When we get root access (how is explained later in this post), from /proc/version and the install log, we determine the OS is a cut-down version of CentOS 4.4.3 (see tiny-centos.sh below) running on Linux kernel v2.6.9 with SELinux disabled.
What is displayed above is the classic Red Hat SysVinit scripts output. The only changes I have made to the downloaded OVA is to change the network settings for the three interfaces shown from NAT to host-only and remove the floppy drive.Īfter starting the VM, you can see UCSPE is running on some sort of a Red Hat or downstream derivative: It is assumed that you are familiar with UCS if you are reading this post and therefore no attempt is made to explain, UCS, UCSM, service profiles, the underlying UCS architecture or UCS managed objects.įirst of all, here are my VMware Workstation virtual machine settings. This post looks under the hood at the internals of the UCSPE and documents a number of interesting things. Amongst other uses, it enables users to become familiar with the UCSM GUI, troubleshoot UCS configuration problems, and provides a convenient way to demonstrate UCS operations for training purposes. The UCS Platform Emulator (UCSPE) was developed by Cisco to enable the use of Cisco UCS Manager and the UCS XML API without requiring actual physical hardware. A DME uses a number of Application Gateways (AG) to talk to the managed physical aspects of the system–server baseboard ( CIMC – Cisco Integrated Management Controller), supported LAN and SAN devices (CNAs and HBAs), fabric subsystems (IOM/FEX), and the FI itself.
The core of UCSM is the Data Management Engine (DME) which is persisted in an XML database. A FI is essentially a Top-Of-Rack switch as far as UCS is concerned.

One of the key advantages of UCS from a system administration perspective is the radical reduction in system management points to a single management point called the UCS Manager (UCSM) which is implemented as an NX-OS kernel module in a Cisco Nexus 6000 series Fabric Interconnect (FI) switch. It was originally developed as a data center server technology optimized for VMware virtualization workloads, but nowadays is used in many mid-size and large enterprises. Cisco UCS (Unified Computing System, codenamed Project California during development) was introduced in 2009.
