Chapter 5. IBM BladeCenter HX5 205
Table 5-23 Supported SSDs
For more information about SSD drives and their advantages, see 2.8.1, “IBM eXFlash
price-performance” on page 49.
5.11.2 LSI configuration utility
Figure 5-20 shows the LSI SAS Configuration Utility window running on a 2-node HX5 with
one controller in each node. The SAS1064 that is listed first is always the primary node
controller and the SAS1064 that is listed second is the secondary node’s controller.
Figure 5-20 LSI Configuration Utility
In a 2-node configuration, each controller operates independently, and each controller
maintains its own configuration for the sets of drives that are installed in that node. One
controller cannot cross over to the other node to perform a more complex RAID solution.
Using independent controllers allows for several configuration options. Each LSI 1064
controller has an option of RAID-1, RAID-0, or JBOD (just a bunch of disks). No redundancy
exists in a JBOD configuration, and each drive runs independently. The blade uses JBOD, by
default, if no RAID array is configured.
Figure 5-21 on page 206 shows the three options in the LSI 1064 setup page, LSI Logic MPT
Setup Utility. Only two options are supported with this blade, because there are only two
drives maximum that are installable in the HX5 and an Integrated Mirroring Enhanced (IME)
volume requires three drives minimum.
