Coming soon: The solid state server and TVs with auto-rewind

Flash memory makers have taken over cell phones and MP3 players and want to start moving into notebooks. So what's next on the colonization roadmap?

Servers, says Frankie Roohparvar, vice president of NAND development at Micron Technologies. Server makers are looking at ways of replacing drives in servers.

"That is the area where they (the hard drive industry) are weakest next," he said over a lunch meeting.

It sounds weird initially. Servers typically come with large drives, and flash memory costs around 10 times as much as space on drives, when you look at it from a cost per bit point of view.

Performance, however, is a key consideration in many segments of the server market. In some servers, data is actually only stored on the perimeter of the hard drive for more rapid access, he asserted. Thus, much of the storage space goes fallow, which in turn shrinks the cost delta between hard drives and flash.

Plus, energy consumption goes down. That's a favorite on the IT buyer checklist.

"Most of the major guys in servers are looking at this," he said.

Last month, IBM said it would begin to offer a solid state drive (from SanDisk) as an option on its blade servers.

TVs will be another growing market, said Roohparvar. Many TV makers are inserting flash into upcoming digital TVs. The memory will cache incoming TV programs so that viewers at home can rewind. You can do it now with some TVs and TiVo boxes, but now it will be standard in more TVs.

Some TVs are already out on the market, but Roohparvar said many have been designed but haven't been announced yet. Thus, I'd say look for these at CES, as well as another round of "TiVo is toast" stories.

The hard drive-flash fight will be a great one to watch. Both industries are fairly competitive. (Micron, for one, is run by an extreme sports junkie that had his executive team race the Baja 500.) Losing millions a quarter just to stay in the game is pretty much par for the course for some manufacturers and manufacturing capacity for both industries is pretty high. Hence you can expect storage capacities to increase and prices to continue to plummet. (Flash has dropped 60 percent a year for the last two years and drives have been on a similar trajectory.) For consumers, that's good.

Flash Subject to degrading stability

Flash memory has been documented as having failures when written over 1000's of times. While this limit may serve no problems to devices like MP3 players or thumb drives that only get new data on occassion, a hard drive receives new information on a regular basis. Just using it as virtual memory subjects it to an incredible amount of read/write cycles. What do flash makers intend to do if their memory starts failing when used as a replacement for a hard drive? I can see flash failing in less than 100 days on a server running continuously under these conditions. Has this problem been fixed? I ask the editors at cnet to look into this and provide an article showing the differences between flash and traditional hard drives and what we might expect as far as performance, durability, reliability, economy, total cost of ownership.... How do they stack up side by side?

Re:

You can be quite certain that if IBM is planning on using such a storage medium in their servers, there have been many months of testing going on to verify the reliabity and functionality of said medium.

Not so much anymore

Whereas degradation was a problem 3-5 years ago, the industry has moved to a point where its more like 20,000 writes cycles before a given area of memory becomes degraded and unuseable.

A perfect example of solid state being used for massive amounts of read/write over a good period of time is the Eve-Online game cluster. Last year they upgraded the database, moving it over to RamSan-4000 solid state drives. (http://www.superssd.com/products/ramsan-400/indexb.htm). Being an MMO they get literally millions of small writes/reads/rewrites every day, and yet the DB server is still running good after a year of running solid state. So good in fact they have just invested in another, which given the cost you wouldnt do if the tech wasn't up to scratch.
