New Directory - SAS SSDs

Editor:- January 26, 2009 - StorageSearch.com today published a new article and directory on the subject of SAS SSDs.

This market has been a long time acoming - and for many years there were only 1 or 2 vendors in the market. The new article chronicles the genesis of SAS SSDs and lists known vendors - which will head into double digits this year.


RamSan SSD Revenue Grew 20% in 2008

Houston, Texas - January 20, 2009 - Texas Memory Systems today announced that revenue from sales of its RamSan line of SSD products grew 20% in 2008.

The company also recorded record 4th quarter sales.

"We feared the global financial crisis and increasing competition would have a bigger impact on our 2008 results," said Woody Hutsell, Executive VP at TMS. "However, our solid state disks are often used in mission-critical applications and, in such applications, customers value Texas Memory Systems' engineering experience and 30-year longevity. Savvy IT managers will always be reluctant to put their critical data on a first generation product, whether it comes from a Fortune 500 company or a venture-funded startup."

"We are cautiously optimistic about 2009," continued Mr. Hutsell. "Solid state disks are an important part of modern telecommunications systems, financial exchanges, national defense systems and 'green IT' initiatives which are likely to benefit from new government investment. Additionally, a solid state disk can cost-effectively extend the life of existing IT infrastructure allowing cash-strapped IT managers to postpone major purchases." ...Texas Memory Systems profile

Editor's comments:-
while 20% annual revenue growth is indeed impressive - it nevertheless represents a slow down for TMS, which in some earlier years had reported growth rates between 45% and 80%.

One factor may be that in the past year the server acceleration market has become very competitive. Nearly 30 oems market rackmount SSDs - and if you add in the SSD speedsters from the 2.5" and PCI Express SSD markets you'll easily tot up more than 40 companies seriously competing in the space where Texas Memory Systems operates. Given those factors - and the recession - 20% revenue growth for TMS indicates a strong brand and product line.

In my article - Is the SSD Market Recession-Proof? (published July 2008) - I said "Overall a recession will be good for vendors of faster server oriented SSDs (both flash and RAM based) - but a recession will be bad for vendors of notebook SSDs." My many recent discussions with SSD vendors (and the press release from TMS today) seem to confirm this.

Anticipating that their web site would get slammed by viewers - the CTO turned to a VAR who suggested they install a fast RAM SSD - the RamSan-400 to quickly upgrade their server performance.


Solid Access Launches World's Fastest 1U Rackmount SSD

Austin, TX - November 17, 2008 - At SC08 today Solid Access Technologies announced the immediate availability of its new generation of DRAM SSD products, the USSD Series 300.

Solid Access says the 4 new models are aimed at organizations requiring the highest capacity, "no compromises" IOPS and data bandwidth performance in the smallest possible footprint. Interface options within the family include 8Gbps Fibre Channel, 6Gbps SAS and 320MB/s LVD SCSI interfaces. R/W latency is under 10 microseconds and the models support upto 100K IOPS on a single port.
  • Model 310 is a 256GB, 1U rackmount offering for high IOPS needs
  • Model 310T is a 1TB, 4U tower, targeted at high performance databases
  • Model 315 is a combined server and 128GB RAM SSD, 1U device, for custom projects
  • Model 320, a 256GB, 2U product which supports upto 6 ports and 4GB/s sustained aggregated data bandwidth.
Solid Access says it guarantees equivalent or better application I/O acceleration as well as the lowest price of any comparable SSD, and has launched a "test before you buy" program.

"Five years ago when we introduced the first open architecture, ultra-fast DRAM SSD, our goal was to offer the best performance, most flexible interfacing, highest density and best price of any offering in the segment" said Tomas Havrda, Solid Access Managing Director. "The new USSD 300 Series is the capstone to our efforts in a year in which we have enjoyed 500% growth. The recent 28 unit USSD sale to Samsung Securities is further proof that customers of all sizes are taking notice." ...Solid Access Technologies profile

Editor's comments:-
for several years there has been a gap in the market for a really high performance 1U rackmount SSD. My gut feeling is it could become a very popular form factor in Google style (democratic) server architectures - which contain large numbers of identical servers..

As the cost of RAM SSDs easily makes them the most expensive box per rackmount unit in the datacenter - the availability of 1U models reduces the incremental deployment costs for customers who are continuously upgrading their systems. It also lowers the cost of holding immediately deployable spares.


