Replace asw-c5-eqiad or asw-c8-eqiad with EX4550
Closed, ResolvedPublic


All the memcached servers are on asw2-a5-eqiad, which is currently a SPOF. The
situation for the Varnish servers is similar, and they need 10G as well.
Let's move half the memcached servers, and half the varnish (10G) servers to C5
or C8, with an EX4550 as part of the row stack.
Tampa has some EX4550s now, we should ship them over. What we don't have, we
should order ASAP.

rtimport set Reference to rt5106.

No progress in the ticket since May, despite the relative urgency of this (Mark's request mentioned "ASAP"). Racktables seems to indicate that this actually hasn't happened.
Where is this blocked? Is it hardware or someone (who?) doing the work?

-- We have an EX4500 in place on c8 now....Last chat with Mark was to replace
the 4500 with a 4550 but we have the varnish servers there now so a plan needs
to be made on swapping out the switch.

asw-d6 - ex4550 - empty
asw-d7 - ex4550 - empty

asw-c8 is a 10G switch now (4500, though). As mentioned above, we also have row D nowadays.

The other half of this task, the memcached servers reshuffling, is covered by T83551. Resolving.
