Cisco has released the 3.0(2) beta version of the the Cisco UCS Manager VMware vSphere HTML client plugin. These version is working with vSphere 6.7. It’s currently running and enabled on 9 different clusters – 290 hosts. It works great so far.
Here are the new and changed features in Release3.0(2):
- Included defect fixes
- Added a new fault (F1706)to the Cisco UCS Provider failure conditions list
- Added support for proactive High Availability for more than 100 hosts in vCenter
It is great to combine it with new Cisco UCS 4.1.1 because of Intel Post Package Repair (PPR).
- Intel Post Package Repair (PPR) uses additional spare capacity within the DDR4 DRAM to remap and replace faulty cell areas detected during system boot time. Remapping is permanent and persists through power-down and reboot.
- Newer memories, such as double data ram version 4 (DDR4) include so-called post-package repair (PPR) capabilities. PPR capabilities enable a compatible memory controller to remap accesses from a faulty row of a memory module to a spare row of the memory module that is not faulty.
- Hard-PPR permanently remaps accesses from a designated faulty row to a designated spare row. A Hard-PPR row remapping survives power cycles.
- Soft-PPR remapping temporarily maps accesses from a faulty row to a designated spare row. A Soft-PPR row remapping will survive a “warm” reboot,but does not survive a powercycle.
- You can enabled it in BIOS policy / Memory RAS configuration – Select PPR type configuration – Hard PPR
- To support “Alert F1706 – ADDDC Memory RAS Problem” is necessary
ADDDC Sparing—System reliability is optimized by holding memory in reserve so that it can be used in case other DIMMs fail. This mode provides some memory redundancy, but does not provide as much redundancy as mirroring.
- Cisco recommends upgrading to 4.0(4c) or later to expand memory fault coverage. Beginning with 4.0(4c) an additional RAS feature, Adaptive Double Device Data Correction (ADDDC Sparing) is available. It will be enabled and configured as “Platform Default” for Memory RAS configuration.
