Cisco Unified Computing System (UCS)-All About

What is Cisco  UCS?



The Cisco Unified Computing System (UCS) is an (x86) architecture data center server platform composed of computing hardware, virtualization support, switching fabric, and management software introduced in 2009.[1] The idea behind the system is to reduce total cost of ownership and improve scalability by integrating the different components into a cohesive platform that can be managed as a single unit. Just-In-Time deployment of resources and 1:N redundancy can be configured with UCS systems



Cisco UCS Platform Emulator, Release 3.0(1cPE1)
The UCS Platform Emulator version 3.0(1cPE1) is a platform release that ONLY supports the 6324 Fabric Interconnect based domains.  No other Fabric Interconnect (6100 / 6200) will work with this UCSPE.

New Hardware Features

Cisco UCS Platform Emulator, Release 3.0(1cPE1), adds support for the following new hardware:

  • Fabric Interconnect IOM: UCS-FI-M-6324
  • Chassis: UCSB-5108-AC2 and UCSB-5108-DC2

Known Limitations

  • Cisco UCS Platform Emulator, Release 3.0(1cPE1) has the following limitations:
  • In the UCSM component topology, the link between the rack server and FI is shown as down.
  • While importing with the ‘Live Import’ feature, adapters other than Lexington do not get imported.
  • Firmware version of components in UCSPE is not visible on the Cisco UCS Central.
  • Disconnecting of the servers by unconfiguring their server ports does not impact the server state.
  • We recommended that you check the imported configuration on the Control Panel to ensure there are no missing components or unsupported components. Unsupported or missing components can impact discovery and it is out of the limitation of the UCSPE catalog that such a scenario can occur. We suggest you delete the unsupported components and add the component manually on the Control Panel. Occasionally, import of rack servers might fail.
  • Live import of the configuration is possible only with the UCS Mini and not with other versions of the Cisco UCS Manager.

NOTE: From UCS PE 2.2(1bPE1) onwards, UCS PE supports uploading the B-Series and C-Series server firmware bundles.  Because of the large file sizes of the firmware bundles, UCS PE only supports uploading of only the stripped-down versions (attached to this document), which includes only the firmware metadata but not the actual firmware itself in the binaries.  The stripped-down version of the firwmare bundles which contain metadata only of the B-series and C-series server firmware is reduced to approximately 50 kB in size.

IV. Title: Installing and Launching Cisco UCS Platform Emulator
The VM performs a one-time installation process the first time it starts up. Allow the installation to complete before you reboot the VM.

Step 1 Extract the Cisco UCS Platform Emulator .zip file and .ova file to a folder.

Step 2 Open or import the unzipped Cisco UCS Platform Emulator into a supported hypervisor, as required by the hypervisor.

Do not continue with the next step until the VM has finished booting.

Step 3 (Optional) If you want to use DHCP for Cisco UCS Platform Emulator, enter the IP address from the VM
console window in a supported Mozilla-based web browser to start Cisco UCS Platform Emulator.

Step 4 (Optional) If you want to assign a static IP address to Cisco UCS Platform Emulator, do the following:

Note Steps 4 f), g), and h) should be repeated three times – one for each of the three interfaces.

a) In the VM console window, at the cisco-ucspe login prompt, enter config and press Enter.

b) At the Password prompt, enter config and press Enter.

c) At the Select prompt, enter a to change the network settings to use a statically assigned IP address.

d) At the Change settings prompt, enter y and press Enter.

e) At the Use DHCP? prompt, enter n and press Enter.

f) At the Enter IP address prompt, enter the static IP address and press Enter.

g) At the Enter netmask prompt, enter your netmask and press Enter.

h) At the Enter default gateway prompt, enter your default gateway and press Enter.

After you enter the default gateway, the network interface reinitializes with your settings.
