|Several IBM servers are supported for running PSSP 3.4. Each |one can be within a standard SP system, in which case it is called an |SP-attached server, or it can be part of a system of clustered |enterprise servers. These terms signify the system configurations |in which a supported server participates when it runs the PSSP |software. |Except where otherwise noted, statements in this book about |function on SP nodes apply to all nodes that are running PSSP, regardless of |the physical system configuration in which they participate.
|SP-attached servers are stand-alone servers that attach to the SP control |workstation. They can also have a switch attachment in an SP system |that uses a switch. Clustered enterprise servers can be in a computer |system that is independent of the SP system, comprised of a control |workstation running the PSSP 3.4 software and connected to each of up |to 32 of those servers supported for running the PSSP software.
|Generally speaking from a switch administration point of view, these nodes |are fully functional with the SP Switch or the SP Switch2. This means, |they usually function just like any SP node mounted in an SP frame. |However there are some constraints to keep in mind regarding a server: |
