Alright! We've got a little extra hardware budget to use up before the end of the FY.
The main Kafka clusters in eqiad and codfw are both about to get a bit more usage as part of T157088. We don't believe that the increase in usage is enough to warrant buying new nodes, but it is possible that the behavior of message consumers may change that could cause messages to be read from disk, rather than from page cache. In anticipation, we'd like to use the hardware budget to replace the HDDs in kafka00.
These kafka nodes were procured in T145082 and T114191, and currently have 4 x 4TB HDDs. We'd like to replace these HDDs with large capacity SSDs. The larger we can get the better, but they obviously won't be 4TB.
This ticket is to get a quote for 24 large capacity SSDs for installation in the 6 main kafka brokers (3 in eqiad, 3 in codfw).
We understand that there is an industry shortage of SSDs, and have our fingers crossed that we could get these in time to use for the budget remainder. That means we'd need to have these delivered by the end of June!
