Oh, this is just for the main node? I'm not sure about the resources required for one... sorry.

hehehe, basically the function is that the Workstation passes the work to the main one, and the main node gives it to the rest of the Renderfarm...then all the frames are deposited in the main node for the finished render

I figured as much... just don't know what type of load that is. It still sounds like more RAM is going to be needed and a hardware RAID controller will be useful. You might want to look into a motherboard with dual 1Gb NICs capable of teaming.

RAM may affect, but since the whole renderfarm will have 2gb each node it is ok, also what is needed the most is a fast reading/writting time from the drives...that's why i thought RAID0 was the best...

If each node has 2GB, then one can assume the parent node would need more RAM since it will be managing data for multiple nodes. RAID0 would be the fastest but is the riskiest. What would the loss be to the company for lossing all data after running a 12hr+ render?

a lot, but i read that the risk is not high...

The main node is usually, but does not have to be, more powerful than the render nodes. Mainly due to the fact the main node is handling all the "outside" and "internal routing of" connections and the load balancing of the workload on the slave nodes.

If you want performance out of the raid array, smaller drives are better. You have to trade off capacity with speed. Don't even bother with the SAS drives in this instance due to cost. Yes they are more reliable and _usually_ faster, but you pay a premium for that performance/reliability.

I am currently building a storage sever for a customer (who resells it to his customer), and he spec'd out the Hitatchi Ultrastar 1TB (HU721010KLA330), with a LSI MegaRaid SAS/SATA adapter (84016E) with the battery backup option. The battery backup option is important in a configuration where the data is critical. It allows you to enable the Write buffer option which will increase the speed. The battery will make sure all data is written out to the drives in case of power failure or short interruption. For mission critical data, the battery is essential.

Do the cost/benefit.... how much will it cost the company if total data loss occurs? Getting a decent RAID5 controller and another hard drive will cost you $400 more. Is that that $400 worth the added protection or not?


If the following is true, spend the extra money for RAID5:
Probability of Failure * [(Data Lost Cost) + (Downtime Cost) + (Cost of Replacement)] > RAID5 Controller + Hard Drive + Slight Performance Decrease.

I would just get 8 of those 500 drives and go with a hardware raid controller that supports RAID 10.

Speed and backup.

Thanx for that info...but...
ok, that adapter alone costs 700 dolars...again not in budget...best will be like duckieho said...

so, i would get another drives of those and this:
but that one only have 4 channels...
