thanks for the request.
Apollo Systems are strait forward standard systems with typical standard raid controller.
So if you use big disks, Raid rebuild times are very high. To protect your backup data you should use Raid6 or Raid60. As Veeam do a lot of Random Write in many cases Raid 6/60 isn´t that optimal.
My recommendation for huge disks (above 1TB) or Nearline (7200rpm) is:
- Create a Raid60 with 4+2 or 5+2 (to address random write penalty at Raid 6)
- Use Apollo recommendations for Spare disks. 1 for each 20 at min.
- Latest Raid Controller Firmware usage
- Latest Raid Controller Firmware default block size settings are OK for Veeam. Maybe set it one value higher.
- Add at least 2 SSDs in Raid 1 and create a Smart Cache (use latest Raid controller configuration boot media to enable this).
- User forward incremental Veeam backup modes to process more data sequentially.
- Per VM backup chains can help to increase speed with that system
- Don´t use any Raid controller based dedup or compression (don´t know if any raid controllers are available for that system that support this... just in case).
A general recommendation for Raid Controller selection:
- use battery buffered controllers
- choose the best one that is available for the systems.
- More raid controllers help in case of performance.
