Violin Memory and Microsoft have jointly announced a novel way of harnessing the power of Windows Server software. Violin will be shipping its memory arrays with a special version of Windows Server 2012 R2 pre-installed on the embedded server that manages the internal operations of Violin’s all-flash array.
Violin explains that native support of specially-optimized versions of Windows Server and System Center that have been tuned for an all-memory array will provide improved performance and economics for large-scale enterprise cloud deployments.
The system can internally run Continue reading
SSD spec sheets, might lead you to believe that power is just not an issue. For example, Samsung lists the power use for a 512GB 830 SSD at 0.127W (typical) for “Active Power Use”. This implies very low demands on the system power supply.
If you do some more research, you find that the peak power usage is a lot higher. AnandTech, in a review article reports sequential write power draw at 5.14W and random write power draw at 5.8W. In that 2.5” SSDs use the 5V power rail exclusively, this is more than Continue reading
Skyera, a flash appliance start-up, has been working for some time to amaze would-be flash users. The company takes advantage of the most advanced flash processes and non-SSD formats to squeeze as much flash as possible into a 1U cabinet.
Not content with the 44TB maximum of its original 1U skyHawk product (based on 19/20nm NAND chips from Micron and Toshiba) the company, at the Flash Memory Summit, introduced its new product, skyEagle, a system that provides up to 500TB of storage in the same Continue reading
Violin Memory has introduced the 6264 array, doubling the capacity of its earlier 6232 product from 32 terabutes (TB) to 64TB, while remaining in the same form factor. The company has done this by migrating to 19nm MLC NAND flash from Toshiba.
Violin says that this move was made possible by the fact that the company’s arrays aren’t built using standard SSDs, and claims that this has caused Violin’s all flash array revenues to be significantly higher than those of any of its competitors.
With this product the company doubles its power efficiency, when measured in watts per gigabyte, and boosts its Continue reading
Nimbus has introduced its 4th generation Gemini flash array, which the company claims to be the first to use 1xnm NAND flash chips. Along with this announcement Nimbus has reduced pricing by 35% and has increased performance from 2-4 times that of its earlier-generation products.
Using Nimbus’ HALO software the company says it can achieve a cost of $0.78 per usable gigabyte, or about 1/3rd the cost of a comparable hybrid storage array.
The Gemini array uses redundant Continue reading
I had the opportunity to participate in a round table webinar covering the best practices for solid state storage on July 18. The hour-long session (including Q&A) can be replayed at BrightTalk.
In this round table webinar entitled Best Practices for Solid State Storage Implementation storage analyst Tom Coughlin moderated three of us, Radoslav Danilak of Skyera, Esther Spanjer of SMART Storage Solutions, and The SSD Guy (Yours Truly) in a Continue reading
Today Kaminario added a performance guarantee and a 7-year warranty to its arsenal. The company introduced its “Consistency Under Failure Guarantee” which ensures customers will see no more than a 25% drop in performance during a system failure. This means that critical operations and applications can continue to run at near-standard performance despite the failure of an SSD or even an entire node. Kaminario president Dani Golan told The SSD Guy last week that this is a conservative guarantee, and that few customers see more than a 10% degradation during failure tests in their own production systems.
As for the 7-year flash endurance warranty, no matter which SSD Continue reading
At IBM’s Edge 2013 conference last week the company not only extolled the values of flash, as does anyone who has had a flash experience, but it also showed how flash could be made even faster than it already is.
You’re probably already thinking: “Flash is about 1,000 times as fast as HDD – how do you make it even faster?”
The answer is actually pretty simple: compress the data. If there is a limit to how much bandwidth you have going into and out of a piece of storage, you can speed it up if you can reduce the size of the data that consumes that bandwidth.
Of course, that’s not always easy. Compression often slows data access down, even for HDDs, and it could Continue reading
Viking Technology on Wednesday announced that the company has arranged with SuperMicro to deliver solutions that should solve issues key to flash storage array designers. Supermicro will ship server boards that have all the hooks necessary to support Viking’s nonvolatile DDR3 DIMMs without users having to wait for this kind of support to arrive in servers based on the standard Intel platform.
Viking’s marketing folks tell me that NV-DIMM support is something that its customers have been asking for, and that it will be a standard component of Continue reading
We have just finished up a webcast (now available for replay) that gives a preview of five of the solid state storage presentations that will be given at the upcoming Storage Plumbing and Data Engineering Conference – SPDEcon for short – hosted by the Storage Networking Industry Association (SNIA) on June 10-12 at the Hyatt Regency hotel in Santa Clara, California.
