Chapter 3. SGI RAID for CXFS Clusters

This chapter discusses SGI RAID for CXFS clusters:

For additional updates, see the CXFS release notes.

RAID Hardware

CXFS supports the following RAID hardware:

SGI InfiniteStorage 10000
SGI InfiniteStorage 6700
SGI InfiniteStorage 4500
SGI InfiniteStorage 4000
SGI InfiniteStorage 220 (Fibre Channel)
SGI RM610
SGI RM660
SGI TP9700
SGI TP9500S (serial ATA)
SGI TP9500
SGI TP9400
SGI TP9300S (serial ATA)
SGI TP9300
SGI TP9100
SGI S330

The SGI RAID will be initially installed and configured by SGI personnel.

RAID Firmware

SGI RAID supports the following firmware:

Note: SGI InfiniteStorage 220 does not support online updates of the controller firmware.

  • SGI RM610 and RM660 running version 5.12b or later.

  • SGI InfiniteStorage 6700 supports controller firmware version V3.00.

  • The TP9700 9.14 CD contains the required controller firmware and NVSRAM files. The 06.14.xx.xx code or later must be installed.

  • The TP9500S 8.0 CD contains the required controller firmware and NVSRAM files. The 05.41.xx.xx code or later must be installed.

  • The TP9400/TP9500 6.0 CD contains the required controller firmware and NVSRAM files. The 05.30.xx.xx code or later must be installed.

  • The TP9400 4.0 CD contains the required controller firmware and NVSRAM files for the 4774 or 4884 units:

    • If you have a 4774 unit, the 04.01.xx.xx , 04.02.xx.xx, or 05.30.xx.xx code or later must be installed

    • If you have a 4884 unit, the 04.02. xx.xx code is installed by default

  • The TP9300S 8.0 CD contains the required controller firmware and NVSRAM files. The 05.41.xx.xx code or later must be installed if using 2882 controllers, or 05.42.xx.xx code or later if using 2822 controllers.

    Note: The initial TP9300S used 2882 controllers in the controller module. This product was later replaced with a 2822 controllers (still using the TP9300S marketing code). With the release of the 2822 controller, SATA disk drives can be installed in the controller module (the 2882 did not have disk drives installed in the controller module).

  • The TP9300 7.0 CD contains the required controller firmware and NVSRAM files. The 05.33.xx.xx code or later must be installed.

  • The TP9100 4.0 CD contains the required version 7.75 controller firmware for the 1-Gbit TP9100. Supported via special request with optical attach (other conditions may apply).

  • The TP9100 5.0 CD contains the required version 8.40 firmware for the 2-Gbit TP9100.

    Note: The TP9100 is limited to 64 host connections.

  • The TP9300 8.42 CD (TPSSM 8.42) contains the required 8.42 firmware for the S330.

Number of LUNs Supported

By default, the RAID firmware supports a maximum number of logical units (LUNs). If additional LUNs are required, you must obtain a separate software-enabling key; this key will support a larger number of LUNs in separate partitions, which requires that the Fibre Channel ports be mapped to a partition. Contact your SGI sales representative for the SGI software partitioning key.

The maximum depends upon the code installed, as shown in Table 3-1.

RAID Verification

To verify that the SGI RAID is properly installed and ready for use with CXFS, you can dump the RAID's profile and verify the controller software revisions.
