Array of memcached network servers, or unix socket pathnames using the PHP form (example) unix:///var/run/memcached/socket (for use with the memcached memory-based object store).

Note that beginning in MediaWiki 1.35.6, 1.36.4 and 1.37.2, when specifying a unix socket pathname, a trailing :port number must not be specified. It was ignored by the prior versions, but is now treated as part of the pathname.

Details

To use multiple servers (physically separate boxes or multiple caches on one machine on a large-memory x86 box), just add more items to the array. To increase the weight of a server (say, because it has twice the memory of the others and you want to spread usage evenly), make its entry a subarray:

$wgMemCachedServers = [
  "127.0.0.1:11211", # one gig on this box
  [ "192.168.0.1:11211", 2 ] # two gigs on the other box
];

You can have multiple wikis point to the same Memcached server, as long as each have different wiki-ids ($wgDBname ). Certain cache keys are intentionally shared in such a scenario, such as rate limiting stuff.
