Running Oracle RAC VMs on vSphere 7

[Robert30]

Hello

I have a question to clarify the type of ESXi Datastore supported to use vmdk files with several Oracle RAC VMs running on vSphere 7 that need to share volumes.

I've been told that multi writer share VMDK disks is only supported with FC SAN

As we are using DELL Compellent, is it supported to configure Oracle RAC VMs using share VMDK disk on ISCSI SAN (Datastore)?

Thanks for your reply

Hi @Robert30 

The process of configuring an Oracle RAC cluster on a vSAN datastore needs to be done once per RAC cluster at creation time. This requires these steps:

• Creating a VM Storage Policy that will be applied to the virtual disks that will be used as the cluster’s shared storage.
• Before vSAN 6.7 Patch 01, creating the shared virtual disks in eager-zeroed mode was needed.Starting VMware vSAN 6.7 Patch 01, shared disks do not need to be eager zero thick (EZT) for multi-writer attribute.
• Attaching the shared disks to one or more VMs
• Enabling multi-writer mode for the VMs and Disks.
• Applying the VM Storage Policy to the shared disks.

I may not have expressed myself badly, but I'm not using VSAN

My question is only about iSCSI SAN Datastore (with DELL storage) and ESXi Servers) supported 

We need to run oracle VMs and would like use for oracle share disk VMDK disk rather RDM disk

We know it's supported with FC Datastore , but is it also supported with iSCSI Datastore

No I didn't get ans answer to know if ISCSI Datastore is supported for this configuration
