVDIMM-F? I’m assuming some sort of drivers is required.

    Diablo has said they worked the BIOS vendors to enable their Memory1 product. We need to check with them.

    For other NVDIMM-F vendors they would likely require drivers.

    As of now no native OS support is available.
    Will NVDIMMs work with typical Intel servers that are 2-3 years old?   What are the hardware requirements?

    The depends on the CPU. For Haswell, Grantley, Broadwell, and Purley the NVDIMM-N are and/or will be supported

    The hardware requires that the CPLD, SAVE, and ADR signals are present

    Is RDMA compatible with NVDIMM-F or NVDIMM-N?

    The RDMA (Remote Direct Memory Access) is not available by default for NVDIMM-N and NVDIMM-F.

    A software layer/extension needs to be written to accommodate that. Works are in progress by the PMEM committee (www.pmem.io) to make the RDMA feature available transparently for the applications in the future.

    SNIA Reference: http://www.snia.org/sites/default/files/SDC15_presentations/persistant_mem/ChetDouglas_RDMA_with_PM.pdf
    What’s the highest capacity that an NVDIMM-N can support?

    Currently 8GB and 16GB but this depends on individual vendor’s roadmaps.

     

    COST QUESTIONS

    What is the NVDIMM cost going to look like compared to other flash type storage options?

    This relates directly to what types and quantizes of Flash, DRAM, controllers and other components are used for each type.

     

    MISCELLANEOUS QUESTIONS

    How many vendors offer NVDIMM products?

    AgigA Tech, Diablo, Hynix, Micron, Netlist, PNY, SMART, and Viking Technology are among the vendors offering NVDIMM products today.

     

    Is encryption on the NVDIMM handled by the controller on the NVDIMM or the OS?

    Encryption on the NVDIMM is under discussion at JEDEC. There has been no standard encryption method adopted yet.

    If the OS encrypts data in memory the contents of the NVDIMM backup would be encrypted eliminating the need for the NVDIMM to perform encryption. Although because of the performance penalty of OS encryption, NVDIMM encryption is being considered by NVDIMM vendors.
    Are memory operations what is known as DAX?

    DAX means Direct Access and is the optimization used in the modern file systems – particularly EXT4 – to eliminate the Kernel Cache for holding the write data. With no intermediate cache buffers, the write operations go directly to the media. This makes the writes persistent as soon as they are committed.

    Can you give some practical examples of where you would use NVDIMM-N, -F, and –P?

    NVDIMM-N: load/store byte access for journaling, tiering, caching, write buffering and metadata storage

    NVDIMM-F: block access for in-memory database (moving NAND to the memory channel eliminates traditional HDD/SSD SAS/PCIe link transfer, driver, and software overhead)

    NVDIMM-P: can be used either NVDIMM-N or –F applications
    Are reads and writes all the same latency for NVDIMM-F?

    The answer depends on what kind of persistent layer is used.   If it is the NAND flash, then the random writes would have higher latencies when compared to the reads. If the 3D XPoint kind of persistent layer is used, it might not be that big of a difference.

     

    I have interest in the NVDIMMs being used as a replacement for SSD and concerns about clearing cache (including credentials) stored as data moves from NVM to PM on an end user device

    The NVDIMM-N uses serialization and fencing with Intel instructions to guarantee data is in the NVDIMM before a power failure and ADR.

     

    I am interested in how many banks of NVDIMMs can be added to create a very large SSD replacement in a server storage environment.

    NVDIMMs are added to a system in memory module slots. The current maximum density is 16GB or 32GB. Server motherboards may have 16 or 24 slots. If 8 of these slots have 16GB NVDIMMs that should be like a 96GB SSD.
    What are the environmental requirements for NVDIMMs (power, cooling, etc.)?

    There are some components on NVDIMMs that have a lower operating temperature than RDIMMs like flash and FPGA devices. Refer to each vendor’s data sheet for more information. Backup Energy Sources based on ultracapacitors require health monitoring and a controlled thermal environment to ensure an extended product life.
    How about data-at-rest protection management? Is the data in NVDIMM protected/encrypted? Complying with TCG and FIPS seems very challenging. What are the plans to align with these?

    As of today, encryption has not been standardized by JEDEC. It is currently up to each NVDIMM vendor whether or not to provide encryption..

     

    Could you explain the relationship between the NVDIMM and the IO stack?

    In the PMEM mode, the Kernel presents the NVDIMM as a reserved memory, directly accessible by the Host Memory Controller.

