drives or the SSD disk units can be RAIDed however, the drives must be of the
same type. It is also preferred to have drives of the same capacity but, RAID can
be performed using dissimilar capacities. If differing capacities are used you will
only have the effective capacity of the smaller drive.
2.6 IBM BladeCenter chassis
The BladeCenter JS23 and BladeCenter JS43 Express blade are supported in
the BladeCenter chassis as shown in Table 2-20. Note that operating system
selection (in particular IBM i) should be taken into account for overall system
support.
Table 2-20 BladeCenter JS23 and JS43 chassis support
Three chassis are available in the BladeCenter chassis family:
IBM BladeCenter H delivers high performance, extreme reliability, and
ultimate flexibility for the most demanding IT environments.
IIBM BladeCenter S combines the power of blade servers with integrated
storage, all in an easy-to-use package designed specifically for the office and
distributed enterprise environment.
IBM BladeCenter HT models are designed for high-performance flexible
telecommunication environments by supporting high-speed inter-networking
technologies such as 10 Gb Ethernet.
Table 2-21 provides a list of supported BladeCenter chassis and the total number
of JSXX blades installable into a chassis. This table describes the physical
limitations of blades in chassis.
Blade BC H BC S BC HT BC T BC E
JS23 YES YES YES NO NO
JS43 YES YES YES NO NO
Note: There are limitations to the number of blade servers that can be
installed into the chassis. It is dependent on the power supply configuration,
power supply input (110/220V) and power reduction/redundancy options. See
“Number of IBM BladeCenter JS23 and JS43 Express in Supported Blade
Center Chassis” on page 37 for more information.
