IBM last Friday announced that it will
release a low-price disk server aimed at midsize companies that want to
establish storage area networks.
The DS300 is based on iSCSI, a protocol that relies on existing Gigabit Ethernet networks and is therefore less expensive than traditional Fibre Channel-based storage area networks.
The server has Ultra320 iSCSI drives, battery backup cache and power supplies. The system will start at US$2,995, IBM said.
The release is significant, because storage hardware and software
companies have been trying to reduce cost barriers by making their
products affordable to small and midsize companies, in large part by embracing the iSCSI standard.
IBM also announced the DS400, a 2GB Fibre Channel storage system
that's 5.25 inches tall. That server will start at US$5,254, IBM said.
Both servers can be managed with RAID (redundant array of
independent disks) management tools, and both run on Windows and Linux,
IBM said. Both are part of Big Blue's TotalStorage suite and will be available in the fourth quarter.
Also last Friday, IBM changed the name of its midrange storage arrays
from FastT storage servers to DS4000 midrange disk systems, and
announced new software for the product line. Big Blue's DS4000 Storage
Manager V9.1 software is designed to protect information via real-time
data replication. The software lets customers mirror data both
synchronously and asynchronously. It is free to existing customers and
can be downloaded from the company's Web site.
In addition, IBM said its high-end Enterprise Storage Server
products--sometimes referred to as "Shark"--are now part what it is
calling the "IBM TotalStorage Disk Systems Family."