    In the Block Mode, the Kernel driver presents the NVDIMM as a block device to the IO Block Layer.
    With NVDIMMs the data can be in memory or storage. How is the data fragmentation managed?

    The NVDIMM-N is managed as regular memory. The same memory allocation fragmentation issues and handling apply. The NVDIMM-F behaves like an SSD. Fragmentation issues on an NVDIMM-F are handled like an SSD with garbage collection algorithms.

     

    Is there a plan to support PI type data protection for NVDIMM data? If not, achieving E2E data protection cannot be attained.

    As of today, encryption has not been standardized by JEDEC. It is currently up to each NVDIMM vendor whether or not to provide encryption.

     

    Since NVDIMM is still slower than DRAM so we still need DRAM in the system? We cannot get rid of DRAM yet?

    With NVDIMM-N DRAM is still being used. NVDIMM-N operates at the speed of standard RDIMM

    With NVDIMM-F modules, DRAM memory modules are still needed in the system.

    With NVDIMM-P modules, DRAM memory modules are still needed in the system.
    Can you use NVMe over ethernet?

    NVMe over Fabrics is under discussion within SNIA http://www.snia.org/sites/default/files/SDC15_presentations/networking/WaelNoureddine_Implementing_%20NVMe_revision.pdf

    SNIA’s Solid State Storage Initiative Advances the Industry at Flash Memory Summit

    August 28th, 2015

    A classic case of SNIA Solid State Storage Initiative (SSSI) member collaboration for industry advancement was on display in the SSSI booth for NVDIMM-N demonstration at the Flash Memory Summit (FMS) 2015. Under the direction of SSSI Chair Jim Ryan and coordinated by NVDIMM SIG co chairs Arthur Sainio and Jeff Chang and TechDev Committee chair Eden Kim, the SSSI was able to update and include NVDIMM-N storage performance in the SSSI marketing collaterals on the Summary Performance Comparison by Storage Class charts.

    2015SummaryPerformanceChart.NVDIMM.1200

    Five SSSI member companies – AgigA Tech, Calypso, Micron, SMART Modular, and Viking Technology – collaborated over a four week period on the introduction of a new NVDIMM-N storage performance demonstration. While it is rare to have potential competitors collaborate in such a fashion, NVDIMM-N storage represents a new paradigm for super fast, low latency, high IO/watt storage solutions. The NVDIMM-SIG has taken a leadership position by evangelizing the technology and developing the industry infrastructure necessary for large scale deployment.

    This collaboration highlighted a classic blend of technical, marketing and industry association cooperation.

    In the weeks leading up to FMS, the NVDIMM-SIG planned for an in-booth demonstration of the NVDIMM-N storage modules. To pave the way for universal adoption, the team worked together to dial in the Intel Open Source block IO development driver to meet the standards of the SNIA Performance Test Specification (PTS). An added goal was inclusion of NVDIMM-N modules as a new line item on the Summary Performance Comparison by Storage Class chart which lists PTS performance for various storage technologies. Under the guidance of NVDIMM-SIG, a rush project was instigated to get NVDIMM-N performance data tested to the PTS for the trade show.

    Micron took the lead by lending a Supermicro server with Micron NVDIMM-N to Calypso for testing. Calypso then installed CTS test software on the server to allow full testing to the PTS. Viking and SMART Modular contributed by helping dial in the drivers, as well as sending modules from Viking and SMART Modular to cross reference with the Micron modules. The test plan was comprised of several test iterations using single, dual and finally quad modules using each of the vendor contributed modules.

    The early single and dual module tests ran into repeatability and stability issues. NVDIMM-SIG consulted with Intel on the nuance of the Intel block IO driver while Calypso continued testing. The team successfully completed a test run that met the PTS steady state requirements on the quad module in time to release data for the show.

    We had a solid demonstration at the SNIA SSSI Flash Memory Summit Booth on NVDIMM-N Performance complete with marketing collateral available for review and a handout. NVDIMM-SIG members responded to the many questions and interest in the NVDIMM-N storage technology.

    “Once again,” said SSSI Chair Jim Ryan, “we can see the value and benefit of SNIA SSSI to its members, the SNIA educational community and the NVDIMM industry. I believe this is a great case study in how we all can contribute and benefit from working within the SSSI for the betterment of individual companies, market development and the Solid State Storage industry at large.” SSSI provides educational and marketing materials free of charge on its public website while SNIA SSSI members may join the NVDIMM-SIG and other SSSI committees.

