Morning All

Have a 16bay storage enclosure with 32gb of ram and 16 x 2TB hdd's.
This enclosure is a supermicro 3u enclosure.

For some magical reason, the server keeps becoming unresponsive.
I did have freenas installed on it, i thought maybe i was being greedy with putting on freenas with such low ram.
However, the server was fine for 6months+, i then moved homes and put it (unused) in the rental for 3months.

I've had it running for 2weeks and every single day +-12hrs it becomes unresponsive and needs to be physically turned off and back on.
As we know, this isn't ideal for storage servers, hdd's or any server!

So last week i decided to format the server, used hardware raid (adaptec 5405) and install windows 2012 r2 only.
To my surprise(sarcasm), its still becoming unresponsive. The server currently doesn't do anything besides sit there with no programs running, still becomes unresponsive.

*clueless*

I then decided to transfer some data (+-1.2TB) to the new raid6.....again the server becomes unresponsive after about 500gb transfered.

Where should i start? what should i break first?

Server  Specs :
- 32Gb Ram
- Intel Xeon CPU E31240 @ 3.30GHz x 2
- supermicro x9scm-f MB

Check SMART status of all the drives?




Information wants to be free. The Net interprets censorship as damage and routes around it.

Lias: Check SMART status of all the drives?


All drives are good,checked them with freenas prior to removing freenas.

What is unresponsive?

Not responding to ping?

What is on console?

Does it accept keyboard input?

Any performance logging (i.e. to show CPU flatlining at 100%)

sorry, should of been more clear on that.

unresponsive = cant remote desktop, cant ping, no ethernet connection, screen is blank, kvm screen is black, keyboard doesnt work......yet the fans on the server are still going, the lights are flashing as if its on?

Hmm,

So you've already ruled out an OS issue.

Suspects would be:

1. Raid Controller and Storage Array
2. Motherboard/CPU/RAM combination

So is it possible to have the server running with a single disk or 2 on whatever storage is on the motherboard? So disconnect the raid controller and external disks?

If that freezes then it is possible bad RAM/bad motherboard component.
