Chapter 31. BladeCenter
®
JS20
Notes:
1.
2-way blade server installs in a BladeCenter chassis. KVM support is not provided; use serial over LAN
communication to perform local, network operating system or software installation as an alternative to
KVM. Up to 14 JS20 blade servers are supported in the BladeCenter chassis and up to 8 JS20 blade servers
are supported in the BladeCenter T chassis. Power modules in BladeCenter models 1XX will need to be
upgraded to 1800w power modules in order to support JS20 blade servers.
2. PowerPC 970 processors with full-speed L2 cache. All models have a 1.1GHz Front-side Bus (FSB).
3. Memory is two-way interleaved, PC2700 ECC DDR RDIMMs.
4. System management functionality, interconnect network connectivity and console connectivity are
managed through the standard management module. The standard integrated service processor
monitors JS20 system management activity, communicating with the management module in the
BladeCenter.
5. Broadcom dual-port integrated copper gigabit Ethernet controller.
6. Maximum HDD storage capacity is based on installation of two 60GB 5400rpm ATA-100 HDDs.
7. Installation of an I/O expansion card prevents installation of a 2nd IDE HDD.
8. NEBS compliant.
9. Maximum memory capacity is based on installation of four 2GB PC2700 ECC DDR DIMMs.
