Here I am going through how to setup LACP port trunking for a Synology NAS device using HP Switching.
1. First off get your MAC Addresses of your Synology NAS interfaces you want to configure, these can be found in the DSM web login under Control Panel > Info Center > Network

VMware have finally released a patch to fix the Major CBT bug that causes your backups to be corrupted because the changed blocks are reported incorrectly.
Within the release notes for the 5.5 latest patch, its kind of hidden away to the point that I missed it the first time.
When you use backup software that uses the Virtual Disk Development Kit (VDDK) API call QueryChangedDiskAreas(), the list of allocated disk sectors returned might be incorrect and incremental backups might appear to be corrupt or missing. A message similar to the following is written to vmware.log: DISKLIB-CTK: Resized change tracking block size from XXX to YYY For more information, see KB 2090639.
You can get the patches below for your version of choice, however there is no fix for ESXi 4.x yet.
ESXi 5.0 Patch 10 – Patch information
ESXi 5.1 Update 3 – Patch Information
ESXi 5.5 Patch 4 – Patch Information
You will need your my.vmware.com login details to access the patch repository to download the zip file, then just import it into your VMware Update Manager within Admin View.

I encountered this issue on a brand new Veeam installation the other day. When running a test backup job.
"Error: NFC storage connection is unavailable, Storage: [stg-datastore-(Number),nfchost-host-(Number),conn:(ServerName)"

So we all know that we should be migrating away from Server 2003 as its end of life June 2015. But until then we still need to manage it.
So lets look at how to extend your hard drives into unpartitioned space using the Dell Extpart tool.
Note: This is probably not supported by VMware, so use at your own risk
So create your unpartitioned space, i.e in VMware, extend the hard drive.
Rescan your disk in Computer Management so the unpartitioned space appears. Right clicking on the drive, you will see there is no extend option, as found in Server 2008 and up.

On twitter Rick Vanover posted this link, which intrigued me, giving your Veeam Server access to the VMware VMFS volumes for quicker backups. Sounds dangerous, or maybe it isn’t!
So I tried it, and I managed to cut my test backup times from 24 minutes to 12 minutes! Also the snapshots are removed from the VMs within seconds.
1. Setup iSCSI initiator on your Windows Veeam server, and get the IQN info. Setup your NIC’s in the correct VLAN for the iSCSI access and with an appropriate IP address.
2. On the storage device, allow access to the necessary volumes from your Veeam server. If possible, set it for read only access! (Here’s me setting up access for a Nimble Device).
3. In the iSCSI initiator dialog box, add in the iSCSI discovery IP, and ensure all your volumes show.
4. ****The Important bit**** Open disk part and enter the following “automount disable”
5. Open up computer management and you should see that you now have disks showing from the Storage Array, for me, I had to click these to “Online” otherwise Direct SAN access wouldn’t work.
6. Within Veeam I then changed my Backup Proxy settings to only use “Direct SAN” mode so that I could test it and ensure it was working.
7. Run a backup and enjoy faster results, here’s my before and after shots (the second run I ran “Active Full” as the job is set to do reversed incremental).
