HA with Backups ?

Friends,

In an HA environment, you guys find it necessary to back up virtual machines?

Let me explain.

I have two clients that have connected VMware servers in storage, a MD3000 andMD3000i with another client in three years that never stopped because of VMStorage, these VMs are Storages. These devices have 4 NICs / HBA, two controllers, hot-spare disks, two sources are reliable, we see a Storage hardlypresent a problem to send into space all the VMs.

The thing is I did a project is no alternative, using Veeam Backup & Replication, twoESXi hosts, each host with an Iomega NAS Storage to store VMS, Veeam replicatefrom one host to another, putting the machines in Storages.

Only the client for reasons of standardization all Dell prefers to use, it has a host DellPE 1950 with 8GB RAM, will put more memory reaching 24GB, this server has twoIntel Quad-Core 5500 series. Then it will be bought a new Dell PE R410 server with 32GB RAM and two Intel Quad-Core and a Dell PowerVault Storage 3200i, thisstorage will be VMs, hosts HA using the vSphere Essential Kit Plus.

So how the project is already relatively expensive, discarding the design permits the purchase of Veeam Backup & Replication and Storage Iomega an extra store thesebackups, as you can see the customer will have advanced equipment, and Storageof a smart, robust, has a 1% chance of having an accident problem that commits allVMs.

What do you think?

Another thing, is there any restriction on making a HA servers using different models, although of the same manufacturer? Any restrictions with processor for example? In another project I did and even posted in the community, uses twoidentical Dell R410.


Thanks guys, now is to redesign the project here, using Veeam remove HA HA and use with vSphere Essentials Plus Kit.
