WIN8.1 acting as Server - No Hot Add

[TParticke]

Hello,

[Case # 00591706]
I know that we talked about a similar problem (Windows 7 acting as B&R Server and Proxy) and I know that Windows 8.1 should be fully supported,
but in our case it seems not to.

Environment:
Branch Office (30 Locations, Germany)
VMWARE ESX 5.5 U1 R2 latest Patches
5 VMs. Server 2003, 2008, 2012R2, WIN7, WIN8.1 [B&R | Proxy | WAN Acc | 10GB | 4 Cores | Attached QNAP iSCSi Datastore as Local Datastore for VEEAM]

Central
2 VMWARE ESX 5.5 U1 R2 [Cluster] latest Patches
DL 380 G8 | Windows Server 2012 R2 | B&R | Proxy | WAN Acc | 64GB | 4 Cores | Local SSD RAID 5 for Caching | Attached HP P2000 G3 60TB SAS)


In our Test Environment we used a Windows Server 2012 R2 without any Problems, but now we want to use a Client OS (license costs).

What we want to do is having Windows 8.1 as B&R Server | Proxy | WAN Acc in our Branch Offices.
Everything works fine except the HotAdd Feature, what means the B&R Server falls back to Network Mode (Remember, you get only
40% Performance from VMWare IP Stack..)
In real it is ~ 40-50MB/s, not really bad, but nothing against the ~190MB/s with HotAdd.

What we checked so far:
read the KB Article
http://www.veeam.com/kb1054 http://forums.veeam.com/vmware-vsphere- ... -this-disk....
We have No iSCSi Problem (Only 1 LUN | 1Gbit)
No different VMFS Datastores (3/5) Hardware of all Machines to backup is V8 NO IDE drives.
VM Ware Tools are Up to Date.
Veeam 7.0 Patch 4 is installed.
Proxy is in same subnet (same Machine) License from VEEAM and ESX is correct.
Restarts of ESX Hosts and Backup Server is done (Multiple times).
Manually attaching a VM Ware Snapshot to the Proxy works.
---------------------------------------------------------------------------------------------------

short:
Windows 7 works fine! Windows Server 2012 R2 works fine! But Windows 8.1 [HotAdd] does not.

Is anyone here, having the same problem or having a good idea?

Your help is highly appreciated.

Are you able to manually hot add the disks to the VM in question, using vSphere client? Thanks.

Hi Thomas,

Is this the only Windows 8.1 server you have to try as a proxy server? Also just to make sure we're on the same page - you're referring to proxy servers used at source site to retrieve VM data and you're using backup jobs, not replication?

Thanks!
