The UCS Manager 2.2(2) release enables support for new Intel Ivy Bridge server platforms, and delivers key features and enhancements in the Fabric and Operational areas. The following is a complete overview of the new hardware platforms and software enhancements in UCS Manager 2.2(2):

 

Hardware Support:

  • B260-M4 & B460-M4 (Scalable 2S-EX & 4S-EX blade servers)
  • B420-M3 (4S-EP Ivy Bridge blade server refresh)
  • B22-M3 (2S-EN Ivy Bridge blade server refresh)
  • C460-M4 (4S-EX rack server)
  • C22-M3 & C24-M3 (2S-EN Ivy Bridge rack server refreshes)
  • High Voltage PSU (380v) Support

 

Note: New SAP HANA solutions are based on the M4 server platforms, B260-M4, B460-M4 and C460-M4.

 

 

Operational Enhancements:

  • Scriptable vMedia
    • Scriptable vMedia provides the ability to programmatically mount an image on a remote server directly to CIMC (without requiring KVM).
    • A new vMedia Policy allows the user to define the vMedia mapping and specify the remote NFS/CIFS/HTTP/HTTPS share. The vMedia mount can be referenced as the boot device in the Boot Policy.
    • Scriptable vMedia enables key use cases such as scripting OS driver updates, security updates, and “PXE-less” automated OS provisioning.

 

  • Pre-Upgrade Validation Checks
    • Provide pre-upgrade checks to enhance the firmware auto-install process and ensure a smooth and successful upgrade process
    • Prior to an upgrade, the complete UCSM domain will be audited and warnings will be shown based on the configuration state, in case of:
      • Outdated configuration backup
      • Any critical/major faults exist
      • Management interface monitoring policy is disabled
      • FI reboot is pending
      • NTP configuration is not available

Also, an error will be shown in case the available Bootflash space is less than 20%

    • A new “Backup Config Reminder” option is added to the Backup Policy

 

  • GPU Firmware Management
    • UCSM Firmware bundles now contain GPU firmware
    • UCSM Host Firmware Policies can now designate desired firmware versions for supported Nvidia GPU Adapters

 

  • Wear-Level Monitoring for Flash Adapters
    • UCSM Monitoring for the Flash status and remaining Flash Life of Fusion IO Flash Adapters

 

  • KVM/vMedia Client Enhancements
    • Support the next gen KVM/vMedia client on UCS servers for better server management experience
    • vMedia tab replaced with a menu option, allowing continuous access to the KVM console while creating a vMedia mapping, as well as caching of previous vMedia mappings for faster remapping.
    • Other enhancements include a Chat option across multiple users of KVM sessions, Video Scaling allowing the KVM window to be resized according to the client resolution, and Auto-Reconnect allowing the client to automatically re-establish the session in case of connectivity loss.

 

 

Fabric Enhancements:

  • PVLAN Enhancements
    • Enhances the current implementation of PVLAN extending support to Community VLANs, Promiscuous mode, and PVLAN trunking on the host side
    • Support both physical and virtual environment, enhancing the support and interoperability with ESXi and N1Kv

 

  • Netflow Support
    • Enable high scale flow record collection with minimal overheard on the FI by distributing the NetFlow processing to the Cisco VIC adapters on the servers
    • Enhances the visibility required to detect traffic anomalies, ensure efficient bandwidth allocation and improve capacity planning
    • UCS Manager will create and manage Netflow policies, which can be applied to static and dynamic vNICs (VM-FEX) to capture VM to VM traffic within the same host

 

  • Cisco VIC Driver Enhancements – Adaptive Interrupt Coalescing (AIC)
    • Enables self tuning of the CPU interrupt for packet processing, by interrupting the host only once for multiple packets received, based on a defined coalescing timer
    • Improves the CPU efficiency and throughput, reducing the number of kernel context switches required to service the interrupts generated by the adapter
    • AIC relies on the eNIC driver to learn the nature of the traffic flowing through it and tune the interrupt coalescing timer to improve the CPU utilization without negatively impacting the traffic latency.

 

  • Cisco VIC Driver Enhancements – Accelerated Receive Flow Steering (ARFS)
    • ARFS is a hardware-assisted receive flow steering, with the goal of increasing data cache hit rate by steering kernel processing of packets to the CPU where the application thread consuming the packet is running
    • ARFS helps improve CPU efficiency and reduce traffic latency
    • ARFS is disabled by default and can be enabled from the Adapter Policy in UCSM

 

  • Cisco VIC Driver Enhancements – NetQueue Support
    • Enables support for VMware NetQueue on the Cisco VIC adapter
    • Allows a network adapter to dedicate a transmit and receive queue pair to a virtual machine NIC
    • Improves network throughput by distributing processing of network traffic for multiple VMs among multiple CPUs
    • Reduces CPU utilization by offloading receive packet filtering to the network adapter
