Operating instructions

106 Cisco Systems Intelligent Gigabit Ethernet Switch Module
Because the default VLAN for the management VLAN is 1, under the rule above, do not place
blade servers on VLAN 1.
If you change the management VLAN to something other than 1 (by creating a new VLAN,
creating an interface for that new VLAN, and performing a no shutdown on the new interface),
do not
put blade servers on this new VLAN.
The previously mentioned Best Practices document for management and native VLAN
selection has some other great reasons for keeping management traffic and user traffic
separate, but suffice it to say that the requirements of the BladeCenter go even further in
demanding that these networks (the management VLAN and VLANs used by the blade
servers) be kept isolated.
Paths for management of the Cisco Systems IGESM
See 5.3, “In-depth management path discussions” on page 55 for a discussion about the
various paths that can be used to manage the Cisco Systems IGESM in the BladeCenter.
7.3 Base configurations for examples used in this chapter
Before discussing the specifics of the combinations of configurations available in this
environment, it is necessary to discuss some basics of configuration and operation as used
during the creation of this document.
7.3.1 Hardware and software used for the production of this document
The following sections list the hardware and software used during the production of this
document. It should be noted that the choice of the 6500s and their components was made
based on the assumption that the BladeCenter is being deployed in a mission-critical data
center environment, where high availability and high performance are of utmost importance.
IBM eServer BladeCenter configuration
The BladeCenter was configured as follows:
򐂰 Two IBM eServer BladeCenter chassis (8677-1xx)
each with:
– Five HS20s per BladeCenter chassis (8832-21x)
• Two 2.8 Ghz CPUs (#73P5983) upgrades
• One 40 GB Hard Disk Drive (#48P7063)
• Two 256 MB DIMMs and two 1 GB DIMMs (#33L5039) upgrades
• One Gigabit Ethernet Expansion Card (#73P9030) (not used during the creation of
this chapter)
– Four 1800 watt power supplies (#13N0570) upgrades per BladeCenter chassis
– Two Cisco Systems Intelligent Gigabit Ethernet Switch Modules (#13N2281)
– Two BladeCenter Management Modules (#48P7055)
