Nice information before throwing the question.
NFS server is purposely for VM storage. For version earlier than 4.2, storage size limited to less than 2TB.
However, version 5.0 and above expandable over than 2GB. But somehow, the re-connection will be delaying and might become time out.
Especially during storage vmotion. This testimonial has been tested on 1GB FastEthernet LAN. It might be fine with iSCSI or any >2GB
Ethernet LAN. Cost implementation must calculate for at least 3 to 5 years ROI.Otherwise, considering Fiber Connection for long term use is more better.
1. To connect ESX to NFS server using FastEthernet Port
- Add additional hardware (network switch) in between ESX host and NFS server
- Or, directly connect from end to end host to server but require extra port and configuration
- Once ESX host boot up (but not boot from NFS, it will is use local disk) and ready to access via root,
- assign IP address to the port connecting from ESX host and to port connecting to NFS server
- each NFS server configuration is slightly different depend on server OS/controller
- configuration on ESX host can be done by command line or by GUI via vSphere Client at configuration tab > storage adapter (to scan/detect the connection) > storage (to assign LUN)
- the rest you may familiar with the GUI later on (user friendly)
2. Stable and good connection is depend on your environment, it may vary.
(refer notes above for Best Practice - this is not VMWARE.COM environment)
For my case, I have 3 ESXi hosts, 2 SANs fabric and 3 NFS servers with 30 VMs.And network teaming is alwasys recommended to get extra pipe
3. As mention in notes above, extra configuration and ports required if you are connecting the ESX host and NFS server directly.
(not recommended because network is main backbone of VM environment, once it stuck, you'll be jammed)
4. Also mentioned in #1., software or OS or controller is depend on your storage. It may provide their own or pre-installed with Microsoft Windows Storage OS. If you are using the open sources type, you may require more information and sometimes the features to manage the storage is too limited.
Therefore, consult with you storage vendor on this matter.
5. If you really want to save cost without considering furture expansion etc, all you have is quite OK. It just need more job, skills and know-how to manage and administer the things.
Wish you luck!
Suhaimim; thank you very much for your powerful answer Now I'm thinking that minimal 1 SAN server is a must have and NFS server is additional for backup or testing. SAN like more stable, reliable and give faster i/o performance.
I never used SAN servers. Please help me.
I think I need the following hardware;
1 SAN server
1 SAN SWITCH. (or direct connection between ESXI and SAN)
and for each ESXi server san???? Connection card. (is this normal FIBER ethernet?)
Can you please give an example hardware.
I understand that you NOT responsible for this advice. I need just more ideas. Because I have no idea about connection between ESXi and SAN server. If you give me some example hardware than I can understand.
