Summary: been running vmware esx 4.1, been working great
Pros: have had this model for over 2 years, no problems
Cons: you have to provide "cons" for a product, ok sure, its low profile- just be sure you get low profile add-on cards; also the device has slots for 8 drives but mobo only has 6 ports- not that it matters cuz I'm not using the built-in sata.
Summary: I'm buying 5 more, so you know I like them. Supermicro has always been quick to RMA motherboards when purchased in a server. I wish Newegg stocked the IPMI option card.
Pros: I've had two of these running for over a year. Rock solid with 2 six core Xeons. Very fast for server type loads.
Cons: Has 8 SATA trays, all 8 have power, but only 6 are connected. So buy a cheap PCI-E/SATA card if you need 8 SATA running. Weighs as much as a large rock. Fill it full of disk drives and you will exceed 70 pounds, which means if you reship you will pay overweight charges.
Summary: The majority of our production servers are Dell or HP. This server has the same or better build quality. I was impressed with this server when setting it up. I may start using these in production more often. Linux (ubuntu serve 10.04) handled all of the hw fine.
Pros: Excellent build quality. Now set up with qty 6 3tb drives. Replaced my old bacula backup server. 2 more drives (OS) on mirror with 3ware sata raid controller.
Cons: Manual is incorrect about the location on the motherboard for cpu1 and cpu2 and memory. It is backwards. Also flashing red leds on 2 of the hard drive bays. Disconnecting unused cables (for sas) from backplane cleared the flashing red lights.
Summary: If you're using SATA drives, disconnect the sideband cable (which you only need for SAS drives) from the backplane and the red drive error LEDs will stop flashing.
Pros: Solid construction, great cooling design, fairly quiet, plenty of config options. I'm running several of these with x5650 processors 96GB ram, and 8xSATA drives in RAID5 config. It runs lots of VMs without any problems. Easy to configure, and if you're using the on-board RAID, choose the Intel BIOS, it lets you do RAID5. Just make sure you're RAIDs are < 2TB.
Pros: Bought it for a file server and put a bunch of disks in it; works great. Setup was really easy and haven't had any problems with it. You can also get Supermicro's IMPI 2 card for $60 and have remote management.
Pros: Bought this to be a proxmox VM server in our datacenter space. Put 8x2TB drives in it, 24GB ram, and 2 quad core CPU's and it's wonderful. I installed a 3Ware 9650SE-8LP raid card and the sata backplane is easy to re-fish the sata cables.
Summary: A little light on the BIOS settings, be careful with the disk detection when using an add-in RAID card.
Pros: Hardware all recognized by Proxmox, made a virt server out of this, 2 E5520s, 24gb Patriot 1066 RAM, and 4 Samsung 1TB drives in Raid10 on an Adaptec 5405. Couldn't be happier, easy to move around in the case and snake SATA cables for RAID array.
Cons: None, exactly what I expected out of a SuperMicro barebones.
