vicidial and software raid

[sshurtliff]

I've read on the forum before that vicidial in really any form is not viable with software raid. Is this true? Why is this the case? Any help is appreciated.

[williamconley]

it is entirely viable. but ONLY if you have a very very light load on your server. any heavy load on a vicidial server will cause too much activity for the software raid, the entire system will overload and crash horribly. But if you have a Powerful server and don't use it for more than 25-50 calls you should be fine.

Vicidial works fine on a software RAID, although you should never use a RAID5 software or hardware with a vicidial dialer.

[jamessmith]

what about RAID-6? or any other RAID level which uses parity?

[mflorell]

I'm sure it will function, but for software RAIDs we only recommend RAID1 or RAID10. Those are the only software RAID levels we ever use, for anything else we use a hardware RAID controller(LSI MegaRAID almost exclusively). RAID6 should ONLY be used for archive server purposes, not for anything else.

Since this thread is a few years old - I would like to know if Matt (or anyone) has any updated hardware RAID recommendation? That work with the current O/S (OpenSuSE Leap v.42.3 64-bit). I have a SuperMicro motherboard, it says that their embedded Intel RAID works with 42.2 - and then only with the footnote of "i-SATA/SATA (w/o RAID, AHCI mode)".

You had previously stated that you almost exclusively used the LSI MegaRAID controller -but - there appears to be a pretty large number of models out there. If you can give me some guidelines to help me narrow it down - I would REALLY appreciate it. Also - we are looking to do this primarily for fault-tolerance - however, performance is always a good thing too...so any configuration recommendations will also be appreciated (RAID1, 10, 5, etc)...THANKS!

We still only recommend MegaRAID hardware RAIDs for high-volume VICIdial databases. Any MegaRAID card is better than any non-MegaRAID card. The best MegaRAID cards have a cache and a battery.

We still only recommend RAID 1 or 10 for most VICIdial use. We only recommend RAID-6 for archive server functions.
