vSAN insufficient memory (2071753)

  • 0 Ratings



System memory is insufficient for the number of  vSAN disks.


Depending on the system RAM, vSAN limits the number of disks that can be configured for vSAN on the system. On systems with more than 32GB RAM, up to 5 solid state disks (SSD) with up to 7 spinning disks per SSD are permissible. On systems with less than 32 GB RAM, the following formula might be used:

max-spinning-disks = MAX((RAMinGB - 4) * 35 / 28, 1)
max-SSDs = MIN(max-spinning-disks, 5)


vSAN cannot use all disks attached to the system.


If the system RAM is less than 32 GB, increase the system RAM. If it is greater than 32 GB, keep the number of vSAN disks less than 35.
