Comment on Super Micro IPMI Firmware – X7DWT-INF by rgunther

Not really, the IPMI is not so great. Especially now with more browsers disabling Java.

We have mostly converted to servers running Intel AMT on vPro processors, it works much better.

Comment on Testing NO RAID vs RAID 5 vs RAID 10 by Adam Satern

Be mindful of hard errors which are the reason that RAID no longer lives up to its original promise.
If one of the drives fails, then during the rebuild if you get an error – the entire array will die.

SATA drives are commonly specified with an unrecoverable read error rate (URE) of 10^14. Which means that once every 12.5 terabytes, the disk will not be able to read a sector back to you.
