I have two VMware servers - ESX + ESXi. Two backup NAS boxes. The current NAS boxes are low-cost and unsuitable for running VMs from. Support NFS only. Slow.
My plan is to have a dedicated iSCSI/NAS for storing and running VMs. Two additional low-cost boxes for backup.
I'm looking for advice regarding 2 things really:
- Recommendations as far as VMware architecture/design for a smaller organization. Less than 20 Virtual Machines. 2 servers + 2 x 1.5 terabyte backup NAS boxes.
- A good NAS/iSCSI box with your recommendation on RAID config ...I would go with 6 or better.
I'm trying to design an installation that is both fast and reliable/redundant. If you have any experiences to share or your current configuration including network design ( switches, fiber ...etc ), I will be enormously thankful. I'm not married to this idea, so if you have a design not using iSCSI NAS boxes ...let er rip. Cost? Can we stay around $5,000 ( on top of already stated components )?
Links to info are welcome also.
Thanks for reading!
* UPDATE *
Thanks to all who responded. I began this post looking more at the NAS/SAN issue but am beginning to think that my main issue at this point is properly setting up our network for virtualization ...with all the equipment that entails. The slow NFS during testing is likely due to issues we've got on our network rather than protocol or device issues. We have a network consultant coming in this year and I now have more ammo to work with in getting it right.
Any other network examples, gotchas or advice is welcome. Thanks again.
