Coraid on Wednesday introduced the EtherDrive SR2421 Storage Appliance. The rack-mountable storage system contains a hardware RAID controller and space for 24 Serial ATA (SATA) disks and costs $4,995 (without storage).
The two dozen slots for drives can each accommodate a 1 terabyte (TB) drive mechanism, for a combined storage capacity of 24TB. It supports RAID levels 0, 1, 5 and 10, and can also be used as a JBOD (Just a Bunch Of Disks). The shelf is equipped with a universal power supply, and it's shipped on standard cabinet-mount slide-out rails. It's designed to fit in equipment cabinets with a depth of 28 to 33 inches.
The SR2421 is designed to be a self-contained storage area network device. It includes Coraid firmware running on an embedded Plan9 OS. Operating system support includes Mac OS X, Linux, FreeBSD, Solaris and Windows.