    Data Recovery and Selective Erasure of Solid State Storage a New Focus at SNIA

    July 15th, 2015

    The rise of solid state storage has been incredibly beneficial to users in a variety of industries. Solid state technology presents a more reliable and efficient alternative to traditional storage devices. However, these benefits have not come without unforeseen drawbacks in other areas. For those in the data recovery and data erase industries, for example, solid state storage has presented challenges. The obstacles to data recovery and selective erasure capabilities are not only a problem for those in these industries, but they can also make end users more hesitant to adopt solid state storage technology.

    Recently a new Data Recovery and Erase Special Interest Group (SIG) has been formed within the Solid State Storage Initiative (SSSI) within the Storage Networking Industry Association (SNIA). SNIA’s mission is to “lead the storage industry worldwide in developing and promoting standards, technologies and educational services to empower organizations in the management of information.” This fantastic organization has given the Data Recovery and Erase SIG a solid platform on which to build the initiative.

    The new group has held a number of introductory open meetings for SNIA members and non-members to promote the group and develop the group’s charter. For its initial meetings, the group sought to recruit both SNIA members and non-members that were key stakeholders in fields related to the SIG. This includes data recovery providers, erase solution providers and solid state storage device manufacturers. Aside from these groups, members of leading standards bodies and major solid state storage device consumers were also included in the group’s initial formation.

    The group’s main purpose is to be an open forum of discussion among all key stakeholders. In the past, there have been few opportunities for representatives from different industries to work together, and collaboration had often been on an individual basis rather than as a group. With the formation of this group, members intend to cooperate between industries on a collective basis in order to foster a more constructive dialogue incorporating the opinions and feedback of multiple parties.

    During the initial meetings of the Data Recovery and Erase SIG, members agreed on a charter to outline the group’s purpose and goals. The main objective is to foster collaboration among all parties to ensure consumer demands for data recovery and erase services on solid state storage technology can be performed in a cost-effective, timely and fully successful manner

    In order to achieve this goal, the group has laid out six steps needed, involving all relevant stakeholders:

    1. Build the business case to support the need for effective data recovery and erase capabilities on solid state technology by using use cases and real examples from end users with these needs.
    2. Create a feedback loop allowing data recovery providers to provide failure information to manufacturers in order to improve product design.
    3. Foster cooperation between solid state manufacturers and data recovery and erase providers to determine what information is necessary to improve capabilities.
    4. Protect sensitive intellectual property shared between data recovery and erase providers and solid state storage manufacturers.
    5. Work with standards bodies to ensure future revisions of their specifications account for capabilities necessary to enable data recovery and erase functionality on solid state storage.
    6. Collaborate with solid state storage manufacturers to incorporate capabilities needed to perform data recovery and erase in product design for future device models.

    The success of this special interest group depends not only on the hard work of the current members, but also in a diverse membership base of representatives from different industries. We will be at Flash Memory Summit in booth 820 to meet you in person! Or you can visit our website at www.snia.org/forums/sssi for more information on this new initiative and all solid state storage happenings at SNIA.   If you’re a SNIA member and you’d like to learn more about the Data Recovery/Erase SIG or you think you’d be a good fit for membership, we’d love to speak with you.  Not a SNIA member yet?

    What a Solid State We Store In

    June 30th, 2014

    Note:  This blog entry is authored by SNIA Solid State Storage Initiative Governing Board member Gilda Fosswho serves on the SNIA Solid State Storage Initiative [SSSI] Governing Board as well as her role as Industry Evangelist in the CTO Office at NetApp, Inc

    Solid state drives use semiconductor chips, as opposed to magnetic media, to store data.  The chips that solid state drives use are non-volatile memory meaning that the data remains even when the system has no power.  I’ve written about solid state drive technology in the past and I will continue to, for it represents the first major advancement in primary storage in a very long time.  Serving on the Governing Board of the SNIA Solid State Storage Initiative, it allows me to help foster the growth and success of the market for solid state storage in both enterprise and client environments. Our goals are to be the recognized authority for storage made from solid state devices, to determine and document the characteristics of storage made from solid state devices, and to determine and document the impact of storage made from solid state devices on system architectures.

