Using the RSA
The documentation CD-ROM that came with your system contains additional
information and software for the RSA.
To use the RSA, complete the following steps:
1. Consult the RSA user’s manual and the README file that is located on the
documentation CD-ROM.
2. Run the executable to create a bootable floppy disk. The executable is located
in:
C:\IBM\ASMP\UPDATES\33P2474.EXE
3. Boot each node of the NAS Gateway 300 with floppy disk created in the
previous step to configure the RSA.
Enabling Ethernet adapter teaming
This section describes how to enable adapter teaming on the Ethernet adapters.
Note: The integrated Ethernet controller on each NAS Gateway 300 node is
dedicated to the clustering interconnection between it and another node and
cannot be used for teaming.
The Ethernet adapters that you install in the PCI slots of the NAS Gateway 300
nodes support
adapter teaming (also known as load balancing). With adapter
teaming, two or more PCI Ethernet adapters can be physically connected to the
same IP subnetwork and then logically combined into an adapter team.
The NAS Gateway 300 uses two different Ethernet vendors, Intel (PRO/1000 XT
Server Adapter by Intel and IBM Gigabit Ethernet SX Server Adapter) and Alacritech
(Alacritech 1000x1 Single-Port Server and Storage Accelerated adapter and
Alacritech 100x4 Quad-Port Server Accelerated Adapter). Each vendor offers
different means of implementing teaming, and teaming cannot be done between
adapters of different vendors. There might also be restrictions on what functions are
supported with adapters from the same vendor.
Note: It is strongly recommended that you configure adapter teaming before you
set up Microsoft Cluster Server (MSCS) clustering, as described in
Chapter 5, “Completing networking, clustering, and storage access setup” on
page 33. Additionally, for each team that you configure on one node, you
must configure an identical team (same type of team, same set of adapters,
and so on) on the other node.
Alacritech Ethernet adapter teaming
Alacritech uses SLIC (Session-Layer Interface Card) technology, which incorporates
hardware assistance for TCP processing. Most, but not all, of the processing
overhead for TCP/IP is removed from the NAS engine. This is an optional feature
and can be disabled if required.
Alacritech offers four methods of teaming:
Cisco Fast EtherChannel (Fast EtherChannel and Gigabit EtherChannel
compatible)
Fast EtherChannel (FEC) is a proprietary technology developed by Cisco.
With FEC, you can create a team of two to four ports on an adapter to
increase transmission and reception throughput. The FEC might also be
