MD3060e Dense Enclosure
EBOD expansion enclosure designed for use with the MD3 dense array series only (MD3260i, MD3460, MD3860i, MD3860f)

Dimensions are identical to the dense array series (MD3260i, MD3460, MD3860i, MD3860f)

Controllers on the MD3 dense series arrays have either one 6Gbps SAS Out port (MD3260i) or one 12Gbps SAS Out port (MD3460, MD3860i, and MD3860f) for connecting to the MD3060e enclosure expansion for additional capacity (max 2 per dense array). For systems without premium feature activation, the physical disk limit is 120.

MD3060e contains two hot-swappable enclosure management modules (EMMs)

Connectivity

Hot-swappable controllers
MD34x0 and MD38x0x controllers are not compatible with the older generation arrays (MD32x0x and MD36x0x).

Single controller models:
MD3400/MD3420: Directly connect up to two high-availability (HA)-configured servers or eight non-HA-configured servers to a single?MD3400 or MD3420 storage system. Available with 4GB cache controllers.

Dual controller models:
MD3400/MD3420/MD3460:?Directly connect up to four HA-configured servers or eight non-HA-configured servers to a single SAS storage system. Available with an option of 4GB or 8GB cache controllers.

MD3060e contains two hot-swappable enclosure management modules (EMMs)

Controller features
Each controller provides four 12Gbps SAS ports (MD3400/MD3420/MD3460); a total of eight for dual controller models
Each controller contains 4GB or 8GB of battery-backed cache
Dual controllers operate in an active-active environment mirroring each other’s cache
Cache protection is provided via flash memory for permanent data protection
Dynamic Disk Pools (DDP)* eliminates the need for complex RAID management while optimizing data protection, and can be used with existing RAID configurations
Dual controllers are required for the MD3460 dense array

RAID
Support for RAID levels 0, 1, 10, 5, 6
Up to 180/192* physical disks per group in RAID 0, 10
Up to 30 physical disks per group in RAID 5, 6
Up to 512 virtual disks