    So what can you expect if you were to ever upgrade to an SSD?  Well, for starters your computing experience will be transformed with screaming fast random access speeds, multi-tasking proficiency, as well as fantastic reliability and durability… and you can choose between an external SSD or even a hybrid drive so you’ve got some options.  A new SSD will make your system faster because the boot times will decrease, launching apps will be lightening fast, opening and saving docs will no longer drag, copying and duplicating file speeds will improve, and overall your system will have a new ‘pep in its step’.  Furthermore, to promote being green, SSDs consume far less power than traditional hard drives, which means they also preserve battery life and stay cooler.  Who doesn’t want and need that? They’re also very quiet, with none of the spinning and clanking you get with HDDs – for obvious reasons. SSDs are cooler and quieter, all the while being faster.

    Since modern SSDs are Flash-based, there is no real hard-defined difference between Flash and SSD.  Rather, as mentioned previously, Solid State Disk is essentially storage that doesn’t require moving parts and Flash is what allows that to exist.  SSDs use Flash instead of RAM these days, since it’s a type of memory that’s super fast and doesn’t require continuous power, making it non-volatile.  A match made in solid-state heaven.

    There are some fundamental aspects that folks expect from a robust flash-based storage solution.  First off, I/O performance and efficiency for many applications, including database acceleration, server and desktop virtualization, and cloud infrastructure.  You should also expect to speed up overall IT performance, boost responsiveness of performance-critical applications, and reduce power costs and over-provisioning.  Furthermore, you will obviously use more high-capacity, low-cost SATA drives while improving utilization of your data center space.  If you can achieve all your flash-based goals without changing your IT infrastructure management processes, then you’ve really got it good.

    Flash storage has customarily had substantial aging issues. In a nutshell, a user could only write to the memory a certain number of times before they would just lose that section of the drive coupled with the fact that performance would degrade over time, too.  However, a lot of these issues were resolved and companies started manufacturing SSDs out of Flash memory instead of out of RAM.

    I’ve stated in the past that many people in the industry believe that flash SSDs will eventually replace traditional hard drives.  By the time this happens other characteristics, such as slower write time and added cost, will likely have been eradicated or significantly diminished. Even today, an SSD can extend the life of a laptop battery, reduce the weight of the system, make it quieter, and increase read performance.  When properly and optimally engineered, SSDs are now at least as reliable as traditional spinning hard drives.  Relating to the faster speed, think of one starting up in seconds versus minutes. Even the slowest current SSD gives you much improved real-world performance than does the fastest conventional hard drive, perhaps even 100x as fast.  This allows for better user productivity, allowing for more work to get done in a fraction of the time.  Furthermore, using flash in enterprise storage servers means you can support more users, do more work, and use less power so it’s no wonder that it’s become an important technology for business transactions.   It’s a solid win-win-win.

    SSSI’s 2014 Mission

    This SNIA initiative was formed in September 2008 and its mission is to foster the growth and success of the market for solid state storage in both enterprise and client environments. Our goals are to be the recognized authority for storage made from solid state devices, to determine and document the characteristics of storage made from solid state devices, and to determine and document the impact of storage made from solid state devices on system architectures.  Additionally, the SSSI collects solid state technical requirements of storage system vendors and communicate to SSD manufacturers for common features, behavior, and robustness.  The initiative collaborates with academia and the research labs of member companies to understand how advances in solid state memory will impact storage made from solid state memory as well as to educate the vendor and user communities about storage made from solid state devices.

    The SNIA SSSI also coordinates education activities with the Education Committee, performs benchmark testing to highlight the performance advantages of solid state storage, create peer reviewed vendor neutral SNIA Tutorials, and create vendor-neutral demonstrations.  The SSI also leverages SNIA and partner conferences, collaborate with industry analysts, perform market outreach that highlights the virtues of storage made from solid state devices.  The initiative determines what technical work should be performed within SNIA technical working groups to further the acceptance of storage made from solid state devices.  Furthermore and very importantly, the SSSI determines the standards that will be necessary to support the industry usage of SSDs by performing interoperability plug-fests as necessary in support of standards development.

    Collaboration between other SNIA organizations is also key.  The SSSI works with the Storage Management Initiative (SMI) to understand how SMI-S can be used to manage storage made from solid state devices.  We also work with the Green Storage Initiative (GSI) to understand how storage made from solid state devices will impact energy use in computer systems.  The work that the SSI does with the Technical Council helps create the desired technical working groups and provides external advocacy and support of these technical working groups.

    Finally, the SSSI collaborates with other industry associations via SNIA’s Strategic Alliances Committee (SAC) on SSD-related technical work in which they are involved as well as coordinates with SNIA Regional Affiliates to ensure that the impact of the SSS Initiative is felt worldwide.  For more information, please visit http://www.snia.org/forums/sssi
