PS I don't think we need raid cards though as they are a nuisance and linux can handle the raid1 nicely. 10GBE nic (it'll more likely be 10GBASE-T for us) is IMO essential.

Said that I'd like to understand if gridpp is going to buy these in one order for everyone or if we just have to conform to the model.

I'm fine with R610.

I think this is a fair analysis of the systems available.
Either box is an adequate client for Gridmon and PerfSonar.
I personally am agnostic to the network interface as it is upgradeable for sites which require 10 Gigabit connections.
However, I am in agreement that we should come to a final answer on this shortly.

Therefore, I would consider the R610 for these roles.

Can others comment on this if they feel that it is an appropriate platform.

Regards,
Mark

Therefore, could we have a quick discussion on which device we wish to buy
as we should have a standardised model across the UK for these devices.


So, to summarise:
- We like the idea of things like RAID, redundant PSUs, and
 hot-swap disks for the sake of keeping things up, and for
 the sake of peaceful contented sysadmins,
- We like 10Gbit cards,
- We don't want to gratuitously overspend on pointless stuff.

I think the R310 and R610 specs that I posted look reasonable,
but it would be useful to get quotes from Dell for the R310
with a 10Gbit Ethernet card (and confirmation that it's
capable of driving one at a decent rate, which is different
from 'it basically functions'), and also for an R610 with a
single CPU.

Is that fair, or does anyone want to suggest anything else,
because we want to get a final answer to this quite shortly
so people can actually go buy things.

Ewan
