4 Storage Center 5.5 System Manager User Guide
Introduction
iSCSI Card – Enhanced 10Gb Support
This release provides 10Gb iSCSI support for additional network interface, switches, and
server operating systems beyond what was available in the previous release, including
support for the Chelsio S320E-CR (PCIe based) adapter. This is a dual-port IO card utilizing
the Chelsio T3 (terminator 3) ASIC for 10 Gb offload processing.
IO Card Change Wizard
The new IO Card Change Wizard provides a user interface within the Storage Center
System Manager to the utility used to map hardware changes to existing configurations.
The wizard can be used for IO card upgrades and removals or when upgrading controllers.
For more information, see Storage Center 5.4 I/O Change Wizard, document number
685-001-001 available through Dell Support Services.
Storage Center 5.3
iSCSI Card – Limited 10 Gigabit Support
This release introduces limited support for the Chelsio S320E-CR 10Gbps iSCSI card.
Configure Operational Mode
Legacy and Virtual Port operational mode can be selected during initial system setup for a
new Storage Center when Virtual Ports are licensed. This feature is described in the
Storage Center System Setup Guide, document number 680-022-007. After initial system
setup, ports can be configured within Storage Center Manager by using the Configure
Local Ports wizard.
Configure Local Ports Wizard
The redesigned Configure Local Ports wizard combines Legacy and Virtual Port
configuration in a single wizard. The Configure Local Ports screen displays a list of
controllers, slots, and ports present on the Storage Center. For each IO card and port used
on each controller, you can specify a network value of front end or back end and a usage
of primary or reserved.
iSCSI Qualified Names (IQNs)
In previous releases, servers were created using WorldWide Names (WWNs) for HBAs.
Users now have a choice when creating servers — WWN or iSCSI Name. The default is
iSCSI Name. For server ports, the iSCSI name is a user-defined string that might follow the
conventional iSCSI Qualified Name (IQN) format, but does not have to, and is intended to
be globally unique. The Storage Center does not impose the IQN format for servers and
enforces uniqueness only within a single Storage Center system.
Storage Center 5.2.2
Server Cluster
Storage Center 5.2.2 enables the selection of volumes to be promoted to a server cluster
when creating the cluster. Previously, all volumes mapped to server nodes were
automatically promoted to the Server Cluster. Once a volume is mapped to a Server
Cluster, it can be demoted from the Server Cluster to a server node. When a volume is
mapped to a server node, it can be promoted to a Server Cluster.
