We want to migrate our existing traditional infrastructure to a virtualised one. Our 5 Dell poweredge servers are several years old, and will fall over at some point plus we need the flexibility to deploy new servers to test the IT solutions we sell.
We have quite a basic setup of an AD domain controller / file server, exchange 2003 server, SQL 2000 server, web server and an extra server running anti virus management, network monitoring, and some other minor apps. We have 5 employees and on a daily basis, they use outlook email and a web based CRM. Our customers use our webserver. We plan to upgrade to the latest SQL server and Exchange. Our existing 32bit servers have held us back to date.
We have a quote from Dell for
2 x R510 with 2 x Xeon E5507 processor 24Gb RAM 250Gb SATA HD to act as hosts
1 x R410 with 1 x Xeon E5507 processor 16Gb RAM 250Gb SATA HD for vCenter Server
MD3200i iSCSI SAN with 450Gb SAS x 12
VMWare vSphere 4 Essentials Plus
We have had some performance analysis conducted by Dell on our existing servers and they assure us the above more than meets our requirements.
We also have from our existing infrastructure a Netgear GSM7224 24 port layer 2 managed switch, a Watchguard Firebox x550e security appliance and a Mitel CS5200 IP phone system.
Our current infrastructure has all servers on the same subnet, with some servers published to the internet. External DNS is provided by our ISP. Our employees connect via VPN to the watchguard firewall to access some of our internal resources including the phone system and exchange.
I am totally new to vSphere, but have experience of VMWare through workstation and server, I'm also new to SAN technology.
I've got a very rough idea how a virtualised setup might look, with our servers running as VMs connected to a virtual switch and that connecting through to a physical network port to the outside world for connection to the firewall.
I'd appreciate if someone could provide some feedback on the equipment spec and also the basics of networking up a 2 host environment to a SAN to provide HA, plus exposing the virtual subnet to external hardware i.e. connecting the IP phone system and firewall.
Our switch is VLAN capable, so can we have the storage traffic and that internal subnet on the same switch?
Also, I'd appreciate some best practice guidance on setting up the storage for the different types of servers we have, i.e. SQL and Exchange
