The following post is an excerpt of an article Objective Analysis submitted to the Pund-IT Weekly Review for 11 March, 2015.
With a webcast in the style of the big system makers like EMC and Oracle, SanDisk announced its InfiniFlash flash appliance. InfiniFlash is a box that crams a whopping 500 terabytes into only 3U of rack space.
How big is 500 terabytes? It’s more bytes than SanDisk’s entire flash output for 2001.
SanDisk boasts that InfiniFlash is a “category-defining product”, and pointed to the fact that IDC, who provided support for the roll-out, created a new “Big Data Flash” storage product category for this device.
The system boasts performance of one million random-read IOPS, which is impressive, but doesn’t give much indication of how it performs in standard enterprise dataflow, which is generally assumed to consist of a 70/30 split of reads and writes. (I should mention here that Objective Analysis published a survey of users’ IOPS and latency needs which can be purchased on our website.)
Price is a major focus for this product. SanDisk says that it will sell systems bundled with software at less than Continue reading “SanDisk Rolls Out InfiniFlash”
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 “Skyera Launches 500TB 1U Flash Box”
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 “Webinar: Flash Best Practices”
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 “IBM Makes Flash Even Faster”
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.
Our webcast, titled SPDEcon Solid State Preview, presents snippets of Continue reading “SPDEcon Sneak Peek”
SSD-watchers have expressed some concern over the last few years that SSDs cannot be manufactured using advanced NAND flash process geometries. This is because these parts have lower endurance and a larger number of bit errors than NAND made using less-advanced processes – the tighter the process, the shorter the flash’s life, and the more errors it will have.
Fortunately these concerns seem to be Continue reading “19nm & 20nm SSDs Arrive!”
