At the most recent Flash Memory Summit in August 2014, the SNIA NVM Programming Model was selected for a singular honor – industry recognition as a Best of Show for Enterprise Business Applications. Being recognized was quite unique, as the Model is not a product or a solution as were other winners in the various categories; but rather a body of work that defines new software programming models for non-volatile memory, also known as NVM.
NVM technologies are currently advancing in such a way as to blur the line between storage and memory – which will radically transform the way software is written. The NVM Programming Model embraces this transformation, describing behavior provided by operating systems that enables applications, file systems, and other software to take advantage of new NVM capabilities.
The Model addresses NVM extensions for existing devices such as SSDs and persistent memory, describing the differences between software written for block storage (SSDs and disks) and persistent memory, and outlining the potential benefits for adapting software for persistent memory.
In presenting the Award to Doug Voigt, co-chair of the SNIA NVM Programming Technical Work Group, Jay Kramer, Chairman of the Flash Memory Summit Awards Program and President of Network Storage Advisors Inc., stated, “Flash memory technology is currently experiencing a progression of innovations that can make a real difference in solving storage solution challenges. The industry is seeing a proliferation of new Non–Volatile Memory (NVM) functionality and new NVM technologies. We are proud to select the SNIA NVM Programming Model for the Best of Show Award as it brings to the marketplace a new standard with a model that defines recommended behavior between various user spaces and operating system (OS) kernel components supporting NVM.”
Congratulations to the many SNIA member company contributors to the Programming Model for this honor! For information and to download the specification, visit http://www.snia.org/forums/sssi/nvmp.

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!
Go to http://www.snia.org/forums/sssi/wiocp for a FAQ and details on participating. And see results at http://iotta.snia.org/

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!
