1. San is better, if cost is something you are dealing with look at DRBD, IET or I just setup NFS Server on Windows (SFU) and connected 3 fast sas drives and the box is screaming. That cost me an XP Pro license, on a 399.00 dell box. Running in NFS (not iscsi) suffers a little performance but adds a lot of functionality for backups/snapshots.
2. Yes, I usually hide the vmware tools tray icon and let them work on it first J 3. If you have enough hardware the overhead is minimal (2-4% in esx) If your server is under heavy load and very large you probably already have it on a san, how much overhead does the vmdk create? Vmware also has their own new Vmware scsi bus which is supposed to be screaming fast. 4. Yes, Shared access to a storage location in esx, or if you have the nas/san in place then its just 2 boxes running the o/s pointing to the san 5. Because you can create vswitch which is a lot faster and never hits the physical link of a network card, I will address teamed guests with that method, and then separate them if required due to overhead. If you have a client app and a SQL box, keeping them together is probably a good idea (if network latency is your primary concern). However, if you have that SQL in a cluster, you obviously don't want SQL2 on the same box ever. This is all setup in vmotion/DRS ruleset (sql1 and sql2 cannot be together, sql1 and www must be together etc etc) From: Roger Wright [mailto:rwri...@evatone.com] Sent: Monday, December 29, 2008 09:30 To: NT System Admin Issues Subject: Virtualization Questions Taking a look at the potential implementation of virtualization and have several questions: 1. Does/should utilization of a SAN have a direct impact on virtualization decisions? Is it better to go with local or SAN storage? 2. Do vendors who normally require a dedicated server accept a virtualized server as equivalent? 3. What type of servers (DB, Oracle, F&P, etc.) don't make good candidates for virtualization? I would think that SQL/Oracle would probably be least recommended. 4. Is clustering still possible with VMs? 5. What kind of logic determines the best combination of host/guests? IOW, is it recommended to put all F&P servers together on one host, or should it be a combination of F&P, DB, etc.? TIA!
