EqualLogic Replication
Posted on March 31, 2010 by mellerbeck
So in my eternal quest for DR goodness these are my initial stats so far. I have been testing our four most heavy hit servers. (These have not been really optimized for replication, need to figure out how to lower the changed bits) For the last 11 hours Kronos SQL DB server 9930 MB Exchange [...]

EqualLogic feature request, veeam as well
Posted on March 29, 2010 by mellerbeck
I have been investigating using veeam for backups of our Virtual Machines. It can do a direct SAN backup which is pretty cool, but it makes me nervous that you have to give read\write access to the volumes that it talks to (When you are using equalLogic, Veeam only needs read). I would like it [...]

Hurting you VM performance using SCP (or fast SCP)
Posted on March 22, 2010 by mellerbeck
I never knew this: Using SCP/CP to place the VMDK on the VMFS volume can cause poor disk performance for the VM, vmfkstools properly allocates the space to prevent this. *** vmkfstools allocates all space at once and then copies the data, a “normal” copy (cp, scp, …) allocates the space while copying. This behavior [...]

Clearest Paragraph I have read yet on configuring STP for EqualLogic
Posted on March 16, 2010 by mellerbeck
From this guide http://www.equallogic.com/resourcecenter/assetview.aspx?id=9259 4.2.3 Pay Attention to Spanning Tree In our test configurations we disabled Spanning Tree Protocol (STP) on all switch ports connecting to end devices (the server and storage controller NICs). We also enabled the “portfast” setting on those switch ports. Since NIC and storage controller ports are end points they cannot create loops. Thus you [...]

Replication is easy, DR is hard. Take two
Posted on March 12, 2010 by mellerbeck
So some follow up on my research. I wish there was a guide compiled with all this stuff, for us newbies it is hard to consolidate it. It does appear like it is reasonable to put your guest OS paging file on a separate volume. This post http://communities.vmware.com/message/1308892 1. add disk – set to persistant [...]

Replication is Easy, DR is hard
Posted on March 11, 2010 by mellerbeck
So here is the situation, we are looking into setting up our DR site. Of course there are about a thousand ways to go about doing this. The most basic approach appears to be SAN replication. We love our EqualLogic SAN’s but the Delta that they transmit appears to be very heavy. People that I [...]
