What I might even recommend is just adding 3 disks and going up to (2) hot spares as that will enable Maintenance Center
Hi Andrew,
In practical terms - do you think it is worth the hassle (on a small system) of convincing people to have even less usable capacity for the sake of Maintenance Center?
Say we look at FAS2050A with internal drives only: 10 drives per head minus 2 for parity, minus 2 hot-spares = 6 data disks left (12 in total across both heads).
If we run that scenario trough Synergy with 20x 450GB SAS drives & leave the default snap reserve, we will get:
Marketing Raw - 9TB
Net Usable - 3.8TB (base 10) or 3.4TB (base 2, i.e. something which will be genuinely seen from the host side)
Tough sell...
Regards,
Radek
