Three Truths About Hard Drives and SSDs

An examination of the claim that flash will replace hard drives in the data center

“Hard drives will soon be a thing of the past.”

“The data center of the future is all-flash.”

Such predictions foretelling hard drives’ demise, perennially uttered by a few vocal proponents of flash-only technology, have not aged well.

Without question, flash storage is well-suited to support applications that require high-performance and speed. And flash revenue is growing, as is all-flash-array (AFA) revenue. But not at the expense of hard drives.

We are living in an era where the ubiquity of the cloud and the emergence of AI use cases have driven up the value of massive data sets. Hard drives, which today store by far the majority of the world’s exabytes (EB), are more indispensable to data center operators than ever. Industry analysts expect hard drives to be the primary beneficiary of continued EB growth, especially in enterprise and large cloud data centers—where the vast majority of the world’s data sets reside.

The SNIA booth will feature cloud infrastructure and storage discussions and a demonstration of a multi-vendor persistent memory solution featuring NVDIMM!  (P.S. – Are you new to containers? Get a head start on conference discussions by checking out a December 2016 SNIA blog on Containers, Docker, and Storage.)  

Closing out February, find SNIA at their booth at USENIX FAST from February 27-March 2 in Santa Clara, CA, where you can engage with SNIA Technical Council leaders on the latest activities in file and storage technologies.

We look forward to seeing you at one (or more) of these events!

 

We’ve Been Thinking…What Does Hyperconverged Mean to Storage?

Here at the SNIA Ethernet Storage Forum (ESF), we’ve been discussing how hyperconverged adoption will impact storage. Converged Infrastructure (CI), Hyperconverged Infrastructure (HCI), along with Cluster or Cloud In a Box (CIB) are popular trend topics that have gained both industry and customer adoption. As part of data infrastructures, CI, HCI, and CIB enable simplified deployment of resources (servers, storage, I/O networking, hypervisor, application software) across different environments.

But what do these approaches mean for the storage environment? What are the key concerns and considerations related specifically to storage? How will the storage be connected to (or included in) the platform? Who will protect and backup the data? And most importantly, how do you know that you’re asking the right questions in order to get to the right answers?

Find out on March 15th in a live SNIA-ESF webcast, “What Does Hyperconverged Mean to Storage.” We’ve invited expert Greg Schulz, founder and analyst of Server StorageIO, to answer the questions we’ve been debating. Join us, as Greg will move beyond the hype (pun intended) to discuss:

  • What are the storage considerations for CI, CIB and HCI
  • Why fast applications and fast servers need fast I/O
  • Networking and server-storage I/O considerations
  • How to avoid aggravation-causing aggregation (bottlenecks)
  • Aggregated vs. disaggregated vs. hybrid converged
  • Planning, comparing, benchmarking and decision-making
  • Data protection, management and east-west I/O traffic
  • Application and server north-south I/O traffic

Register today and please bring your questions. We’ll be on-hand to answer them during this event. We hope to see you there!

Buffers, Queues, and Caches, Oh My!

Buffers and Queues are part of every data center architecture, and a critical part of performance – both in improving it as well as hindering it. A well-implemented buffer can mean the difference between a finely run system and a confusing nightmare of troubleshooting. Knowing how buffers and queues work in storage can help make your storage system shine.

However, there is something of a mystique surrounding these different data center components, as many people don’t realize just how they’re used and why. Join our team of carefully-selected experts on February 14th in the next live webcast in our “Too Proud to Ask” series, “Everything You Wanted to Know About Storage But Were Too Proud To Ask – Part Teal: The Buffering Pod” where we’ll demystify this very important aspect of data center storage. You’ll learn:

  • What are buffers, caches, and queues, and why you should care about the differences?
  • What’s the difference between a read cache and a write cache?
  • What does “queue depth” mean?
  • What’s a buffer, a ring buffer, and host memory buffer, and why does it matter?
  • What happens when things go wrong?

These are just some of the topics we’ll be covering, and while it won’t be exhaustive look at buffers, caches and queues, you can be sure that you’ll get insight into this very important, and yet often overlooked, part of storage design.

Register today and spend Valentine’s Day with our experts who will be on-hand to answer your questions on the spot!

The Changing World of SNIA Technical Work – A Conversation with Technical Council Chair Mark Carlson

carlson_mark_resizeMark Carlson is the current Chair of the SNIA Technical Council (TC). Mark has been a SNIA member and volunteer for over 18 years, and also wears many other SNIA hats.   Recently, SNIA on Storage sat down with Mark to discuss his first nine months as the TC Chair and his views on the industry.

