I like efficiency and efficient products.
With recent article of VMware Storage blog which took all my attention I discovered new company which was presenting first flash based array at VMworld 2011 at Las Vegas. Unfortunately I was not present, but what was said on the Storage blog is very interesting indeed.
A quick quote:
PureStorage uses lower-cost MLC (multi-level cell) flash, along with deduplication and compression to make the cost per GB of flash relatively cheap. This flash array should give you persistent I/O latency in the region of 100s of microseconds rather than 10s of milliseconds which is what you typically see with spinning disks.
I went and took a look at the company's website to find some more informations. Especially the deduplication options are quite interesting which claimed to save 10x of space.
But what about aging of Flash drives? See this video from PureStorage about it… Actually you'll get a good idea of how the bit error is involved in the aging of flash drives.
And here is the Video.
Enjoy.. -:)
we discuss the realities of a controversial and often misunderstood characteristic of flash: aging. Most people understand that with every program/erase cycle Flash is slowly worn down, but how does this aging really work, and how can Flash be made to withstand typical 5-7 year enterprise duty-cycles?