Dataram Re-enters the SSD Accelerator Market

Redding, CA - October 8, 2008 - it was announced today that Dataram Corp has acquired the strategic assets of Cenatek, Inc.

"I am very pleased that we have successfully completed this transaction," said Jason Caulkins, CEO of Cenatek. "Dataram is providing significant resources to build upon the Cenatek product line, roadmap and IP portfolio."

"This acquisition signifies the beginning of a series of focused efforts to move Dataram into new, growing markets that align well with Dataram's existing products and customer base," said John Freeman, President and CEO of Dataram. "We are moving very quickly to license, acquire and develop these new products, including software, into our customer-focused product lineup."

Caulkins has joined Dataram to lead the company's return to solid state storage, an area they pioneered 32 years ago. "I am looking forward to contributing to the continued growth and success of Dataram," Caulkins added. "I would also like to thank Cenatek's investors and employees for their hard work and commitment to success." ...Dataram profile, ...Cenatek profile, RAM based SSDs

Editor's comments:- this is a very significant milestone for the SSD market because it shows the strategic value that memory makers place on SSDs.

In the past companies like Intel have resold 3rd party SSD cards, STEC divested itself of its vanilla memory business and Samsung would like to own and control MLC patents now in the hands of SanDisk.

Look at it from the viewpoint of a memory maker.

Future server systems will have orders of magnitude more memory in the attached SSDs than installed as main RAM memory. Who owns the brand of the SSD boxes will mean a dramatic difference to attainable revenue. Being locked out of the SSD box - will mean that a memory maker can only access smaller markets - or supply other SSD oems at commodity proces. I expect to report many more such acquisitions during the next few years.

...Later:- when discussing this story my wife said this is an example of a marketing concept called "forward integration."

When flash SSDs aren't fast enough!

RAM based SSDs
are the original type of solid state disk and have been around for decades.

They rely on batteries to retain data when power is lost. Most models also include internal hard disk drives to which data is saved under battery power, so that data is not lost when the battery runs down. This hybrid technology means that RAM based SSDs are more bulky than flash counterparts and RAM SSDs are unable to operate in the same range of hostile environments.

RAM based SSDs are mostly used in enterprise server speedup applications. The fastest RAM SSDs are faster than the fastest flash SSDs. But for many server speedup applications F-SSDs are fast enough.

Unlike flash SSDs, RAM based SSDs never had restrictions on the number of write cycles. That made them more popular in enterprise acceleration applications in the past. But write endurance problems may be a thing of the past for flash.

Like hard disks - RAM SSDs have symmetric read/write IOPS. That's another big difference between RAM and flash SSDs.

The fastest flash SSDs available in 2007 had narrowed the gap between read/write IOPS down to 10 to 1. (RAM SSDs are 1 to 1 and earlier flash SSDs were 50 to 1.)

In the next few years that gap could close even more.

There are also some non volatile memory products which are replacing flash in industrial applications - and which already offer 1 to 1 read/write performance. But their capacity is 2 orders of magnitude too low to be of use in server applications.

RAM SSDs cost about 25x as much as flash SSDs (based on pricing data for 3.5" form factor February 2008.)

The ideal choice of SSD depends on the specific server and application environment and cost / benefit analysis.

For example - a fibre-channel SSD that doubles the performance of a 100 server network may be overkill if your application runs on a single server box which could be speeded up by directly attached SSD storage.

SSD Myths and Legends - "write endurance"
Does the fatal gene of "write endurance" built into flash solid state disks prevent their deployment in intensive server acceleration applications - such as RAID systems?
It was certainly true as little as a few years ago.

What's the risk with today's devices?

This article looks at the current generation of products and calculates how much (or how little) you should be worried.
read the article - SSD Myths and Legends
RAM based SSDs have been used alongside RAID for years - but flash SSDs are physically smaller and have bigger capacity (upto 412G in 2.5", 512G in 3.5") and are lower cost than RAM-SSDs and could actually be configured in standard RAID boxes. F-SSDs aren't as fast as RAM based products but a single flash SSD can deliver 20,000 IOPs - which when scaled up in an array - starts to look interesting. ...read the article, storage reliability solid state disks
