I'm a bit lost/confused. Where is your datastore if you're relying entirely on a virtual network on the host?

This is my lab It does basically everything I needed for the VCAP-DCA/VCP5/VCP5-DT(VDI)  AND MORE. I may do a better to understand visio tonight when I get home, essentially you just hook it up to a virtual switch, like you would a physical switch and attach to it via IP

Thinking about switching my home lab from iSCSI to NFS. Apparently NFS performance is significantly better on the Synology NASes. I have to actually partition my network with VLANs to force traffic through a specific NIC/VMkernel then, which I don't have to do with iSCSI.

So, I'm thinking about doing the following: 2 of the servers are for home lab, the third one will be where I consolidate my current poo poo to for home entertainment, etc. The 5 DP NICs, 1 for each server, 1 for my NAS, 1 for my backup NAS. One thing I really want to test is iSCSI MPIO over Gig-E since it's likely something we're going to implement at work in the near future. Any problems with it? edit: and the mic you can ignore.

The cheaper ones were only $10 cheaper, didn't have free shipping and shipped from a third party. Even Kingston is $150 for some reason.

I'd personally get this http://www.newegg.com/Product/Product.aspx?Item=N82E16859106267R You'll get a fully featured xenon proc, 2more mb of L3 cache, and you can jam diffrent size DIMMs in and get the same dual-channel speed. Also you can step up to ECC ram. The only thing you don't get is hyper threading. E: its not nearly as sexy as the shuttle, i'll give you that. incoherent fucked around with this message at 09:04 on Sep 28, 2013 |

Also, a heads up to anyone that wants to buy those from Amazon, they don't come with low profile brackets, but I emailed the seller (AMTECH) and they threw them in for $10 each (I only needed 2).

Why dual instead of quad port? Quad is the default when I order a GbE network card for a server

Quad is a bit overkill for testing machines. Very nice to have but its like 200 bucks for the bare bones one. If you dig hard you might be come up with an older version on the cheap, but it be PCI. Also that card was 76% off. Open box or not

luminalflux posted:Why dual instead of quad port? Quad is the default when I order a GbE network card for a server You can get really cheap Intel dual-port NICs that are super compatible with VMware; quad-port NICs tend to be more than 2x (sometimes as high as 5x) expensive.

I've found that getting a switch for less than like 10 grand is the bigger impediment to dicking around with 10Gb. Looks like Netgear makes an 8 porter for ~$1k but that's more than I'm willing to spend on one piece of gear for the home lab.

Unless you're running performance simulations in your lab on hardware that's nearly identical to the production hardware, is there anything you can't do conceptually with GigE that you can with 10GigE?

Malcolm XML posted:Are there 10gbase-t nics that don't cost $500 out yet? I kind of want to use a few to make a tiny home data center to test out my work stuff What do you need 10Gb for? Genuinely curious. You could always switch in ram with the VMXnet at +/- 10Gb/s depending on the HW backing it. Is 125MB/s not enough? You can look into some cheap rear end 4Gb/s FC HP HBA's and switches for fairly cheap.

Anyone here been successful in setting up a client/server configuration for GNS3? Trying to get something setup for the junior guys at work, without them having to run GNS3 on their work desktop or use RDP/VNC to a server in the lab. I am going based off this documentation: http://www.gns3.net/documentation/gns3/client-server-and-multi-server-mode/ My assumption / build for them has been a beefy RHEL6 box in the datacenter that has all the images loaded up and they should be able to just launch the GNS3 gui locally and connect, but I am not sure if I am missing something.

Anyone have any suggestions on getting a cheap enclosure or rack to use for my home lab? I want to be able to mount some cisco gear and my dell cs24-ty and my low power file server? I was also going to build or buy another server to use as a NAS and I want to complete the rack with a rack mounted UPS. I just am trying to avoid spending a ton of money on a rack or enclosure and I am not even sure what kind I need.

I don't really have any suggestions for buying one, but if you live near a university I would make some inquiries. They're always throwing out 19" racks of various sizes at the U where I worked. I've got a few racks in reserve just because I claimed them when I found them on the loading dock.

Comradephate posted:I'm not at all familiar with infiniband offerings. Mind linking example products that you'd suggest? Go on eBay. Look for Mellanox HCAs (QLogic HCAs are also fine), CX4 cables, and an infiniband switch (QLogic, Mellanox, maybe Topspin or Cisco). Any PCIe HCA you see should be at least 10gb. You can get 10gb (8gb effectively, because it probably won't be FDR) for ~$25, and dual-port HCAs for $40. 10gb is old hat in the Infiniband world. It's actually that simple.

Am I stupid for wanting a Dell C6100? I feel like out of all the cheap servers, for a home lab you really cant beat it when you can get one for as cheap as $650. It gives you the option of using 1-4 nodes which would be really helpful and they are decently powerful. The only downside for me is the power usage, I heard it uses 300-600 watts depending on load. I am almost tempted to buy one and colocate it with one of those bargain places and they said I could include a switch as long as it is under 4ul. However I am pretty sure that it would use more then 2amps on a 208v line.

However I am pretty sure that it would use more then 2amps on a 208v line. It's a 65-80 dba server that draws an amp or more, and you can build two brand-new 8 core nodes with 16GB of memory each for the same price. If the caveats of the C6100 (noisy as all get out, draws power like mad, 5 year old CPUs) don't bother you, you'll have a hard time beating it for the price. If you want something you can run at home, I'd advise building cheap Zambezi boxes. But this is probably the fifth time I've said this in this thread and not everyone agrees. It may make sense for you if you can live with the drawbacks.
