- if you're running more than ~30 ixp participants at any
particular exchange, you should run the sflow collector box on
separate hardware. We have noticed that the default freebsd
filesystem performance is significantly faster than default linux
ext3 for handling lots of rrd files.<br>
<br></div></div></blockquote><div><br></div><div>At BCIX, we run the sflow collector on the same box as the rest of the IXP Manager installation. </div><div>We run all IXP Manager components (MRTG, SFLOW ..) except the route servers on the same </div><div>bare metal installation with Ubuntu LTS.</div><div><br></div><div>Regarding handling of the rrd files mentioned by Nick , we placed them on a separate pair of server SSDs. </div><div>We used the hardware raid by the server (HP DL360p Gen8 with one <span class="s1">Intel</span><span class="s2">(R) Xeon(R) CPU E5-2620</span>) </div><div>to create a RAID1 for data protection and ext4 FS on top. </div>
