The HP Procurve 2510G-24 and Cisco Catalyst 2960G-24TC can be used for small
setups where no inter-VLAN routing is needed.
On larger setups, both GigE ports of the XT2+ servers or/and several ports on the
XF2 are often used to increase the bandwidth or to allow redundancy. Since both
GigE ports of an XT2+ server cannot be used on the same sub-network, virtual
LANs need to be created. To allow the transfer of packets between the virtual
LANs, layer 3 switches are required. You need to select a layer 3 switch that is
able to route jumbo frames.
A switch of the Cisco Catalyst 3750E series should be used on larger setups as
they support jumbo frames, allow traffic to be routed between different VLANs and
provide stacking capabilities.
The following table gives an overview on the supported switches:

A layer 2 device can be used when all machines are configured to be on the same
LAN, when another layer 3 device is present to do the routing if needed, or when
no routing between VLANs is needed.

HP switches have a lifetime guarantee with next-business-day advance
replacement with no additional contract purchase.
HP switches are not compatible with Cisco's proprietary protocols (ISL, PagP,
PVST, etc.) which could be a problem for integration in some legacy Cisco
environment. However, such a case is quite unlikely to arise and most of the time
workarounds can be found.
The stacking possibilities of the Cisco 3750E series permit to have fully active
LACP teams for redundancy to the hosts.
