Specifications

For fibre-channel attachments, IBM recommends that you establish zones. The
zones should contain a single port attached to a host adapter with the desired
number of ports attached to the ESS. By establishing zones, you reduce the
possibility of interactions between host adapters in switched configurations. You can
establish the zones by using either of two zoning methods:
v Port number
v Worldwide port name (WWPN)
You can configure ports that are attached to the ESS in more than one zone. This
enables multiple host adapters to share access to the ESS fibre-channel ports.
Shared access to an ESS fibre-channel port might be from host platforms that
support a combination of bus adapter types and the operating systems.
For information about host systems, operating system levels, host bus adapters,
cables, and fabric support that IBM supports, see the following Web site:

SCSI-attached open-systems hosts
An ESS attaches to open-systems hosts with two-port SCSI adapters. SCSI ports
are 2-byte wide, differential, fast-20. With SCSI adapters the ESS supports:
v A maximum of 15 targets per SCSI adapter
v A maximum of 64 logical units per target, depending on host type
v A maximum of 512 SCSI-FCP host log or SCSI-3 initiators per ESS
The ESS supports the following host systems for SCSI attachment:
v Compaq AlphaServer with the Tru64 UNIX and OpenVMS operating systems
v Data General with the DG/UX operating system
v Hewlett-Packard with the HP-UX operating system
v IBM AS/400 and the IBM ERserver iSeries 400 (iSeries) with the IBM Operating
System/400
®
(OS/400
®
)
v IBM RS/6000
®
, IBM Eserver pSeries (pSeries), RS/6000 SP, and pSeries SP
with the IBM AIX
®
operating system
v IBM NUMA-Q and the IBM Eserver xSeries (xSeries) with the IBM ptx operating
system
v Intel based servers and, Linux operating system that runs Red Hat 7.1 and SuSE
7.2
v Intel-based servers with the Microsoft Windows NT
®
operating system
v Intel-based servers with the Microsoft Windows 2000 operating system
v Intel-based servers with the Novell NetWare operating system
v Sun with the Solaris operating system
See the following ESS Web site for details about types, models, adapters, and the
operating systems that the ESS supports for SCSI-attached host systems:

Fibre-channel (SCSI-FCP) attached open-systems hosts
Each ESS fibre-channel adapter has one port. You can configure the port to operate
with the SCSI-FCP upper layer protocol. Shortwave adapters are available on ESS
Models E10 and E20. Longwave adapter types and shortwave adapter types are
available on Models F10 and F20.
