Performance to 4x 3TB Seagate 7200RPM with Raid 5 Iscsi passthrough

[wreedps]

Hello,

I have 4x 3tb Seagate 7200 RPM drives in a RAID5 on a LSI controller in my FreeNas box. I am passing that volume thru Block Iscsi to my VM hosts.

I am seeing about 144Mb/sec read and 110Mb/sec write.

Are these good numbers? I am just experimenting now.

 

[wreedps]

Anyone have an opinion? Just looking for thoughts.

 

[pirateghost]

I don't understand what this has to do with freenas

 

[wreedps]

Ummm because I am running a FreeNas box? Its OK if you are just waking up.......

 

[pirateghost]

You said, raid 5 on LSI controller. You shouldn't be running freenas on top of hardware raid. That's the biggest no-no in zfs.

Your post made no sense to me. I don't see where freenas sits in this instance.

 

[wreedps]

I am passing thru the Raid5 to Vmware. No ZFS.

I am using this hardware RAID until I can build a new server without hardware raid.

 

[pirateghost]

You're passing the raid5 through to VMware??

Then where does freenas sit in all this?

 

[wreedps]

Ummmmm Freenas is passing thru the ISCSI block to 2 VM hosts? What is so hard to understand?

 

[pirateghost]

Sigh.

You're using freenas, but not using any of the nas features or storage redundancy and data protection. Got it.

Basically you're not utilizing freenas for anything but an iscsi connection....

 

[wreedps]

Exactly. I built this box 2 days ago to begin to experiment with Freenas.

Sigh.

As I said I will be moving to ZFS and NO HARDWARE RAID in the coming weeks. I am just wondering if I am getting good performance in it current state.

Sigh. I cant get a straight answer to my simple question.

Sigh.
Sigh.
Sigh.

OP,

I think you might be missing what pirateghost is saying. You're doing things FreeNAS wasn't designed or supported to do, and there aren't going to be any persons here doing that, so you'll not likely get any help if you run into any issues.

I don't think anyone can say if your basic rates are good or bad. I don't think it sounds unusable, but I don't know what you're trying to do. It doesn't really matter either since you're just throwing some stuff together to see what happens.

Read the forum rules, the Newbie Guide posted by CyberJock, then the manual.

I don't see where you said that at all....if you want feedback, you need to provide more info and context

 

[wreedps]

I will be removing the raid controller soon as I just got my hands on a LSI 9207 HBA. I am just trying to build a large stable FreeNas box to run my 25+ Windows Server VMs against.

 

[pirateghost]

oh I see where you EDITED your post to make the comment about changing out an unsupported hardware raid to use zfs....

but whatever numbers you see now do not reflect what your setup on ZFS will be....so why do you give a flying flip what your speed is now?

 

[wreedps]

I edited the post to say I was using Freenas my friend. I posted later I am removing the hardware raid.

Just wondering if they are good numbers is all for 7200rpm desktop drives...

I have your full edit history....I know exactly what you put in your posts.

 

[wreedps]

I am very happy for you!

Please take your snark out of here. You didn't provide enough info in your original post and got called out on it. It took several posts to even understand what you were talking about.

Just drop it and move along.
