Going to create a 2 vSphere site with Linux VM's

[rmustafa]

Need a help for a planning step wise to create a 2 Site ( cloud computing -vSphere 5, ESXi 5 & vcenter)

Site 1: 6 ESXi 5 HV in a cluster, with DRS , vMotion (Vsphere Ent) & 10 Linux VM's   (Private IP) ,

From firewall, 10 VM's will be linked to different public IP (web services will be used in VM's)

iSCSI or NFS based Storage will be used in vSphere 5 cluster

VM's: web server, database server, application server

Site 2 : 6 ESXi 5 HV in a cluster, with DRS, vMotion (Vsphere Ent) & 10 Linux VM's  (Private IP)

From firewall, 10 VM's will be linked to different public IP (web services will be used in VM's)

iSCSI or NFS based Storage will be used in vSphere 5 cluster

VM's: web server, database server, application server

Now I have mutiple requirment

1.>what can I do to have a replica of site 1 on site 2

2.>Is it posssible to have a replica VM's on site 2 for failover use ? DR site

3.>Is it possible to have a Fault tolerance of VM 1 (site 1) on site 2, that might serve our purpose.

4.>If site 1 network is down , user can redirect to site 2 of same Vm's (web services)

My sole motive is to, user should now face a connection issue , if site 1 is down they should redirect to site 2 & (Site 1 & site 2 ) Vm's get replicated automatically.

Thanks.

This really depends on your exact requirements.  You can use something like Veeam Backup and Replication to replicate VMs or go as far as use VMware Site Recovery Manager to build a full blown DR scenario.  If DR is not exactly what you are looking for then you could look at load balancing.  Fault tolerance requires very low latency, as in sub-millisecond, so I would assume that this would not work for your design.

Are the two sites in the same L2 network? Do they share the same storages?

Otherwise FT cannot work.

Check last version of Veeam (or similar product) that has some features for VM replication.

Or consider VMware SRM5
