Buying New Hosts

We are looking for some information regarding host performance using different types of RAID.

Does RAID 1 versus RAID 5 noticeably affect host performance under the following conditions?

  • Host disks are used for the ESX operating system and storage of ISO files for quick access from the vSphere client to install software on virtual machines.
  • All virtual machines are stored on SAN storage and not locally on the hosts.
  • All data is stored in raw mapped LUNs and not locally on the hosts.
  • Virtualcenter is being utilized.

The entire reason for this question revolves around having more host disk space accessible for the use of ISO storage without impacting performance.

Yes we know mirroring is “faster” than striping.  We just want to know if anyone has experience with how much it affects host performance.

Thank you for your comments and suggestions.
