+
+h3. Run keepstore as a supervised service
+
+We recommend running Keepstore under "runit":http://smarden.org/runit/ or something similar, using a run script like the following:
+
+<notextile>
+<pre><code>#!/bin/sh
+
+exec 2>&1
+exec GOGC=10 GOMAXPROCS=<span class="userinput">4</span> keepstore \
+ -enforce-permissions=true \
+ -blob-signing-key-file=<span class="userinput">/etc/keepstore/blob-signing.key</span> \
+ -max-buffers=<span class="userinput">100</span> \
+ -serialize=true \
+ -volume=<span class="userinput">/mnt/keep</span> \
+ -volume=<span class="userinput">/mnt2/keep</span>
+</code></pre>
+</notextile>
+
+The @GOMAXPROCS@ environment variable determines the maximum number of concurrent threads, and should normally be set to the number of CPU cores present.
+
+The @-max-buffers@ argument limits keepstore's memory usage. It should be set such that @max-buffers * 64MiB + 10%@ fits comfortably in memory. For example, @-max-buffers=100@ is suitable for a host with 8 GiB RAM.
+
+If you want access control on your Keepstore server(s), you must specify the @-enforce-permissions@ flag and provide a signing key. The @-blob-signing-key-file@ argument should be a file containing a long random alphanumeric string with no internal line breaks (it is also possible to use a socket or FIFO: keepstore reads it only once, at startup). This key must be the same as the @blob_signing_key@ configured in the "API server's":install-api-server.html configuration file, @/etc/arvados/api/application.yml@.
+
+h3. Set up additional servers
+
+Repeat the above sections to prepare volumes and bring up supervised services on each Keepstore server you are setting up.
