Host configuration overview
You must configure the hosts connected to the appliance to ensure proper communication. To
configure the hosts:
1. Install the HBA driver for the operating system running on the host.
2. Set the execution throttle of the HBA driver for proper load balancing. See “Using
execution throttles” on page 58 for more information.
The appliance supports the following HBAs:
■ QLogic (for Windows 2000/NT/Server 2003, Linux, Netware, RedHat, and Solaris)
■ HP fiber card (for HP-UX)
■ Emulex (for Windows 2000/NT/Server 2003, IBM-AIX, RedHat, Solaris)
If the customer purchased HP StorageWorks Auto Path for host-based failover support, you
must install this software on each host. See “Installing HP StorageWorks Auto Path” on
page 55 for more information.
To optimize appliance performance, HP recommends the following maximum number of host
connections:
■ 30 dual-HBA hosts with switches
■ 6 dual-HBA hosts without switches
The appliance supports these logical unit number (LUN) limits:
■ 4,096 virtual LUNs
■ 256 LUNs mapped through a node target port per host
