A grass-roots LAN with HardOCP present -- sign me up!

Working on updates across the board, focusing on the newer server for now. The onboard array controller is showing up as 2.0 and another add-on array card is showing 3.0 so I don't think it's BIOS related. Can't find any firmware updates for the Intel card. Will try moving slots but pretty...

Another update... seems the Intel 10Gbe XF SR's in BOTH servers are only negotiating PCIe v1.1, 1x which is ~2.5gbps (per hwinfo64). I'm not sure why since they should be v2.0 cards. Going to see if there are firmware updates for the cards.

Actually the 10G cards are directly linked between the hosts, no switch in the middle (..yet).

Update... picked up a couple of those Intel XF 10G cards but various iperf testing is only getting around 1.9gbps. Not sure if it's a PCIe or OS issue but going to keep at it. Any suggestions?

Should've read that post further, looks like they got more throughput after adjusting MTU and jumbo frames. Picked up a couple Intel E15729, will see how they do for my use case.

Those are nicely priced but looks like PCI becomes the bottleneck with those. Has your experience been better than ~2.5gbps?

Both servers have decent arrays but I've been testing exclusively with iperf to avoid any disk bottlenecks. I may get a couple 10G nics for each server but haven't worked with it much. Can anyone recommend a good NIC/chipset? I presume I'll need the cards, SFP's and cables to go directly...

Thanks for the feedback. There is an immediate need to transfer data but a longer term need to keep a subset of the data in sync between the servers. Thus temporary options like moving the controller/disks are not as attractive. Completely understood that I'll need a transfer protocol that'll...

My Google-Fu on this topic seems to be failing to produce a workable solution (if one exists). I have about 25TB of data I need to move as quickly as possible between two HP servers (Windows 2008 R2 and 2012 R2). 10G isn't a viable option right now. Server 1 - HP DL360 G6, NC364T Quad-port...

I think the Apple LED displays are extra problematic to glare because the glass cover isn't bonded to the panel. I guess that allows your eye to focus on the glare more easily. Either way those displays are overpriced. I'm using a few glossy HP 27" right now and although they are TN, they...

That all depends on the room. It's the trade-of for extra clarity. My room is setup in a way where I see no glare (no bright sources of light behind me). I've been in rooms where even matte displays have bad glare (even though it's diffused). Glare aside, I've always liked the crispness...

I may be wrong, but the only 24"+ glossy non-TN display I know of is the Apple LED displays. I've been wanting to go that route for a while but the mini-displayport gets annoying trying to work with a PC.

No splitters, I have two 6-pin leads directly off the 750w Corsair power supply to my primary XFX GTX285. The secondary video card is only to drive a 3rd monitor and is a XFX GT240 with no power connections. Each card works fine individually. The setup was working perfectly until I did a BIOS...

Did this ever get resolved? I have a different setup but the exact same symptoms and endless searching has not turned up any sensible answers.
