Release Bundle Contents for UCS Manager 2.2(2c): Click here
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):
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.
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Outdated configuration backup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.
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
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
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.
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
Hi, we have few UCS N20-C6508 chassis with the N20-PAC5-2500W PSU.I found out in the EOS/EOL notices that the replacement PSU with pid UCSB-PSU-2500ACPL is also EOL/EOS :) The replacement is PSU with pid UCSB-PSU-2500ACDV but...
Hi, with an 8 node HX cluster and LAZ enabled, 4 zones/2 nodes per zone, how many node failures can be tolerated in order to keep the quorum? If the majority of servers must be online than only 3 nodes could fail, right? Or is it different with ...

I have a customer who wants to upgrade to Windows Server 2016, as far as I know SMB v1 is not installed by default in that windows server release, however my customer has their environment running SMB ...
Hello Everybody, What's the difference of software versions between UCSM , FI , DATA Platform , HX?I see that each one has different firmware & sometimes I see they refer to HX version as the same as DATA platform version, is that correct ...
