Editor:- June 4,
2010 - I was curious to learn more about the internals of the UNAS 100 - Solid
Access's 1st flash SSD system - and asked Tomas Havrda, Managing
Partner for more info. He said that the internal interface is
SAS - an interface
with which I know they are very familiar - having shipped the world's 1st SAS
RAM SSD in 2005.
"After a search of almost 2 years, we partnered
with a Flash SSD vendor that provided the type of sustained, predictable
performance Solid Access required to bring an entry to market. This has always
been one of the major attributes of our DRAM SSD appliances and we needed to
find Flash technology that reasonably approximates this capability to continue
to project Solid Access's image as a high performance storage appliance vendor
offering products that will perform next month or next year the same way as
today.
"We were also equally concerned about
performance drop off
from Burst to Steady State mode and our selected vendor has the least
performance loss of the vendors we tested or have been able to obtain results
for." |

UNAS
100 (announced May 2010) |
Is a very fast 2U rackmount NAS SLC flash SSD -
with 2.4TB capacity, 96GB DRAM Cache, 2x 10GbE ports, 300,000 IOPS, 1,000MB/s
bandwidth and under 10 microseconds access time.
This is the 1st flash SSD system from Solid Access - which has been in
the RAM SSD market for 8 years. It includes many enterprise SSD reliability
features - and the flash modules are hot swappable and can be mirrored.

USSD 200 |
Universal Solid State Disk, USSD 200, is the
performance/price leader for enterprise SSDs. Capacity is upto 128GB in 2U,
and access time is under 10 microseconds. Random read/write performance
is 98,000 IOPS using a single Fibre Channel link and over 70,000 IOPS using SAS.
Upto 320,000 IOPS in a single 2U chassis. 3,600MB/s aggregated
bandwidth via 6 FC links.
Whether you want to conquer your I/O bottleneck problems once and for
all, increase your transaction handling capability, extend the useful life and
productivity of your legacy system, or go all the way and put your whole
database on silicon to run at RAM speed, you owe it to yourself to investigate
USSD.
Why? Because USSD guarantees cutting-edge performance at a fraction
of the cost of competitive enterprise solid state disks. The USSD disruptive
innovation stands alone with its multi-protocol access via
320MB/s SCSI,
4Gb/s Fibre Channel and even
3Gb/s SAS.
USSD prices
range from about $12,000 for a 16GB-SCSI 320MB/s unit to $50,000 for a
128GB-FC 4Gb/s or SAS unit.
We invite you to compare the performance and price of our USSD 200
with any storage device on the market today. The performance/price advantage of
USSD will astound you.
