Consistency Groups and SDRS
Hi all,Our storage is divided in 2+ consistency groups, composed by 5 LUN each one; if 1 LUN fails, all the LUNs grouped in the same consistency group are migrated to the relative failover group.On 1...

Hi Friend, Yes, by default, SDRS will keep your all VMDks from a VM on single datastore. This is what I can confirm at the moment.You can make use of SDRS affinity/anti-affinity rule for placing VM...

yes, I'm using paravirtual controller.I also tried to configure 4 controllers with 4 Vdisks to each controller.

Hi vickyvision2020,I know about the affinity, but our VM will use 2 type of datastores: "FAST" and "SLOW".Fast i used for O.S. Virtual Disk and Slow is used for Data.For this reason we need to load...

>>> Fast i used for O.S. Virtual Disk and Slow is used for Data.Not related to the original question, but IMO the OS usually doesn't produce high I/O, and - without automated storage tiering -...

Giovani, My recommendation is to place the VM in the same consistency group (CG), cause if you place VM in different CG, the VM replicated maybe will be in inconsistent state. VMware will not recognise...

Hi a.p.FAST and SLOW disk is an example to explain our need to use different datastores for a VM.The SDRS should move Virtual disk on the same datastore "type" in the same consistency group. Thank you

Hi Richardson,I follow your recommendation for sure and I'll think also to create a SDRS for single Consistency Group.Thank you for the ideas We actually use EMC Giovanni

Although I guess that the files are orphaned, I'd always double-check for usage before deleting them. Virtual disk (.vmdk) files may not be modified in case active snapshots exist for them. What you...

Although the "mv" command exists in ESXi, you should not use it on VMFS datastores, at least not for large files. What I would do is to:shutdown the VMunregister it from the inventorycopy all the small...
