M500DC Tests/Discussion

FYI - Seller has not responded to me/claim at all... tomorrow Ebay will step in. So much for making it smooth and simple to return.

Ok, interesting. Did get some other goods from this seller and never had any problems.

Mine arrived saturday. Upacked only two and will flash one to the new firmware and leave another 'as is' for now. Then do some very basic fio-benchmarks / preconditioning this week on both.

 

[T_Minus]

Called ebay and they "forced" the return through giving me a return label to return items, and will refund when item is returned to seller if seller does not refund.

Ok, this is not very friendly
Had to do this with another seller recently, too. No answer regarding a return for more than 10 days.

Some quick benchmarks.

Drive is in steady-state and has ext4-fileysystem in a single, aligned partition.

Firmware is from IBM, Version MB2B.
Will flash current Firmware from Micron to another Drive soon to compare, and there is also a utility from IBM / Lenovo that, as i understood, would flash a newer oem-firmware on those drives. Will also give this a try.

Setup is 1 m500dc passed by ASR 8805 (no raid) to os.
Tests were performed on a Proxmox-Host, Kernel 4.2.8-1-pv

Seller replied and claimed to have "missed" my return request and stated he would have accepted it had he seen it... and he'll refund when items are back to him. Dropped them off today.

 

[_alex]

thats good, as said, never had problem with them.

did setup scst + srp today and got nearly the same numbers on the Initiator for a single Drive...
next is to deal with multipath / dm, then build an mdraid 10 with a mix of local and exported Disks and Benchmark again.

guess i'll not return when the other disks show the same numbers and Smart stays sane during testing different setups.

 

[_alex]

Had some time to do some basic tests with SRP and mdraid with two of them today.
Got this with 2 disks, read-iops and bandwidth more than 200%, thanks to raid1 (obviously reading from both disks).
Mixed tests with writes show about the same number like tests with a single disk, what is quite amazing

More Annotations about the setup below, in bold.
Guess i`ll setup a new post explaining how this exactly is assembled/can be configured soon.

My 18 drives are still with my forwarder company. It would be another month before i can receive them. Hopefully they are all good..

I will unwrap more of them during the next days, also hope there are all ok.
Did direct shipping from the seller, what was quite fast and paperwork for customs was done right. Got them delivered at home, no need to pickup at customs.

How's Everyone's drives doing? I just bought 12 of these. With HP firmware.
