The factory default setting for a CX-Series SP is 2 Gbits and for an FC4700-2 SP is 1 Gbit The speed of each port on a CX-Series or FC4700-2 SP can be set individually using Navisphere Manager or CLI. Switch Port Speeds The speed (auto-negotiate, 1 Gbit, or 2 Gbit) of the each port on a DS-16B2, DS-24M2, or DS-32B2 switch can be set individually. The default speed of each port is auto-negotiate. If a switch port is connected to an LP7000 HBA port, the switch port's speed must be set to match the speed (1 Gbit or 2 Gbit) of the HBA port. For example, if you connect an LP7000 HBA to a 2-Gbit switch port, you must set the switch port's speed to 1 Gbit. Clustered Server Configuration Rules Clustering software is required whenever multiple servers running the same operating system are connected to the same storage system (non-Access Logix) or to the same Storage Group (Access Logix). The servers must be part of the same cluster. Number of Nodes See the CLARiiON sections in the EMC Support Matrix. Supported Operating Systems All. Note clustering is not currently supported on a Linux server running PowerPath. Number of HBA Ports The number of HBA ports depends on the operating system and the failover software on the server. For information on the failover software supported for a particular operating systems, see the Failover Configuration Rules section later on this page. For PowerPath - 2 or more per server, except for Linux, which can have only 1 per server, and NetWare, Windows 2000, and Windows NT servers, which can have 1 or more. For PowerPath Base - 1 or 2 per server, except for Linux, which must have only 1 per server. For ATF - 2 per server, except for IRIX, NetWare, Windows 2000, and Windows NT servers, which can have 1 to 2 HBA ports. Note: Oracle9iRAC for Windows 2000 requires 2 HBA ports. If a Windows 2000 or Windows NT server running MicroSoft Cluster Server is connected to a storage system containing the boot device, it must have 2 HBA ports: 1 for the boot device and 1 for cluster services. HBA-Port Types HBA ports from the same HBA vendor, server bus type, and Fibre Channel link speed are required for each path to a storage system. Document Rev 19 Page 14 EMC Confidential

Port Speed Rules
Storage-System SP Port Speed
The speed of each port on a CX-Series or FC4700-2 SP can be set individually using Navisphere Manager or CLI.
Switch Port Speeds
The speed (auto-negotiate, 1 Gbit, or 2 Gbit) of the each port on a DS-16B2, DS-24M2, or DS-32B2 switch can be set
individually. The default speed of each port is auto-negotiate. If a switch port is connected to
an LP7000 HBA port,
the switch port
’
s speed must be set to match the speed (1 Gbit or 2 Gbit) of the HBA port. For example, if you
connect an LP7000 HBA to a 2-Gbit switch port, you must set the switch port
’
s speed to 1 Gbit.
Clustered Server Configuration Rules
Clustering software is required whenever multiple servers running the same operating system are connected to the
same storage system (non-Access Logix) or to the same Storage Group (Access Logix). The servers must be part of
the same cluster.
Number of Nodes
See the CLARiiON sections in the
EMC Support Matrix
.
Supported Operating Systems
All. Note clustering is not currently supported on a Linux server running PowerPath.
Number of HBA Ports
The number of HBA ports depends on the operating system and the failover software on the server. For
information on the failover software supported for a particular operating systems, see the
Failover Configuration
Rules
section later on this page.
For PowerPath - 2 or more per server, except for Linux, which can have only 1 per server, and NetWare, Windows
2000, and Windows NT servers, which can have 1 or more.
For PowerPath Base - 1 or 2 per server, except for Linux, which must have only 1 per server.
For ATF - 2 per server, except for IRIX, NetWare, Windows 2000, and Windows NT servers, which can have 1 to 2
HBA ports.
Note: Oracle9iRAC for Windows 2000 requires 2 HBA ports. If a Windows 2000 or Windows NT server running
MicroSoft Cluster Server is connected to a storage system containing the boot device, it must have 2 HBA ports: 1
for the boot device and 1 for cluster services.
HBA-Port Types
HBA ports from the same HBA vendor, server bus type, and Fibre Channel link speed are required for each path to
a storage system.
