All interfaces on these machines are connected to gigabit ports on
switches (specifically, J8702A modules). There are three new
experimental-net switches (procurve3-procurve5) for these nodes, each
with approximately 240 ports. A fourth new switch (procurve1) acts
as the center of a 'hub and spoke' topology for the experimental network:
it is connected to the new switches and to the existing gigabit switch
(cisco8) at 24.4 Gbps each, and to the existing 100Mbps switches using
4Gbps to 8Gbps trunks.
Most nodes have 4 experimental-net interfaces, but some have 5.
The d710 nodes have their interfaces 'striped' across the switches:
each PC has at least one interface on each of the three
switches, so that large LANs can be constructed of all nodes, without
needing to use any inter-switch bandwidth. The layout is:
pc401-pc440: 4 interfaces: 2 x procurve3, 1 x procurve4, 1 x procurve5
pc441-pc480: 4 interfaces: 1 x procurve3, 2 x procurve4, 1 x procurve5
pc481-pc520: 4 interfaces: 2 x procurve3, 1 x procurve4, 1 x procurve5
pc521-pc560: 5 interfaces: 1 x procurve3, 2 x procurve4, 2 x procurve5
A fifth switch (procurve2) acts as the control network for the nodes.
Images and Kernel Support
Currently, the following Emulab standard images work on the machines. Officially supported images are highlighted:
Older FreeBSD and Fedora images will not work on these machines because
they require a newer NIC driver that supports the Broadcom 5709
chipset. FreeBSD 7 and up, and Linux kernels >= 2.6.22 (although 2.6.20 and
up may work), should support these NICs.
Limited bandwidth to other node types. Until we update the software
on our Cisco switches, we cannot "bond" links with the HP
switches. Hence, the experimental interconnect is limited to "only" 10Gb
via a link from cisco8 to procurve1. Likewise the control network has a
single Gb link between cisco2 and procurve2.
No FreeBSD virtual node support. Virtual node support is provided
through OpenVZ, allowing Linux-based virtual nodes. There are no
current plans for providing jail-based FreeBSD virtual nodes.
No control net firewall support. For one utterly obscure reason,
these nodes cannot be control net firewalls. This will be fixed in the
