dell-r710

We bought several 3T SAS hard disks want to use with our Dell R710 server. But we found our R710 can't recognize the 3T hd, and then we dig out the raid card is PERC 6i which doesn't support it.

Contacted with Dell that H700 and H800 support 3T hd, thought we can buy a H700 , but the SAS cable is not available in the market right now.
And it seems very hard for us to change the raid card, also no suitable tools to tease the special screws.

So I want to know if any other method to use these 3T hds instead of putting them in the warehouse?

Can I low formatting it to 2TB, and plug it into Dell R710 to use?
Or a SAS to USB adapter to use it as USB external disk?

I just want to use them by Dell R710 even external.

I've called Dell twice to try and clarify this basic (or so I thought) question, but I've had two different answers so far. We have a Dell R710, and a Dell R720. Does DRAC come installed by default on either? Dell said it comes build into the motherboard on the R720 but the second time I rang, they… >>> More

When the partitioner runs it fails to create / for some reason. I then tried just setting up a simple raid 1 with… >>> More

Dell R510 vs R710

as seen on Server Fault - Search for 'Server Fault'
Hello, the Dell R510 and R710 can both hold regular configurations (e.g. X5650, 24 GB RAM, etc.) and these usually come out to about the same price. Is there a particular reason why one would choose the R510 over the R710 or vice versa? There really appears a lack of differentiating factors. The… >>> More

I have two R710 servers with similar configuration. One in my office has MD1220 attached. Another one in the datacenter of my hosting services vendor has MD3200. I'm getting significantly worse throughput from MD3200 at my vendors setup. I'm mostly interested in sequential writes, and I'm getting… >>> More
