SNIA’s Non-Volatile DIMM (NVDIMM) Special Interest Group (SIG) had a tremendous response to their most recent webcast: NVDIMM: Applications are

Viewers had many questions during the webcast. In this blog, the NVDIMM SIG answers those questions and shares the SIG’s knowledge of NVDIMM technology. Read More
New on the Solid State Storage website is a whitepaper from analysts Tom Coughlin of Coughlin Associates and Jim Handy of Objective Analysis which details what IT manager requirements are for storage performance.The paper examines how requirements have changed over a four-year period for a range of applications, including databases, online transaction processing, cloud and storage services, and scientific and engineering computing. Users disclose how many IOPS are needed, how much storage capacity is required, and what system bottlenecks prevent them for getting the performance they need. Read More
Over 150 individuals participated in the BrightTALK Enterprise Storage Summit NVDIMM webcast. If you are eager for more information on NVDIMM, you will want to attend an upcoming SNIA Event – the Storage Industry Summit on Non–Volatile Memory.
This Summit will take place at the Sainte Claire Hotel in San Jose, CA on January 28th as part of the SNIA Annual Members’ Symposium, and will offer critical insights into NVM, including NVDIMMs, and the future of computing. This event is complimentary to attend and you can register here.
The Summit will take place from 8:15 AM to 5:30 PM and speakers currently include:

Need an abbreviated version of the SNIA SSD Performance Test Specification (PTS) in a hurry? Jamon Bowen of Texas Memory Systems (TMS) whipped up a simple implementation of certain key parts of the PTS that can be run on a Linux system and interpreted in Excel.
It’s a free download on his Storage Tuning blog.
This is a boon for anyone that might want to run a internal preliminary test before pursuing a more formal route.
The bash script uses the Flexible I/O utility (FIO) to run through part of the SSSI PTS. FIO does the heavy lifting, and the script manages it. The script outputs comma separated (CSV) data and the download includes an Excel pivot table that helps format the results and select the measurement window.
Since this is a bare-bones implementation the SSD must be initialized manually before the test script is run.
The test runs the IOPS Test from the PTS. This test covers a range of block sizes, read/write ratios and iterates until the steady state for the device is reached (with a maximum of 25 iterations). Altogether the test takes over a day to run.
Once the test is complete, the downloadable pivot tables allow users to select the steady-state measurement window and report the data in a recommended format.
See Mr. Bowen’s blog at http://storagetuning.wordpress.com/2011/11/07/sssi-performance-test-specification/ for details on this valuable download.
