Virident, a maker of server-side flash storage, like Stec before it, will become part of Western Digital’s HGST subsidiary.
EMC sees the appeal of flash storage but maintains that hybrid arrays still suit most customer requirements.
Flash storage startup Skyera has scored $51.6 million in second round funding led by Dell Ventures. With Dell, Skyera gets a potential sales channel and Dell gets tech to sell to its cloud and webscale customers.
If you wanted to use Pure Storage’s FlashArrays but weren’t a Fibre Channel shop, you were out of luck. Untill now. The startup has added 10GbE and iSCSi support — as well as snapshotting capabilities — to its solid state storage arrays.
NetApp is working with Fusion-io to make server-side flash a resource for storing “hot” data. The company said its Flash Accel software can boost application performance up to 90 percent in some cases.
The Gemini flash array is the first of what will probably be many solid-state storage products announced this week. Nimbus Data says the new array will cut all-in storage cost to $8 per GB from $10 per GB for its previous model.
What a week for flash storage fans. IBM snapped up flash memory maker Texas Memory Systems; Skyera emerged from stealth mode with a jaw-dropping $3 per GB all-flash array and Pure Storage, another flash storage startup, recently landed $40 million in funding. All this news comes in advance of the Flash Memory Summit in Santa Clara, CA next week. So what’s behind the flash splash?
Until recently flash storage was a niche market. It was targeted primarily at applications where consistency and low latency are a requirement, such as databases, virtual desktops, gaming sites and financial trading systems. But with falling prices and improved reliability it’s starting to make inroads into the enterprise, and that’s where the big bucks are in storage. According to Gartner, the flash market in enterprise storage is expected to be worth $4 billion by 2015.
But before you relegate tried and true hard disk drives to the technology graveyard, consider the quirks of solid-state drives (SSDs). For one, flash memory has a finite write lifetime, so SSDs eventually wear out. Typically, SLC flash lasts for approximately 100,000 write cycles; MLC flash is an order of magnitude worse at around 10,000 cycles for individual data cells. Beyond those points, storing and retrieving data becomes unreliable. Flash manufacturers use a number of techniques to extend life, including error correction codes, wear leveling, bad block re- mapping and over provisioning. But none of these workarounds prolongs the life of SSDs to the reliability of their spinning disk counterparts. So it’s important to understand the wear and tear issues with flash storage before deploying it.
For a heads-up on how others are using SSDs, the enterprise applications track at the Flash Storage Summit has some interesting speakers discussing the use of flash drives in the healthcare and media sectors. My two cents: flash storage will become another storage tier in the enterprise for apps that need blazingly fast response times, but for everything else, the price of disk continues to drop way faster than flash storage is dropping and will not replace primary disk storage any time soon.
Question of the week
The flash memory land rush continues with IBM buying Texas Memory Systems and its RamSan line this week. The news comes as flash storage startups touting flash-everywhere game plans are reaping big VC investments. IBM rival EMC bought EXtremeIO a few months ago.
It’s all-flash, all the time for Pure Storage, the Mountain View startup that just netted another $40 million to pursue that goal. The funding will go toward fueling a global push and staffing up sales and engineering teams, the company said.
Watch out hard drives — slick startup Skyera, launched by the founder of SandForce, says it really can put flash storage everywhere — without breaking the bank. It’s a bold claim but one that’s backed up with some pretty credible storage expertise.
