Disks

Disks

  • Dell EMC vSAN Ready Nodes support up to 24 disks per node. For the two-socket R740xd vSAN Ready Node and the four-socket R840 vSAN Ready Node, only all-flash configurations are supported for SAP HANA. NVMe disks are required for the caching layer. Configurations are supported with a minimum of two vSAN disk groups per node and a minimum of three capacity disks per disk group.

    Based on capacity requirements, you can configure up to four disk groups with a maximum of five capacity disks per disk group.  Every vSAN Ready Node must have the same disk group configuration—that is, balanced disk groups. As a best practice, the number of disk groups in the vSAN cluster must match the number of production SAP HANA VMs running in the cluster.

    Assign the RAID 1 failure tolerance method in the storage policy to the SAP HANA persistence (data and log of each SAP HANA VM), as described in Assign VM storage policies to the SAP HANA persistence. This means that twice the capacity of the data and log devices is required as SSD/NVMe capacity.

    Although RAID 1 is the default storage policy for all VMs on vSAN and is specifically required for the persistence of production SAP HANA devices, you can create a new capacity-optimized storage policy with RAID 5/6 and assign it to other non SAP HANA persistent devices. RAID 5/6 consumes 1.33 times the usable device capacity on disk.
