Product Description
The ServeRAID M1015 SAS/SATA Controller for IBM System x is an entry-level 6 Gbps SAS 2.0 PCI Express 2.0 RAID controller. The adapter has two internal mini-SAS connectors to drive up to 32 devices and supports the same base RAID 0, 1, and 10 feature set and drivers as the M5000 series controllers. With the attachment of the ServeRAID M1000 Advanced Feature Key, the ServeRAID M1015 offers the option of RAID 5 and SED Encryption Key management, while still being sensitive to administrator cost concerns in an entry-level RAID environment.

I came across this IBM M1015 new at a great price on Amazon so I bought it. Online users review it pretty highly. Amazon like always has been great. The card arrived pretty quickly. It came with low profile and regular brackets, manual, and CD. It doesn't come with cables. The cables can be had for pretty cheap online.
No driver installation was needed in Ubuntu. The installation went pretty quickly with no issues. I replace the Supermicro card, attached drives to it, and flashed it to LSI 9211 IT (straight pass through) mode so it just acts like extra ports. The other modes allow setting up RAID drives. My NAS is running a software RAID so I don't use the card's onboard RAID functions. The hardware key to activate RAID5 can be had for pretty cheap on eBay if you need it.
The M1015 has been great so far. So far it has been rock solid and fast. There has been no bit corruption that I have seen like with the Supermicro card. The drives on it are as fast as the ones on the onboard ports. I have plenty of ports if I want to expand in the future.
Amazing how a name changes everything. Often IBM includes these as a basic controller in their servers and they're swapped for higher cards, leaving the market flush with these.
I personally am using these each in ESXi whiteboxes. These cards fully support iommu with an appropriate board and caned be properly passed to virtual machines. That alone makes these
cards worth it!.
One important thing to note, is when buying cabling, make sure you're getting a SFF-8087 forward cable, this is important as reverse cables wont work!
I didn't really use the original firmware or raid card bios setup too much, so I can't really review on that. However, the ability to use another firmware that would work is definitely a plus for me.

A few weeks later, once I was holding it in my hands, I figured I would just run it in original mode and cross flash it only if I really need to (since cross flashing comes with the risk of breaking the card).
The problems started when I connected my card to my 3 yr old mainboard to a Computer running Ubuntu 14. I was not able to get the original card working and decided to cross flash it. This resulted in me having a non-booting PC due to outdated binaries from the cross flashing process which caused my card to not being able to install any firmware at all. Long story short, I spent the next 6 hours of my weekend trying to fix everything.
What worked in the end was getting the MB to boot into UEFI and flashing the new FW from there. Also I made sure the MB is running on the latest BIOS and managed to chroot into my Ubuntu installation and install the latest LSI drivers.
To conclude, after a very lengthy process to get the card running in the first place, I am more than happy with its performance. I was using a very cheap 4 port SATA controller before, which peaked at a 10MB/s performance (1 disk only) before dropping to 800KB/s after a few hours. With this card I'm getting full speed SATA access, but then again I'm using just one disk so far.
I would recommend this card to anyone with decent computer skills, since it can be tricky to set up, but offers great performance.

Only negative is that it came without the bracket.. The picture had one and the description didn't say it would be bracketless. Annoying. But I'm still somewhat satisfied.
Ich benutze den Kontroller hauptsächlich als crossgeflasheden LSI 9211-8i (Da die Kontroller identisch sind, nur anderes BIOS) im IT Mode. Damit wird er ein reiner HBA Kontroller.
In diesem Modus schlägt er alle Konkurrenten in der Preisklasse um meilen und OnBoard Chips um Lichjahre.
Jemand der ernsthaft ein Software Raid aufbauen will sollte hier zu greifen. Zu meinen Z67 OnBoard chip merkt man den unterschiedlich deutlich.
Im normalen Betrieb von Festplatten ohne Raid oder sonderlich große Beanspruchung wäre dieser Kontroller aber übertrieben.
Jedoch sollte man ihn in erwägung ziehen, falls man seinen Rechner mit Sata3 Ports aufrüsten will oder mehr Sata Ports benötigt.
Jetzt kommen wir zu den Minus Punkten:
Als HWRaid Kontroller, taugt dieser Kontoller leider mangels Cache nicht.
Raid 5 ist extrem Träge, ein Rebuild dauert ewig. Raid 0 und Raid 1 ist befriedigend, jedoch auch nicht perfekt. Falls man also ein HW Raid in der heutigen Zeit noch aufbauen will, sollte man zu einem besseren/teureren mit BBU und Cache tendieren.
Ich setzte 2x Kontroller in meinen Server ein. Softwareseitig habe ich erst Raid 5 von MS und nun Flexraid (tRaid) in Betrieb, was auch wunderbar funktioniert.
Festplatten und SSD sind Bootbar mit diesem Kontroller, ebenso als Raid verbund (wovon ich jedoch abrate).
Optische Laufwerke sind nicht ansprechbar.
Da der Kontroller als HBA einwandfrei funktioniert, dabei sehr performant ist und die Preis/Leistung einzigartig ist, gebe ich dem Kontoller 4/5 Sterne.
