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
Today NAND flash is being shoehorned into HDD formats simply because it is persistent – the data doesn’t disappear when the lights go out. This approach fails to take advantage of NAND’s greatest strength – its low cost relative to DRAM – and this prevents it from fully meeting the needs of most data centers.
Since 2004 NAND has been cheaper than DRAM, and today its price per gigabyte is an order of magnitude lower than that of DRAM. NAND is cheaper and slower than DRAM, and HDD is cheaper and slower than NAND.
A role better suited to NAND flash technology is Continue reading
I can already hear readers saying: “Wait! You can’t do that!” Well, you’re right, but the new module comes awfully close to that by putting the NAND behind an ASIC that interfaces between the DDR3 bus and the NAND.
Why do this? Quite simply because you can get more “Bang for the Buck” by adding NAND to the system once you’ve reached a certain DRAM size. The Diablo “Memory Channel Storage” (MCS) approach supports the addition of terabytes of NAND at the loss of Continue reading
OCZ has just introduced a new software/hardware combination aimed at accelerating the performance of Microsoft SQL Server. The OCZ ZD-XL SQL Accelerator combines a custom PCIe SSD with caching software optimized for the SQL Server workload. The company boasted that this product won the “Best of Interop 2013″ award, a distinction certainly worth crowing about!
How does this product differ from standard caching software? OCZ tells us that the key elements required to 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
The following is excerpted from an Objective Analysis Alert e-mailed to our clients on 2 July, 2013:
SanDisk Corporation announced on 2 July 2013 an agreement to acquire SMART Storage Systems, the SSD arm of SMART Modular Technologies, for $307 million in cash and equity. The transaction is expected to close in August, 2013.
SMART has strong SSD technology that allows the company to ship MLC-based SSDs with endurance specifications superior to those of some SLC SSDs. The SSD maker had shipments of about $25M in its most recent quarter.
The SMART acquisition will be the fourth 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
The following is excerpted from an Objective Analysis Alert e-mailed to our clients on 24 June, 2013:
Western Digital Corporation (WDC) and sTec, Incorporated announced today an agreement for sTec to be acquired by WDC for $340 million in cash. The HGST subsidiary will assume control of sTec and will continue to support existing sTec products and customers, while also remaining a part of its joint development program with Intel Corp. HGST’s current line of SSDs uses an Intel controller architecture combined with an SAS interface, end-to-end data protection, and other features key to the enterprise SSD marketplace.
Although sTec was a glorious first mover in the SSD business with EMC’s Continue reading
- Support for multiple SSDs of mixed sizes and types
- Concatenation of two or more SSDs into a single caching volume
- SSD mirroring for “Safe Write-Back” caching
- A maximum cache size increase from 1TB to 2TB
- 2,048 accelerated objects can be stored in each cache, up from the earlier release’s 255
The company prides itself in the ease with which the software and a server-side SSD can be added to a system without otherwise changing its storage architecture.
With the “Safe Write Back” feature the FlashSoft software has been upgraded 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
