In some cases the stop-chunking directive contained an extra hyphen, remove it so that the directive is effective. Change-Id: I4972aea3e0c9ee8a85718b47ca5b93f1b68329b9

<td><para>The amount of disk space depends on how much
|
|
you can fit into the rack efficiently. You
|
|
want to optimize these for best cost per GB
|
|
while still getting industry-standard failure
|
|
rates. At Rackspace, our storage servers are
|
|
currently running fairly generic 4U servers
|
|
with 24 2T SATA drives and 8 cores of
|
|
processing power. RAID on the storage drives
|
|
is not required and not recommended. Swift's
|
|
disk usage pattern is the worst case possible
|
|
for RAID, and performance degrades very
|
|
quickly using RAID 5 or 6.</para>
|
|
<para>As an example, Rackspace runs Cloud Files
|
|
storage servers with 24 2T SATA drives and 8
|
|
cores of processing power. Most services
|
|
support either a worker or concurrency value
|
|
in the settings. This allows the services to
|
|
make effective use of the cores
|
|
available.</para></td>
