Hi Stackers !
This is the thing, today we have a 24 datanodes (3 copies, 90TB
usables) each datanode has 2 intel hexacores CPU with HT and 96GB
of RAM, and 6 Proxies with the same hardware configuration, using
swift 1.4.8 with keystone. Regarding the networking, each proxy /
datanodes has a dual 1Gb nic, bonded in LACP mode 4,
Are you seeing good balancing of traffic across the two interfaces in
the bonds?
each of the proxies are behind an F5 BigIP Load Balancer ( so, no
worries over there ).
What is the "pipe" into/out-of the F5 (cluster of F5's?) and how
utilized is that pipe already? If it is running at anything more than
2.5% (5000/200000) to 5.5% (5000/90000) in the direction the GETS will
flow it will become a bottleneck. (handwaving it as 100% GETS rather
than 90%)

Today, we are receiving 5000 RPM ( Requests per Minute ) with 660
RPM per Proxies, i know its low, but now ... with a new product
migration, soon ( really soon ) we are expecting to receive about a
total of 90.000 RPM average ( 1500 req / s ) with weekly peaks of
200.000 RPM ( 3500 req / s ) to the swift api, witch will be 90%
public gets ( no keystone auth ) and 10% authorized PUTS (keystone
in the middle, worth to know that we have a 10 keystone vms pool,
connected to a 5 nodes galera mysql cluster, so no worries there
either )
So, 3500 req/s divided by 6 proxy nodes doesnt sounds too much, but
well, its a number that we cant ignore. What do you think about
this numbers? does this 6 proxies sounds good, or we should double
or triple the proxies ? Does anyone has this size of requests and
can share their configs ?
