Dot Hill: High-Density Fibre Channel Or SAS Arrays
Dot Hill Systems, Carlsbad, Calif., recently started shipping a new family of 2U RAID arrays with a capacity of up to 24 2.5-inch small-form-factor hard drives or solid state disk drives.
Dot Hill's new 2722 4-Gbps Fibre Channel array and 2522 SAS arrays include intelligent, fully redundant controllers with optional support for the company's AssuredSnap snapshot and AssuredCopy volume copy data protection software modules.
Expansion is also possible with the addition of a 2U, 24-bay 2122 non-RAID SAS unit.
The 2272 and 2522 support a maximum of 96 SAS drives for a total capacity of 28.8 TB. Both offer performance of up to 230,000 input/output operations per second (IOPS), which is 30 percent faster than the previous generation. They also use 80 percent-plus efficient power supplies to cut power consumption.
Dot Hill's 2722 Fibre Channel storage arrays are already shipping, while the 2522 SAS arrays are expected to be generally available in April. List-pricing starts at under $16,000 for a fully populated 3.5-TB SAS drive system.
Future versions featuring 8-Gbps Fibre Channel or 6-Gbit SAS controllers are planned for the near future.
