What’s New?
The PowerVault™ MD3200i and MD3220i offer the following new features:
2X performance improvements over MD3000i
o Up to 800MB/s RAID5 sequential reads
o Up to 30K RAID5 random disk reads
Four models to choose from:
o A cost effective, high capacity model (MD3200i): Single controller with 2GB of battery
backed cache and four 1Gb Ethernet host ports housed in a 6Gb SAS 2U, 12 drive 3.5” HDD
enclosure. (directly connect up to 4 non –HA physical servers or up to 32 non-HA physical
servers with an Ethernet switch)
o A highly available, high capacity model (MD3200i): Dual active/active controllers with a
total of 4GB mirrored battery backed cache and a total of eight 1Gb Ethernet ports housed
in a 6Gb SAS 2U, 12 drive 3.5” HDD enclosure. (directly connect up to 8 non-HA physical
servers or 4 HA physical servers or up to 32 HA physical servers with Ethernet switches)
