Coraid Has SATA Ethernet Drive
Accommodates Maximum of 7.5 Terabytes Storage

Coraid's EtherDrive Storage product is
now available for Serial ATA disk drives. In a move resulting from market
feedback and demand, the company has upgraded its EtherDrive Storage appliance
with a list of impressive features.
Coraid is offering what its calls "ultra reliable storage" that uses the AoE (ATA over
Ethernet) protocol, which it refers to as "the simplest, most efficient, and lowest cost means for
networked storage." Using Ethernet connections, EtherDrive Storage Blades appear
to servers on the network as locally attached disks. EtherDrive Storage can
easily be assembled into large RAID sets and storage volumes.
The refined chassis design includes
15 hot swap drive bays which accommodate standard SATA disk drives. The new
shelf offers a dual GigE Interface, redundant hot swap power modules and fans.
Fully populated drive bays using 400 GB disk drives yield 6 TB of storage, but
using 500 GB drives, the new Coraid shelf provides an impressive 7.5 TB of
Coraid’s PATA product, the new SATA platform provides extreme scalability.
Exceeding storage capacity proves nearly impossible as storage arrays are
limited only by physical rack space. The SATA EtherDrive shelf has dual GigE
connections, so storage array performance is fast and reliable, the company says. A single shelf
can provide 200MB of storage access throughput and because the AoE protocol is
so simple, almost any host can saturate its Ethernet connections to the storage
and still have CPU cycles left for the servers main
EtherDrive Storage is less expensive than any other
networked storage. Traditional fibre channel SAN’s are very expensive and can
prove cost prohibitive for many companies. Fibre channel requires a large
footprint, expensive fibre channel switches and complicated management software.
iSCSI is burdened with the processing of TCP/IP, creating bottlenecks. The price
of the new SATA EtherDrive Storage is only $3,995 Using 400 GB SATA disk drives
at their current price, a complete 6 TB shared storage solution can now be
assembled for $1.32/GB.