SNIA on Storage (SoS):  Within SNIA, what is the most important activity of the SNIA Technical Council?

Mark Carlson (MC): The SNIA Technical Council works to coordinate and approve the technical work going on within SNIA. This includes both SNIA Architecture (standards) and SNIA Software. The  work is conducted within 13 SNIA Technical Work Groups (TWGs).  The members of the TC are elected from the voting companies of SNIA, and the Council also includes appointed members and advisors as well as SNIA regional affiliate advisors. SNIA_Technology_Infographic_4

SoS:  What has been your focus this first nine months of 2016?   

MC: The SNIA Technical Council has overseen a major effort to integrate a new standard organization into SNIA.  The creation of the new SNIA SFF Technology Affiliate (TA) Technical Work Group has brought in a very successful group of folks and standards related to storage connectors and transceivers. This work group, formed in June 2016, carries forth the longstanding SFF Committee work efforts that has operated since 1990 until mid-2016.  In 2016, SFF Committee leaders transitioned the organizational stewardship to SNIA, to operate under a special membership class named Technology Affiliate, while retaining the long standing technical focus on specifications in a similar fashion as all SNIA TWGs do.

SoS:  What changes did SNIA implement to form the new Technology Affiliate membership class and why?

MC: The SNIA Policy and Procedures were changed to account for this new type of membership.  Companies can now join an Affiliate TWG without having to join SNIA as a US member.  Current SNIA members who want to participate in a Technology Affiliate like SFF can join a Technology Affiliate and pay the separate dues.  The SFF was a catalyst – we saw an organization looking for a new home as its membership evolved and its leadership transitioned.  They felt SNIA could be this home but we needed to complete some activities to make it easier for them to seamlessly continue their work.   The SFF is now fully active within SNIA and also working closely with T10 and T11, groups that SNIA members have long participated in.

SoS:  Is forming this Technology Affiliate a one-time activity?

MC: Definitely not.  The SNIA is actively seeking organizations who are looking for a structure that SNIA provides with IP policies, established infrastructure to conduct their work, and 160+ leading companies with volunteers who know storage and networking technology.

SoC:  What are some of the customer pain points you see in the industry?

MC: Critical pain points the TC has started to address with new TWGs over the last 24 months include: performance of solid state storage arrays, where the SNIA Solid State Storage Systems (S4) TWG is working to identify, develop, and coordinate system performance standards for solid state storage systems; and object drives, where work is being done by the Object Drive TWG to identify, develop, and coordinate standards for object drives operating as storage nodes in scale out storage solutions.  With the number of different future disk drive interfaces emerging that add value from external storage to in-storage compute, we want to make sure they can be managed at scale and are interoperable.TC org chart 2016

SoS:  What’s upcoming for the next six months?

MC: The TC is currently working on a white paper to address data center drive requirements and the features and existing interface standards that satisfy some of those requirements.  Of course, not all the solutions to these requirements will come from SNIA, but we think SNIA is in a unique position to bring in the data center customers that need these new features and work with the drive vendors to prototype solutions that then make their way into other standards efforts.  Features that are targeted at the NVM Express, T10, and T13 committees would be coordinated with these customers.

SoS:  Can non-members get involved with SNIA?

MC:   Until very recently, if a company wanted to contribute to a software project within SNIA, they had to become a member. This was limiting to the community, and cut off contributions from those who were using the code, so SNIA has developed a convenient Contributor License Agreement (CLA) for contributions to individual projects.  This allows external contributions but does not change the software licensing. The CLA is compatible with the IP protections that the SNIA IP Policy provides to our members.  Our hope is that this will create a broader community of contributors to a more open SNIA, and facilitate open source project development even more.

SoS:  Will you be onsite for the upcoming SNIA Storage Developer Conference (SDC)?

MC: Absolutely!  I look forward to meeting SNIA members and colleagues September 19-22 at the Hyatt Regency Santa Clara.  We have a great agenda, now online, that the TC has developed for this, our 18th conference, and registration is now open.  SDC brings in more than 400 of the leading storage software and hardware developers, storage product and solution architects, product managers, storage product quality assurance engineers, product line CTOs, storage product customer support engineers, and in–house IT development staff from around the world.  If technical professionals are not familiar with the education and knowledge that SDC can provide, a great way to get a taste is to check out the SDC Podcasts now posted, and the new ones that will appear leading up to SDC 2016.
