VMware ESXi – Get VM’s by VLAN ID with PowerCLI

Often when when working in large environments you’ll get interesting requests. These may be to assist in troubleshooting, auditing, reporting or any other reason. I was recently requested to provide a list of mac addresses for every VM with a vNIC in a specific vlan. I had a feeling this was going to be a repeated request (for various vlans) so presented… Read more »

The DELL PowerVault MD series Storage Arrays are solid and reliable units. Whilst I don’t use any for what may be considered “Primary” Storage, I use them for many workloads.

CommVault – The need for speed, pt 1

EMC XtremIO 4.x – AD LDAP Configuration

Configuring Active Directory (or really LDAP) based authentication for your infrastructure is basically standard fare. Default accounts should always be changed and centralized management and control of access credentials saves you effort over time, and is “Security 101” With that in mind I set about configuring LDAP authentication against an Active Directory on a freshly minted XtremIO 4 cluster, so thought… Read more »

EMC RecoverPoint : Automated Protection Window Summary

One thing that is often overlooked after a RecoverPoint solution is implemented is the ongoing Protection Window value for your Consistency Groups.  During the design phase, the Journal sizes are (hopefully) diligently and accurately calculated according to your RPO.
