Subject: [Lustre-devel] Moving forward on Quotas
Date: Sun, 01 Jun 2008 10:44:27 +0800 [thread overview]
Message-ID: <C4682E0B.561F%peter.braam@sun.com> (raw)
In-Reply-To: <92825021-D566-4805-9297-5EFBD3260D73@Sun.COM>
That the total number of quota RPC's made by all OSS's (up to 5000 of them)
should not exceed something like 1/3 of this, based on today's hardware,
otherwise quota traffic will slow the cluster down.
We have seen big servers do 15,000 updates/sec sustained, so that is a
measure we can use at the moment.
