Hello all,
I have 1 PowerEdge R610 Production server that host and all my company websites (12 websites on wordpress, ticket, crm), database and email.
Until not so long ago, I was quite happy in my little bubble and that setup.
Since registering here in 2011, I can see that I have learned a lot through this forum and I am now in the next phase in my tech life and realize that I am a sitting duck and my setup is a disaster waiting to happen.
If I loose the server, I can restore it from backup but I will suffer a great data lost as the backup are nightly and a serious 4 - 6 hours downtime for the restore process to finish.
My plan is to create a HA environment where I can cope with hardware failure and minimize single point of failure.
I have at my disposal:
10x Dell PowerEdge R610
2x Dell PowerVault MD1200 with 12x 3TB
2x Dell PowerConnect 5548
1x Dell PowerConnect 5324
I got the whole lot for just under £1000 so I figured I could resell if it was not good for me.
I am looking at a long-term solution and trying to understand how to setup the above hardware.
Will I be better to put 6 large disks inside 2x R610 to make it 2 sans in failover and connect the rest of the server via iSCSI or use the 2x MD1200 that I have via DAS? Aternatively, I could attach 1 R610 to the MD1200 and use iSCSI via the R610.
I tried to look online and it looks like I can only have a maximum of 2 hosts attached to the MD1200. Is that correct or can I have more than hosts?
Which will provide better performance ZFS?
With the DAS, how many SAS card do I need to add to my R610? I have been looking at various schema and some use 1 SAS HBA per host and other schemas 2 HBA per host.
Thank you
