Start of changeiSCSI attached servers are standard xSeries or IBM BladeCenter server models that have processors, memory, and expansion cards, but no disks. All of the disk space is in the iSeries™ server and managed in the same way as for IXS and IXA models.End of change

Start of changeThe installation procedure for an iSCSI attached integrated Windows server requires hardware to be installed and configured in the iSeries and xSeries or IBM BladeCenter servers. As in the IXA, the iSCSI HBA attached xSeries servers have their own expansion slots, so additional options can be installed to expand the capabilities of the server.End of change

  1. You need a compatible iSeries. See Hardware requirements for compatibility information.
  2. The i5/OS™ console, from which you connect to the iSeries using iSeries Navigator or the character-based interface, is shown to make clear the distinction between it and the Windows console.
  3. Depending on the type of the physical network, copper or fiber iSCSI HBAs are available. This iSCSI adapter serves as the target device and connects to an Ethernet network using standard Ethernet cables.
  4. An integrated server does not have its own hard disk drive. i5/OS emulates hard disk space for it to use from iSeries hard disk drive. These drives and other iSeries storage devices are accessed through the iSCSI HBA.
  5. The iSCSI HBA network cables are connected to a standard Gigabit Ethernet switch.
  6. An additional iSCSI HBA is required in the xSeries server. This adapter provides the connection to the iSCSI HBA for iSeries. This adapter can be viewed from the xSeries server as the storage adapter, where the disks are found across the network.
  7. A typical iSeries server will have a network card. An iSeries LAN connection is required by IBM Director to discover and manage the remote xSeries or IBM BladeCenterCenter servers.
  8. A service processor allows the iSeries server to discover and manage the remote system. The service processor may be a remote supervisor adapter (RSA II), a Baseboard Management Controller (BMC), or a Management Module of an IBM BladeCenter. The RSA II, BMC, or Management Module is connected to the iSeries server over an Ethernet network.
