Hi Boris,

The best practice would be not to use bus sharing, as snapshots are not supported for these kind of disks. Usually people use SQL Server AlwaysOn instead of clustering it via Failover Cluster feature. Please review this topic for more info.

Thanks!

I was testing Server 2016 Storage Replica to possibly replaced some old DFSR, but unfortunately that also has to use bus sharing so my plans have been scuppered :(

Hi Vitaliy,

thanks for your reply, but unfortunately AlwaysOn is not the same as a "real" FCI, in my opinion AlwaysOn is like a narrow gauge cluster without the need for shared storage.

An FCI covers everything about the SQL instance - databases, logins, certificates, policies, agent jobs, and more. Whether you have two databases or hundred databases, they will all go together. An AvailabilityGroup will only fail over the data in the databases that are in the group. You must separately manage everything else. The more replicas you add, the more complex management becomes.

maybe this is one reason I'm considering to move away from VMware to Hyper-V because there are snapshot capable shared VHDX available

Ok, thanks for clarification, makes sense. If you're considering VHDX, then please take a look at this topic > Backing up a Windows Failover Cluster with Shared vhdx?

[MERGED] File server MS Failover Cluster, Storage Snapshot,

Veeam Logoby jguillot » Wed Dec 13, 2017 7:38 am

Hello,

I would like to use Microsoft Failover Cluster with 2 Windows Server 2016 servers to make high availability file servers with shared volume for data.

Here is my architecture:

Main site:
  • 4 ESXi in connection (iSCSI) with HPE StoreVirtual VSA for storage (SDS).

Emergency site (DR):
  • 2 ESXi in connection (iSCSI) with a big NAS.

Backup infrastructure:
  • Veeam Backup & Replication
  • HPE StoreOnce VSA
  • Main backup on a DAS Bay
  • Backup copy on a remote NAS

My goal :
  • The 2 file servers would be on ESXi different from the main site.
  • Shared storage of file servers would be on a volume of the HPE StoreVirtual VSA.
  • Backup the VMs on the DAS array (through Veeam B&R and StoreOnce VSA) using StoreVirtual VSA Storage Snapshots.
  • And also to continually replicate all my VMs to my DR site.

1) Is it possible?
2) Shared storage of file servers can be a VMDK? At first I thought I would use vRDM but apparently Veeam does not support Storage Snapshot on them. No worries with vMotion?
3) How is the backup of the 2 file servers with a shared VMDK? the VMDK is saved 2 times?
4) How is replication done with a shared VMDK?

thank you in advance

Ps : Sorry for my poor english

Veeam B&R itself doesn't support VM's with shared storage, so I'd look at Veeam B&R 9.5 Update 3 that adds Windows Failover Cluster support for Veeam Agent for Windows.

I read the release notes of Update 3. Does this mean, that all the limitations from KB2304 https://www.veeam.com/kb2304 are gone?
Or is there a detailed documentation about what is supported?

Hi Simon,

Not all limitations are gone. Please review this and this topic in the Agent forums. Thanks!
