  • 1.  Is DB2 PureScale compatible with StarWinds Vsan?

    Posted 03/05/24 09:54 PM

    I am curious about running DB2 PureScale with a two node StarWinds Vsan setup. Is this supported/tested? Or is a true SAN needed given the latency required by PureScale?

    To check supported shared storage for Db2 pureScale, please check:

    https://www.ibm.com/docs/en/db2/11.5?topic=linux-shared-storage-support

    All storage devices and multipath I/O driver combinations not identified as category 1 or category 2 fall into category 3. Category 3 combinations have not been validated with the Db2 pureScale Feature, though they are supported.

    Are you going to use Virtual machines as CF and/or data members?

    For VMs only certain hypervisors are supported, moreover shared storage in virtual machine is supported providing that you can assign storage Fibre Channel (FC) adapters to the guest virtual machines by using the PCI device pass-through mode. After you assign storage adapters, you can directly access storage area network (SAN) disks from inside the guest VM. Tie-breaker disks and SCSI-3 PR I/O fencing are supported in this environment.

    So it looks like my original plan of a NetApp/Lenovo San is my best option. No, I wont be using a VM. From what I understand, DB2 community edition can use more resources when NOT in a vm. The licence allows 2 physical cores per node (4 total) when ran on the host os.
