The
RAID
Each
With two or hard drives per blade, the following RAID configurations are supported:
•RAID 0 (Data Striping): this writes data in parallel, interleaved (“striped”) sections on two hard drives. Data transfer rate is doubled over using a single disk.
•RAID1 (Data Mirroring): an identical data image from one drive is copied to another drive. The second drive must be the same size or larger than the first drive.
•Enhanced RAID 5 or RAID 10 (Data Mirroring): as RAID1 with data mirrored from one or more disks to one or more disks of a second, larger size. You can couple the disks from the source to create a virtual volume and use one or more disks of a second, larger size to provide a single larger volume (or multiple larger volumes) that serve as the mirroring drive or drives for the array.
Density
A maximum of ten blade modules may be installed into a single blade enclosure. Each blade enclosure is a 7U form factor, so a standard 42U rack may accommodate up to six enclosures with 60 blade modules, or the equivalent of 60 1U servers. With the inclusion of six CMM modules, twelve Gigabit Ethernet switches and six InfiniBand switches, this would occupy up to 84U space in a conventional 1U server configuration.
