2024年4月13日 · The Cisco UCS 2408 IOM is an I/O module (fabric extender) with 8 25-Gigabit SFP28 uplink ports to the fabric interconnect and 32 10-Gigabit backplane ports to support up to 8 half-width blade servers in the chassis.

2024年4月13日 · The chassis houses two I/O modules (IOMs) that allow the blade servers in the chassis to communicate with Cisco UCS fabric interconnects. In the Cisco UCS Mini Server Chassis, the same slot that is used for an IOM is used for the Cisco UCS 6324 Fabric Interconnect. Up to two of these modules can be installed in the chassis.

2011年7月15日 · The basic concept is simple (in most cases) – for each port you need on a given blade server, you need to have a corresponding I/O module. For example, if you need 4 NICs, you’re going to need 4 Ethernet modules (in most cases.) In today’s post, I thought I would keep it simple and publish the I/O diagrams of Cisco, Dell, HP and IBM chassis.

In Cisco UCS, all network traffic flows over FCoE directly from the chassis backplane to an FI (Fabric Interconnect) device. To make sure that the blades in the chassis receive prompt and uninterrupted networking services, you need to frequently check whether the backplane ports of the chassis are available and operational.

With the help of these tests, you can keep an eye on the status of each chassis managed by the Cisco UCS manager and also its core components such as the fabric extemders, fan modules, power supplies, etc., and quickly detect abnormalities. The following topics discuss the tests associated with this layer in detail:

2015年3月4日 · Since Cisco started shipping UCS in 2009, the Cisco 5108 chassis uses the same backplane. It is designed to connect 8 blades and 2 IO Modules. The backplane contains 64 10Gb-KR lanes, 32 from IOM-A and 32 from IOM-B. All UCS Chassis sold to date have this backplane which provides a total of 8 10Gb-KR lanes going to each blade slot.

2018年5月1日 · Both IOM are active if you have vNIC pinned to both A and B side fabrics. You want connections from FI-A to IOM-A and FI-B to IOM-B. You have 20G on A side and 20G on B side, however, if you have eight blades in a chassis, this 20G is divided amongst the blades.
