.SAN design reference guide Vol. 1-5 785350-001

The following examples show maximum configurations for initiator/target pairs:
• 500 iSCSI initiators, each connecting to one target (storage controller port)
• 100 iSCSI initiators, each connecting to five targets
• 50 iSCSI initiators, each connecting to eight targets and 100 iSCSI initiators, each connecting
to one target
The maximum of 500 TCP connections (initiator/target pairs) with 256 LUNs per connection yields
128,000 possible LUNs. Simultaneous access to 128,000 LUNs via a single 100 Mb Ethernet
port may provide reduced performance.
The total bandwidth required for an Ethernet port for iSCSI storage should be based on the sum
of the individual requirements for each connection.
HP ProLiant Storage Server iSCSI Feature Pack

• “Sample iSCSI NAS Microsoft Exchange Server 2003 configuration” (page 364)
Overview
HP ProLiant Storage Servers can be configured as iSCSI targets using the HP ProLiant Storage
Server iSCSI Feature Pack.
The HP iSCSI storage server solution facilitates centralized management, backup, and scalability
by integrating services for:
• Files
• Printing
• Email
• Databases
Existing Ethernet infrastructure provides low-cost storage consolidation.
The HP iSCSI Feature Pack (T3669A only) includes the HP ProLiant Application Storage Manager,
which provides storage management for HP NAS servers hosting Microsoft Exchange 2003 storage
groups. It reduces the time and training required to set up and monitor email stores.
The HP iSCSI storage server is ideal for businesses that want to consolidate storage and that use
applications such as Microsoft Exchange.
