22nd Dec 2009 : I needed  a XenServer at home to work on some project for my company (Activlan), I didn't want a real server because it would be too noisy in my apartment :) So I was looking for a silent computer and I made my choice with the elements bellow : Case : Lian Li PC-V351B Power Supply : Silverstone Nightjar ST45NF - 450W MotherBoard : Asus Maximus II Gene Cpu : Intel® Core™ 2 Quad Q9550 Ram : G.Skill Extreme Series MQ 4x4096Mo PC6400 Dual Channel CAS6 Video : PNY Quadro NVS 295 PCI-E 16x (for another workstation #XD4) Hard Drive : Seagate Barracuda ES.2 S-ATA - 1000 Go - 32 Mo (x2) I though it would work fine, just some question were remaining : The network adapter on the Asus motherboard might not be compatible with XenServer and I did choose two hard drive to build a RAID 1 but I though XenServer wouldn't be able to recognize the sata RAID controller. I was right on the Sata Raid controller, it was too mainstream chip raid controller so I never got it working. The network card was fine I just got some issue with XenServer 5.6 and the checksum calculation, I had to disable the TCP Offload on the hypervisor (eq : not the vms). Hard drives, the Seagate are not a good product at all, I got 5 break down in less than 2 years, I will never buy enterprise class Seagate again. Then in june 2011, the motherboard died... 10th Jun 2011 : The motherboard is dead... Maybe it has been the source of all the recent system crashes I had... So I got to move on and chose a new motherboard. I chose Intel DQ67OW, with a new CPU an Intel Core i7 2600 which contain the virtualization instructions I missed with the previous CPU (VT-d). Case : Lian Li PC-V351B Power Supply : Silverstone Nightjar ST45NF - 450W MotherBoard : Intel DQ67OW Cpu : Intel® Core™ i7 2600 Memory : Kingstone 16GB 1333MHz DDR3 ECC Reg CL9 DIMM (Kit of 2) DR x4 w/TS Intel Video : PNY Quadro NVS 295 PCI-E 16x (for another workstation #XD4) Hard Drive : Seagate Barracuda ES.2 S-ATA - 1000 Go - 32 Mo (x2) for vms Hard Drive : Seagate Barracuda® XT SATA Revision 3.0 - 2 To - 64 Mo for vms Hard Drive…
