Mutiple switches and NICs for redundancy. Google multipathing in ESX John W. Cook Systems Administrator Partnership for Strong Families
From: Richard McClary [mailto:[email protected]] Sent: Tuesday, March 13, 2012 11:54 AM To: NT System Admin Issues <[email protected]> Subject: RE: New to virtualization I’m really just getting started here myself, but… VM NICs connect to real ESX NICs, and you will need some ESX NICs for redundancy, for management, for a possible DMZ in the future, etc. Oh yeah – the ESX hosts need NICs for the iSCSI connection to the datastore. Figure on getting some dedicated network switches as well and work out some subnetting (so the management, kernel, and other connections are not a part of your main LAN). NetApp makes good SANs, and their support is great! (A drive starts to go bad, and you get an email from support asking where to ship it to, etc. Sometimes that is the first and perhaps only indication something is going wrong.) From: David Mazzaccaro [mailto:[email protected]] Sent: Tuesday, March 13, 2012 10:04 AM To: NT System Admin Issues Subject: New to virtualization Hi all, I am starting to investigate moving our aging network infrastructure into the virtual world. ~ 10 servers, 6-7 years old Windows 2003 domain Exchange 2003 Citrix 4.0 farm ~190 users After some initial discussions w/ a reseller, here’s what they are recommending: (3) DL 380 G7 servers (to host the VMs) ~$18,000 (1) Net App FAS2240 (this is the SAN that would host 12 600GB drives of storage for the VMs) ~$20,000 VMWare essentials plus kit (VMware software) ~$5200 (3) MS Windows 2008 R2 Enterprise (this would allow the 3 HP servers to run 4 Windows 2008 VMs each) I guess the way it would work is that the VMs would reside on the SAN, and the 3 hosts would call up the SAN to load each VM utilizing the host’s CPU, RAM, NIC, etc.)… right? I have meetings scheduled w/ 2 other vendors, but verbally both have started the conversation along the same path as above. Being very new to VM, does the above scenario seem to make sense? It is hard for me to imagine all that traffic going between the SAN and the host servers w/o creating a huge bottleneck (over gig Ethernet) Do people recommend virtualizing every server? Domain controllers? Exchange? Citrix farm (4 server)? Shouldn’t something be left physical? Is 7 TB of storage enough (probably only 3 usable after array config)? Is the net app a decent appliance? $20k sounds cheap to me… I have done a little more reading, and from what I understand w/ 3 Windows Enterprise licenses, I would be limiting myself to 12 VMs. However, if I went w/ 3 Windows Datacenter licenses, for a small increase in price - I would get unlimited VMs? Which would allow for actually having a testing environment, and better patch deployment?
