Upgraded my SAN

  I had built a SAN for my home virtual infrastructure a while back: http://mabination.com/threads/75809-Building-a-new-SAN
  
  I added a second raid card and 3x samsung SSDs in raid5. Was not expecting this level of performance:
  
  1M test

  64k test

  There's room for 8 disks on that raid card, so at some point in the future when the price of SSDs drops significantly more than it already has, I could probably fill it up and get retarded levels of performance. Will need to upgrade to a 10 gig network.
  
  I'm actually considering moving Nation into my house for hosting now that I have this kind of performance for the database...

  do it, whats the worst that could happen? [S]Nation blows up, your house explodes, data loss, server wipe?[/S]

  Those are numbers alright.

  Since he's doing raid 5, the worst that can happen in terms of data loss is one drive fails, he pops in the a new drive and the other drives automatically rebuild the lost data via parity.
  
  In terms of performance, this is pretty overkill for a forum isn't it?

  It's not only a forum that'll be on it. The storage is gonna be used by 2 hosts for various virtual machines.

  Or he loses everything in a flash flood, like I did (despite living at the highest point in the surrounding area well outside of any flood plains with a pump system in place to prevent it). Or a freak fire. Or a tornado. Or an earthquake. Or a simultaneous fire & flood caused by an earthquake/tornado.
  
  Worst cases are worst cases because they don't cover the typical 'one thing went wrong' scenarios :p
  
  Offsite backup > Raid 5 alone.

  Already have automated off-sites to a few places around the world, we would need to lose WWIII for nation to be permanently gone.
  
  Would also have local backups done with Veeam if I move nation over to my home infrastructure.

  Nation would probably run faster even off a regular hard drive if it were on a dedicated server/old computer lying around. The bigger issues is the connectivity to the net in terms of performance (need good upload, home connections usually suck for this) and availability (home ISP connections sometimes go down). You don't need too much throughput for a forum, since it's mostly text and images are cached, but the availability thing depends on a case by case basis. It's also a matter of whether your ISP will allow it--some of them don't approve of you running web servers off of residential connections.
  
  Personally? I think you should try. And backups are a non-issue.. pretty easy to do that.

  Not too worried about bandwidth, have 10 Mbps up, on average nation uses about 100 - 125 KB constant. The only big bandwidth bursts on the server are from backups, or downloads on my personal website which is gonna get moved to a 10$ VPS.
  
  I've also been hosting mail and web applications on here for a while, no ports are blocked. Stability is good, actually better than what's been happening at the datacenter on occasion. I don't mind it going down once in a while though if it costs me nothing per month to host and I remove ads for registered users as a result.

  It's not an issue of ports, but rather use policy.
