—Adding to its Dell/EMC AX150i line of iSCSI disk arrays (and causing a bit of confusion over the relative positioning of its IP SAN arrays), Dell this week introduced the iSCSI-based MD3000i.
Steve Arrington, PowerVault product manager at Dell, says that many vendors have brought iSCSI products to market but they are usually scaled-down models lacking some features of their more expensive products.
The MP3000i is available in single-controller or dual active/active controller versions supporting up to four Gigabit Ethernet connections and up to 15 3.5-inch Serial Attached SCSI (SAS) disk drives (10,000rpm or 15,000rpm) in capacities of up to 400GB. Maximum capacity is 18TB with two expansion enclosures and a total of 45 SAS drives.
The disk array includes multi-path software for failover, as well as optional data protection features such as Virtual Disk Snapshots (up to four snapshots per virtual disk or 128 snapshots per system) and Virtual Disk Copy (up to eight simultaneous copies).
In the fourth quarter, Dell plans to add support for SATA drives in capacities from 250GB to 1TB, with the ability to mix SATA and SAS drives in the same enclosure.
The MD 3000i supports RAID 0, 1, 5, and 10, with up to 30 physical disks per disk group and up to 256 virtual disks. Each controller comes with 512MB of cache memory.
The iSCSI array supports Windows 2003 and Linux, including RedHat 4.0 and SUSE.
Dell considers LeftHand and EqualLogic to be its main competitors.
Pricing for the MD3000i ranges from $8,000 to $20,000.
