SRM, a real world example July 1, 2012

One of the things that we as instructors get marked on is Real World Examples.

As you may have read or seen on the TV, Newcastle upon Tyne got hit by some rather nasty weather.

So this little post talks of the real world value of the VMware Site Recovery Manager product.

My friend, also called Brian, has his own company; he has a lot of home workers and also some office staff. On Thursday night the rain came down, and unfortunately Brian’s office was at risk of getting flooded, Brian rang his IT support company and the response was leave it to us we’ll ring you back in 15 minutes, there’ll be a little bit of down time, but we’ll keep it to a minimum.

He then got a phone call back within 5 minutes, and got asked to go to his server room and power down the servers. Brian obviously was a bit concerned about this, but he didn’t want the servers to burst into flame, electricity and water don’t really mix, so the servers got turned off. The strange thing that Brian found though was that the systems were still working.

What had happened was; Brian’s support company use VMware Site Recovery Manager, the IT support company had performed a Planned Migration to their data center.

Brian sent his employees home and told them that for Friday everyone work from home.

Good news, unlike my mum (see previous post from myself) the office steps had got a bit wet, but water hadn’t entered the building, the IT support company arrived, powered back up the servers and on Saturday migrated the systems back. On Monday everything will be back to normal.

So the point of the story, with data centers being able to be located anywhere, and with data being able to be located anywhere, with virtualisation technologies we can replicate data and protect against disasters

On the course this week we’ve talked about various HA scenarios that we need to protect against, one of the topics refers to protection at every level within the vSphere product.

Here goes.

At the component level we have NIC Teaming on our virtual switches and that will protect against a NIC failure, we also have storage multipathing.

At the Server level we have vMotion, Distributed Resource Scheduling, High Availability and VM Fault Tolerance.

At the Storage level we have Storage vMotion and Storage DRS.

The Data level is protected by the vStorage APIs which allow third party backup solutions such as Veeam, or we can use VMware’s Data Recovery Virtual APP.

Now onto the Site Level, I’ve been looking at SRM V5, I’ve used the various different versions of this product, but now I’m concentrating on Version 5 and for me, it’s much improved.

To summarise the product, SRM is designed to protect Virtual Machines residing in datastores on replicated storage at the protected site. In the event of a storage failure or a complete site failure, the Virtual Machines can be failed over to a remote datacentre or if you prefer the recovery site. The recovery virtual machines continue to operate while the protected site is unavailable.

So why am I mentioning all of this, the reason is I work for a VMware Authorised Training Center, we run SRM courses.
