Now that our new PS6000 is initialized and ready to go, we started to look at replication and what we wanted to achieve in terms of backup/recovery and failover/failback. The idea was to replicate our Hyper-V virtual Machines to this second PS Series group and also all our users data. The Second PS Series group will be onsite but at the furthest most point away from our primary PS Series group in a seperate building. We also needed to look at our SAN Network topology and how we needed to extend this to give us the High Availability and bandwidth we required.
EqualLogic comes with SAN based replication built into the inclusive licensing model and with tools such as SANHQ and Dell's Manual Transfer Utility or MTU for short configuring replication is once again a nice and easy process.
Firsty lets take a quick look at what EqualLogic replication is and what it involves.

With Microsoft now being considered a virtualisation leader (Gartner 2011) isn’t it time you considered switching to Hyper-V and saving your organisation money? Carmel College have done just that, and will discuss the rationale behind their migration from VSphere and the benefits they have realised. We will explore the Microsoft Hyper-V Private Cloud Solution and you will be able to get answers to all your burning questions.
If you have been keeping upto date with my previous blog articles, you will know that we have recently taken delivery of a Dell EqualLogic PS6000 32TB. My intention is to use this as a replication partner for our existing PS Series Group.
With the new EqualLogic initialized and firmware upto date, I continued to set up replication, this was again as expected with EqualLogic a quick and painless task, I will blog on setting up replication in another article.
For the initial replication we co-located our new EqualLogic in the same Datacentre as our current PS group, created replication schedules and away it went all volumes replicated and continuing to replicate on an hourly schedule, no issues what so ever. All of this on our backend iSCSI network of course.
The next task was to move our replication partner to our secondary Datacentre accross the other side of our site in a seperate building, to offer onsite replication. the link to this secondary Datacentre is a 6GB MLT using Nortel/AVAYA as now is, Ethernet Routing Switch 5500 Series. We needed a way of transporting this backened iSCSI traffic over our current network infrastructure.
