Quick Tip - Verifying vCenter Server Appliance (VCSA) Backup Status

by // 13 Comments

I recently found out that my vCenter Server Appliance (VCSA) scheduled backups had been failing for some time but I was not aware. While there is a default vCenter Server alarm for failed VCSA backups, however it is only visible when you have selected the vCenter Server inventory object in left hand navigation, which is not a typical item that I select as shown in the screenshot below.


Furthermore, I was actually logged into the VCSA's VMware Appliance Management Interface (VAMI) not too long ago while updating to a newer patch release and I had checked to see if backups were successful, which I thought they were when looking at the "Status" column.


It was not until I took a closer look, did I realize that the schedule backup activity log is ordered from oldest to newest, meaning what I saw was a backup that has happend a long time ago and not necessary the latest backup attempt. I found this to be a really strange UX since as you would need to page to very end to check whether the latest backups were succssful or not.

Note: I have already filed an internal bug to ask for the VCSA schedule backup activity to be ordered from newest to oldest, so users can quickly see if the latest backups are successful or not.

Experimenting with ESXi CPU affinity and Intel Hybrid CPU Cores

by // 21 Comments

After debugging a recent issue with using VMware Workstation and Intel Hybrid CPUs, it gave me an idea about an experiment to try with ESXi and Intel Hybrid CPUs.

As a refresher, starting with the Intel 12th Generation (Alder Lake) CPU, a new hybrid big.LITTLE CPU architecture was introduced for consumer Intel CPUs. This new hybrid Intel CPU architecture integrates two types of CPU cores: Performance-cores (P-cores) and Efficiency-cores (E-cores) into the same physical CPU die. For more information about this new hybrid Intel CPU design, check out this resource HERE. The ESXi scheduler does not and has no current plans to support this new Intel Hybrid CPU architecture, especially as this type of architecture is nowhere to be found in traditional Enterprise datacenters and is only limited to Intel Consumer CPUs.

The current recommendation to work around the non-uniformity of the CPU cores is to either disable the E or P-cores within the system BIOS, thus making the system "uniform" and allowing ESXi to run like a normal x86 system. While you can apply a workaround to have ESXi ignore the non-uniformity of the CPU cores, in addition to the non-deterministic behaviors, random PSOD can also occur due to scheduling across two different types of cores.

I was curious to see whether applying ESXi CPU affinity on a VM using Intel Hybrid CPU Cores might yield a different outcome?

What's in the new VMware vSphere Foundation (VVF) and VMware Cloud Foundation (VCF) offers?

by // 151 Comments

Since the announcement of the two new VMware offerings: VMware vSphere Foundation (VVF) and VMware Cloud Foundation (VCF) at the end of 2023, I have been trying to wrap my head around the new offers and to better help me understand the next level of details, I have put together several diagrams across the various offers and applicable add-ons that can be purchased.

After sharing these diagrams internally, the feedback was extremely positive and I thought I would also share these diagrams with our users and partners who might still have questions around the new offers. I have also created a short URL which you can access by going to vmwa.re/skus

In addition, we have also published a VMware KB 95927 (Inventory Script) and VMware KB 96426 (Calculator Script) that can be used to help our users understand the new licensing model which uses both CPU cores and TiB (for vSAN storage sizing), please refer to the KB articles for more details.

Changelog:

  • 11/08/24 - Updated with new SKU offers (vSphere Enterprise Plus & VCF Edge)
  • 03/20/24 - Updated with VMware Live Recovery (VLR includes LSR & LCR) and Private AI Foundation Add-On
  • 02/16/24 - Updated VCF w/CSP + new VMware by Broadcom theme colors
  • 02/13/24 - Removed 8TiB minimal purchase per new VMware KBs & updated VCF w/VMware Data Services Manager (DSM)
  • 01/12/24 - Updated VCF w/TAM, PSO and Learning Service Add-On
  • 01/09/24 - Updated VCF w/CSP Add-On and VCDR/RWR/SRM Add-On for VVS/VVEP
