DS4700特性
Model – 72 and 70
RAID Controller
Dual RAID controllers – Dual 4Gbps capable, redundant and hot-swappable, battery backed, write cache mirroring
Model 70A supports 2GB cache - battery backed cache is designed to be protected for at least three days
Model 72A supports 4GB cache - battery backed cache is designed to be protected for at least three days
Supporting 2 dual redundant FC disk loops
Model 70A Supports four host side and four drive side ports for two controllers
Model 72A Supports eight host side and four drive side ports for two controllers
Eight or four host ports provides a cluster solution without using a switch.
Host Interface
Auto negotiates 1, 2, or 4 Gbps host connection speeds
Supported drives
2Gbps FC: 10K rpm, 73GB/146GB/300GB (E-DDM)
4Gbps FC: 15K rpm, 73GB/146GB/300GB (E-DDM)
SATA: rpm 500GB /750GB (E-DDM)
Hot pluggable drives - Add new drives for extra capacity without booting server
Supported capacity
Supports up to 112 FC/SATA drives with 6 DS4000 EXP810 Expansion Unit’s
RAID levels
0, 1, 3, 5,
