Superior Data Solutions manufacturers
Tier 0 and Tier 1
Solid State storage solutions for the enterprise. Our FC enclosures incorporate
today's best of breed FC or SATA high performance, enterprise grade, flash solid
state drives while balancing overall performance with cost. SpeedStor, a direct
connect FC or SAN enclosure, incorporates the worlds' fastest flash disk
technology. SpeedStor offers access rates comparable to DRAM at a fraction of
the cost. FlashStor, a cached SATA to FC flash RAID, balances capacity,
performance and cost in order to offer a reasonable alternative to today's HDD
subsystems.

Data Solutions - editor mentions on STORAGEsearch.com
- editor's comments:- Superior Data Solutions manufactures fully integrated
SSD enclosures. They sell
to large OEMs (who self brand) as well as direct; under their SpeedStor and
FlashStor brands.
Their 1st enterprise SSD was developed in 2006 in
partnership with
Gnutek.
More
recently Sun Microsystems
has oemed SDS's
SpeedStor
- a 1U rackmount flash SSD which includes best of breed COTS
fibre-channel SSDs.
An important thing to bear in mind about the SpeedStor is it doesn't
have any internal RAID
protection. That's why the box looks superficially faster than some other flash
SSD rackmounts (which do have internal RAID) - for example from
EasyCo.
For
serious online server apps you may need to deploy multiple SpeedStors and wrap
data protection around the boxes - which could impact overall cost,
performance and complexity.
...Later:- November 24, 2008 -
Linda LaPorta at Superior Data Solutions confirmed my guesses above -
and said more about how customers use this product.
"The
SpeedStor is designed to target high IOP environments with concurrent access to
the same files (the more the better). In regards to RAID-Like protection; we
purposefully designed SpeedStor to have direct connections to the FC HBA in
order to ensure no additional latency. Furthermore, 2 or 3 drives will saturate
most controllers. Again, this is to take full advantage of the drive's
capability."
"For those whom require HA, we recommend host
based mirroring, as the CPU overhead is negligible (remember, we are not placing
entire databases on here). For instance, Sun places the metadata of SAMQFS onto
the SpeedStor, and mirrors with disksuite. Overhead was not worth noting
(.0003%). We do have customers who have designed very large high IOPs SSD
systems with multiple drives, each on their own FC port, striped in a RAID 5
configuration with QFS as well as ZFS. "
