Document Purpose: Quick reference for BladeCenter Interoperability. Compliment to ServerProven, COG, and the Configuration tools with ServerProven being the most reliable, accurate, and up to date tool.

This paper is intended to provide information regarding BladeCenter Interoperability. It assembles data from other published IBM tools. Findings may not be realized in all customer environments, and implementation in such environments may require additional steps, configurations, and performance analysis. The information herein is provided “AS IS”“ with no warranties, express or implied. This information does not constitute a specification or form part of the warranty for any IBM, Brocade, Cisco, Emulex, McData, Myrinet, NetXen, Nortel, or QLogic products.

compatibility

Compatibility for BladeCenter products The IBM ServerProven® program validates selected products for compatibility with IBM System x™, BladeCenter® and xSeries® servers. Through the ServerProven Program, IBM works with industry leaders to test their equipment with ours. We recognize that you deserve the most innovative solutions...even if they're not all from IBM. IBM ServerProven provides compatibility information only. Hardware configuration guidance can be obtained from the Configuration and Options Guide. Product ordering information can be obtained from the Sales Configurators. These configurators can be accessed through the link "Configuration Tools" which is located on the left side of this page.

Notes:

Y = no restrictions on the number of blades, all blade slots may be used W = CPU power in watts Note-1 Non NEBS environment (see table at end of documents for NEBS statements)

Note-2 If fully configured, must leave 1 slot open in power domain 1

Note-3 When fully configuring a BC-E (8677) chassis with the maximum possible HS21 XM blade server

configuration (fourteen HS21 XM blade servers, each with two 80W processors, eight 4GB memory DIMMs,

one SAS HDD, one USB-based flash drive, one I/O card and one cKVM card), there could be periods of time

that Power Domain 2 exceeds the 13.5amp rating guidance (Power Domain 1 will not exceed the rating

guidance). While this is not violating any safety rules, we recommend that your clients review the electrical

infrastructure and power distribution of their installations to account for a peak of 14.4A

Note-4 95W is supported but will throttle performance to fit in power envelope – recommend using in BladeCenter H or HT. This is true for processor models 22xx and 82xx. They will run n-2 speed in BladeCenter E and BladeCenter T chassis. However, processor models 23xx and 83xx do not have the ability to run n-2. They are not supported in BCE or BCT. Note-5 HC10 (7996) requires AMM on E chassis.

Note-6 When the JS21 blade boots, the BMC will determine what chassis it is running in and "set" accordingly the processor frequency. The 2-way configuration functions at 2.7GHz processor frequency in BladeCenter H (8852) or 2.6GHz processor frequency in all other BladeCenter chassis. The 4-way configuration functions at 2.5GHz processor frequency in BladeCenter H (8852) or 2.3GHz processor frequency in all other BladeCenter chassis. Note-7 Supported only in Non-NEBS environment

I/O Modules to Chassis Interoperability continued A Brocade SAN Switch Module for BladeCenter or any other Brocade switch or director utilizing the Fabric OS Access Gateway mode can connect to an INCITS T11 NPIV compliant device. The Brocade Access Gateway mode was designed to adhere to this standard. In addition, any INCITS T11 NPIV compliant device can connect to a Brocade switch or director that supports NPIV connectivity. Brocade does not test or make a discreet statement of support for any other vendor’s devices. Brocade will assist IBM with problem determination for compliant configurations.
