The Hurricane 4 controller in each node in a complex consumes 256 MB of
the main memory by the embedded XceL4v dynamic server cache
technology, described in 1.6.2, "XceL4v dynamic server cache" on page 30.
After initialization of main memory, you see the amount of memory that is
consumed for XceL4 cache after a successful merging is completed.
All systems you integrate in a complex
RSA II, FPGA, BMC and BIOS.
Note: Our recommendation is to flash all the system components after you
install the ScaleXpander chip. We recommend you reflash these
components, even if the latest versions are already installed.
The UpdateXpress-based update packages do not allow the reflashing, if
the same level of code is installed already. In our lab, we used the
DOS-based update utilities to do this.
The RSA II network interface should be configured and attached to a
separate management LAN.
You must have access to at least one RSA II network connection to control or
configure your scalability configurations.
You can manage all partitions by the RSA Adapter II's scalability management
menu in any system in this complex.
We recommend that you connect the RSA II in each node to your
management LAN. This ensures that you can connect to the RSA II Web
interface of at least one node to manage the complex. This can be important if
you require assistance by your local IBM technical support if the system
experiences any hardware-related error.
Remember, the remote video and remote drive features are available from the
RSA II interface of the primary system only after a merge is completed.
The BIOS date and time settings should be adjusted to your local time
settings.
Note: We recommend synchronizing the system time and the RSA II in the
BIOS to be sure they have the same time stamp information for events that
can occur. See Figure 4-3 on page 204. You may also set up and use a
time server for the operating system and Remote Supervisor Adapter II.
Boot to System Setup (press F1 when prompted) and select Date and Time.
Figure 4-3 on page 204 appears.
