The EXP5060 is a 4U rack-mountable enclosure that supports up to 60 SATA Disk Drive
Modules (DDMs), offering up to 60 TB of SATA disk space per enclosure using 1 TB SATA
DDMs. The expansion enclosure contains 60 drive bays (arranged on five stacked drawers
with twelve drives for each drawer), dual-switched 4 Gbps ESMs, and dual power supplies
and cooling components. Coupled with a storage subsystem (DS5100 or DS5300), you can
configure RAID-protected storage solutions of up to 480 TB when using 1 TB SATA DDMs
and eight EXP5060 storage expansion enclosures, providing economical and scalable
storage for your rapidly growing application needs. The Attach up to 8 EXP5060s feature pack
must be purchased for the DS5100/DS5300 storage subsystem to enable it to be connected
to up to eight EXP5060 storage expansion enclosures.
2.7 iSCSI host interface
The DS5000 storage subsystems support 1 Gbps iSCSI connectivity. You must determine
how the host systems will connect to the storage subsystem.
The iSCSI ports support IPv4 and IPv6 TCP/IP addresses, CHAP, and iSNS. Use either
Cat5E or Cat6 Ethernet cable types for iSCSI port connections. A Cat6 Ethernet cable
provides optimal performance.
iSCSI host interface cards (HICs) are only an option when initially purchasing the IBM
DS5020. iSCSI HICs for the DS53100 and DS5300 are available as field replacable upgrades
(MES) that will be installed by trained IBM service personnel.
See Chapter 3, “IBM System Storage DS4000 and DS5000 hardware” on page 23 for specific
information about iSCSI on a particular DS5000 subsystem.
2.8 8 Gbps FC host interface
The DS5000 offers 8 Gbps Fibre Channel (FC) host attachment. Upon purchase of the
DS5000, you must determine how many host ports you will need.
The DS5100 and DS5300 storage subsystems are field upgradable to 8 Gbps by installing the
quad-port HIC.
There are up to four (two per controller) quad-port 8 Gbps FC host interface cards (HICs)
available per DS5100 and DS5300 storage subsystem. They will be installed in pairs of two
(one in each controller).
A DS5020 storage subsystem is not upgradable. Host attachment must be ordered with the
initial purchase of the DS5020.
2.9 16 port host port upgrade for the DS5100
Initially, the DS5100 storage subsystem supports only one host interface card (HIC) per
controller. That limits the number of host attachment ports to a maximum of eight. Starting
with firmware 7.50, the DS5100 allows a second HIC card to be installed into each controller
to extend the number of host ports to 16 (eight per controller). No premium feature is
required.
