Hey Guys
I am new to this forum but though to share some of my experience using this server to help other folks here as I bought from this seller alone 23 of these, Also it was me who reported the Supermicro Rails CSE-PT8L to the seller thinking of helping other buyers like you as the OEM is impossible to find, the supermicro is a tight fit and you will have to remove the small purple plastic stopper on the server inner rails for it to fit well, of course you will loose the stopper option at this point, but it gets the job done and of course way cheaper than $90 rare to find OEM, another alternative is to remove the inner rail and get any of the universal rails for HP G6 universal one, super cheap around $20-25 on ebay and works well too!
Now If you update from the penguin BIOS to the one listed for v1.1 which is R16, you will get E5-v4 to work even on revision 1.0 (tested) however server wont be rock solid stable on all OS, will crash from time to time, you will have to tweak alot in BIOS to get to stable it (This applies to v3/v4 regardless for BIOS R16 you will still need to tweak BIOS to avoid random crashes)
On the other hand the penguin BIOS (some machines would have R09 or R11) is way far more stable, my advise if you dont need to upgrade it dont specially if you will stay with E5-v3, the MOBO itself support v3/v4 only need newest BIOS to support v4 if you check here even for MOBO revision v1.0 E5-v4 is listed
For the SATADOM concern someone listed here, another work around, I am using a PCI that takes NVMe and M.2, and just using this sata port (there is 2 sata port "red one" next to PCI slot, Port 4/Port 5) and it normally get the power from PCI, something like this one will work
Amazon.com: Dual M.2 PCIE Adapter for SATA or PCIE NVMe SSD with Advanced Heat Sink Solution,M.2 SSD NVME (m Key) and SATA (b Key) 22110 2280 2260 2242 2230to PCI-e 3.0 x 4 Host Controller Expansion Card: Computers & Accessories or even skip this all together and add something like OWC ssd PCI and the board itself provide power through PCI to the extra SATA Drive, I have seen some of these by Starcom that can carry 2 M.2 and 1 NVMe in 1 single card
PCIe M.2 SSD (NGFF) Adapter Card | SATA Cards | StarTech.com, so if you combined the 4 caddies + the 3 starcom and 1 OWC you are ending up with 6 SSD and 2 NVMe working drives, there is also ASUS and Supermicro version of these that support RAID you will just need to do some search for it, I can help with model number as i own the supermicro ones if anyone need it
Lastly the BMC latest version on Gigabyte website version 488 if you upgrade it through dos or shell command will brick your server, they have an issue with this release SOCFLASH command that will flash the 128MB version instead of the 256MB to the ASPEED and ending bricking it, if you want to upgrade to it just use the mergepoint through browser and use the 488.bin file and you will be all set, I am sure you can take a backup of the penguin rom and bios prior upgrading but i didnt try honestly and also didnt try to downgrade so i cant confirm it.. I have 13 of these upgraded and 10 i never did, the 10 runs flawless while the 13 i had to tweak alot with several random crashes to get it to work well
I hope this help some folks out there, cheers
