The SNIA Solid State Storage Initiative (SNIA SSSI) is working to better understand disk drive use in everyday computer actions. You can help by participating in our Workload I/O Capture Project – WIOCP – and get rewarded!

The WIOCP captures I/O statistics unobtrusively and without compromising your PC’s performance. No personal data or content is captured – only statistics on the types of data transfers that occur.  This helps the SNIA SSSI and the industry understand what actually takes place with your drive when you use your PC.

Collecting I/O statistics helps computer scientists determine the type of workloads your drive is experiencing.  By capturing statistics from a large number of computer users, designers can optimize both the drive and the host computer system to improve your overall computing experience.  You can be a part of history!

Participate NOW and return one set of statistics to qualify to win a $10 Amazon gift card and to be  entered in a drawing for a free Intel 120GB SSD.  Submit more sets and increase your chance of winning a SSD!

If 2013 was the year of software-defined everything, of everything-as-a-service, and big data – what’s on the horizon for storage in 2014? What do we still need to know about the innovations of this year? What hard realities have been missing from the hype? In the  Enterprise Storage Summit, https://www.brighttalk.com/summit/2271, a bi-annual event from BrightTALK, top thought leaders from all over the globe gather to share their insights into one of the most difficult areas of IT infrastructure and shed light on some of the most crucial topics facing enterprises today, including backup/recovery, hardware innovations, continued transition to cloud storage and the implications of big data.

On December 5 at 9:00 am Pacific/12:00 noon Eastern, learn how Non-Volatile DIMMs, or NVDIMMs, provide a persistent memory solution with the endurance and performance of DRAM coupled with the non-volatility of Flash. This webinar, presented by Jeff Chang of AgigaTech, will provide a general overview of this emerging technology and why the industry is starting to take notice.

You will learn what an NVDIMM is, how it works, where it fits and why every system architect should consider them for their next generation enterprise server and storage designs.

A new revision of the Enterprise Solid State Storage Performance Test Specification (PTS–E 1.1) is now available for public review. The PTS is an industry standard test methodology and test suite for the comparison of SSD performance at the device level. The PTS–E 1.1 updates the PTS–E 1.0 released in 2011 and adds tests with specific types of workloads common in the enterprise environment. The PTS–E 1.1 may be downloaded at http://www.snia.org/publicreview.

“The PTS–Enterprise v1.1 provides both standard testing (IOPS, Throughput, Latency, and Write Saturation) as well as new tests for specific workloads commonly found in Enterprise environments,” said Eden Kim, Chair of the SSS Technical Work Group. “These new tests also allow the user to insert workloads into the new tests while maintaining the industry standard methodology for pre conditioning and steady state determination.”

The new tests target workloads common to OLPT, VOD, VM, and other enterprise applications while paying special attention to the optimization of drives for varying demand intensity, maximum IOPS and minimal response times and latencies.

SNIA’s SSSI channel webcast of “How Many IOPS Is Enough?” was a smash success!  Now you can listen to an on demand rebroadcast.

Even though there are lots of SSDs on the market today offering IOPS (I/Os Per Second) performance in the thousands to hundreds of thousands (with indications that future models will offer speeds in the million-IOPS range), and HDDs that support from tens to hundreds of IOPS depending on spindle speed and interface, not every application can use the extreme performance of high-end SSDs, and some may not benefit from high IOPS at all.

Since performance is tied to cost, users can save money if they understand how many IOPS the system really needs.  “How Many IOPS is Enough?” draws from the recent study by Coughlin Associates and Objective Analysis that examined what makes an application require high IOPS and which profiled applications according to their needs.

In the webcast, you will also learn how to take part in an exciting SSSI project – the Workload I/O Capture Program, or WIOCP, a simple tool that captures software applications’ I/O activity by gathering statistics on workloads at the user level (IOPS, MB/s, response times queue depths, etc).  The WIOCP helps users to identify “Hot Spots” where storage performance is creating bottlenecks. SNIA SSSI hopes that users will help the association to collect real-use statistics on workloads by uploading their results to the SNIA website. Details on WIOCP can be found at tinyurl.com/tryWIOCP.

SNIA’s Solid State Storage Initiative (SSSI) recently rolled out its new Workload I/O Capture Program, or WIOCP, a simple tool that captures software applications’ I/O activity by gathering statistics on workloads at the user level (IOPS, MB/s, response times queue depths, etc).  The WIOCP helps users to identify “Hot Spots” where storage performance is creating bottlenecks. SNIA SSSI hopes that users will help the association to collect real-use statistics on workloads by uploading their results to the SNIA website.

How it works
The WIOCP software is a safe and thoroughly-tested tool which runs unobtrusively in the background to constantly capture a large set of SSD and HDD I/O metrics that are useful to both the computer user and to SNIA. Users simply enter the drive letters for those drives for which I/O operations metrics are to be collected. The program does not record anything that might be sensitive, including details of your actual workload (for example, files you’ve accessed.) Results are presented in clear and accessible report formats.

How would the WIOCP help me as a user of computer systems?
Our upcoming white paper gives many reasons why you would want to download and run the WIOCP.  One reason is that empirical file and disk I/O operation performance metrics can be invaluable with regard to theories and claims about disk I/O performance. This is especially so when these metrics reflect the actual file and disk I/O operation activity performed by individual applications/workloads during normal usage. Moreover, such empirical I/O metrics can be instrumental in uncovering/understanding performance “bottlenecks”, determining more precise I/O performance requirements, better matching disk storage purchases to the particular workload usage/needs, and designing/optimizing various disk storage solutions.

How can I help this project?
by downloading and running the WIOCP you help us collect I/O metrics, which can reveal insights into the particular ways that applications actually perform and experience I/O operation activity in “real-life” use. And using this information,  SNIA member companies will be able to improve the performance of their solid state storage solution, including SSDs and flash storage arrays. Help SNIA get started on this project by clicking http://www.hyperIO.com/hIOmon/hIOmonSSSIworkloadIOcaptureProgram.htm and using the “Download Key Code” enter SSSI52kd9A8Z. The WIOCP tool will be delivered to your system with a unique digital signature. The tool only takes a few minutes to download and initialize, after which you can return to the task at hand!

The media buzz continues on solid state storage, now a prominent feature of storage, virtualization, and developer discussions.  Reaching the ears of business is SSSI’s Marketing Committee Chair Tom Coughlin, who has a blog on Forbes.  Latest posts discuss  a new age of digital storage interfaces, many based on the PCIe computer interface, that can take advantage of the higher data rates that NAND flash-based digital storage can provide.

Solid State Storage was featured at recent storage conferences including SNIA’s Storage Developer Conference and SNW (Storage Networking World) US and Europe.  At SNW US, Lucas Mearian of Computerworld and Jim Pappas, SNIA Board and SSSI member, discussed a sea change in the non-volatile memory (NVM) market over the next five years, with more dense and reliable technologies challenging dominant NAND flash memory now used in solid-state drives (SSD) and embedded in mobile products.  Mearian’s article is here.

At Powering the Cloud – SNW Europe, Randy Kerns of the SNIA member Evaluator Group led a spotlight session on Solid State Storage and Its Impact on the Environment, with presentations from SSSI members Kim Gardner of STEC and David Dale of NetApp.

SNIA and the Solid State Storage Initiative urge you to get involved in fast-developing SSSI activities in PCIe and NVM.  Visit our website at http://www.snia.org/forums/sssi or email asksssi@snia.org
