ESX is a completely different beast than workstation, or GSX for that matter. |
| 2 |
|
| 3 |
Good: |
| 4 |
- Very, very stable |
| 5 |
- The only real vmware software designed for server apps |
| 6 |
- Performance VM QoS for disk, cpu, network, etc |
| 7 |
- Easily run 30-40 VM's on a strong box w/ good mem |
| 8 |
- Deals with lots of NIC's assigned to different vm's |
| 9 |
- Per VM User Access Policies |
| 10 |
- Very nice realtime performance reporting |
| 11 |
|
| 12 |
Bad: |
| 13 |
- Dont use for apps that really need performance of |
| 14 |
dedicated boxes |
| 15 |
- Not cheap, especially if get all the management add ons. |
| 16 |
- Setting up some of the networking is more complicated than |
| 17 |
it needs to be. |
| 18 |
- Not very good w/ linux 2.6 kernel support yet (read, dont do it) |
| 19 |
- I don't find the rollback, and cloning functionality as useful |
| 20 |
as others. In fact, I've seen some vm's be corrupted if you |
| 21 |
select the "append" mode for disk writes, which creates |
| 22 |
a redo log that can get lost if the server hardware crashes. |
