General Best Practices

Follow these general best practices for installing and configuring the HBA:

  • Spread the I/O load among multiple HBAs and multiple ports to avoid bottlenecks and promote higher availability.

  • Use fixed link speeds instead of autonegotiation wherever possible. While the HBA supports autonegotiation, autonegotiation slows the system down in the event of a fabric rebuild.

  • Do not configure both tape devices and disks on the same HBA port, even if using a switch and zoning.

  • If more than one HBA model is present in the configuration, enable only the OptionROM (OpROM) for the first HBA seen in the boot sequence. There is a limited amount of space for OpROMs; therefore, do not unnecessarily enable all OpROMs, as space usage issues might occur.

  • When installing the HBA, be sure to also install the latest version of the command-line utility available from the manufacturer web site (see Installing a CLI for Updating the BIOS and Firmware). Keep the HBA utilities, firmware, and drivers up-to-date, and update them in that order.
