VNX5400 product description
◆ One 3U DPE:
• On the front of the VNX5400, the 3U DPE (Figure 2 on page 8) has two SPs (SP A
and B). Each SP consists of:
– One disk drive carrier type; the 3U, 25 (2.5-inch) disk drive carrier (Figure 3 on
page 15). Two types of disk drives are supported in this carrier: Serial
attached-SCSI (SAS) and Flash
– Four dual cooling fan packs (see “Storage processor dual fan pack (cooling
module)” on page 14 for more information) or packs (eight fans total)
Note: The dual cooling fan pack is secured with push-tabs on the left and right
sides of each pack.
– One CPU module with an Intel Xeon 4-core 1.8-GHz processor facilitating
Simultaneous Multi-Threading (SMT).
– Eight Double Data Rate Three (DDR3) synchronous dynamic RAM (SDRAM) slots
supporting up to 16 GB of SDRAM per CPU module or SP using 4 or 8 GB DIMMs
– Three LEDs; power on, fault, and unsafe to remove
Note: Each CPU is secured with a push tab/pop out latch.
• On the rear of the VNX5400, the 3U DPE (Figure 2 on page 8) has two SPs (SP A and
B). Each SP consists of:
– One battery backup unit (BBU) providing back-up power for the SP and the disk
drives allowing for the flushing (data cacheing) of the vault drives whenever an
AC or DC input power loss to the storage system occurs (see “Battery backup
unit” on page 26 for more information).
Note: The BBU module is secured with a push-pull type of latch.
– One base module featuring two integrated 4x lane 6-Gb/s mini-SAS HD
(encryption capable) back-end ports (labeled 1 and 0, respectively).
Note: The base module is secured with a screw-type of latch (see “Base
module” on page 26 for more information).
– One management module (see “Storage processor management module” on
page page 32 for more information) featuring:
a.) One RS-232/EIA 232 serial (up to 115 K baud) service laptop (micro DB-9)
port
b.) One RS-232/EIA 232 serial SPS management (micro DB-9) port
c.) One 10/100/1000 LAN network management (RJ-45) port
d.) One 10/100/1000 LAN service (RJ-45) port
Note: The management module is secured with a latch handle (labeled MGMT).
