Sun 7110 disk and network load

[cookie_monster]

Does my 7110 look busy to you guys? I'm just trying to get a feel for what figures I should look out for to let me know when it's under heavy load. I can see on the image below that some of the blue bars show quite high but I never see more than the cloud symbol. Some of the grey bars go all the way to the top what's the difference between the blue and grey meter bars?

Thanks.

I believe grey is the highest recorded figure and blue is the average

And to give you an idea of load this is our 7110 running a load of VMs/Home Directories/Whatever else we can throw at it

Thought that might be the difference our disks look quite busy but it seems to be coping. Then again your look like they've been flat out at some point.

It's certainly being kept busy that's for sure!

As far as I understand - cloud symbol is not really megabusy it just means it is being used a bit. Are you running a database on there as you have quite high iops compared to your network usage?

Here is mine

Andrew,

does not look under real pressure. I have had some at hurricane force

We have 6 VM's running on there so all of the VHD's are on the SAN, 2x file servers 2x DC's, a print server also running WSUS (that uses SQL but it's not very heavy) and a Citrix box.

I was exporting a VM when that screen shot was taken so it might be under more load than normal.

It seems to be coping very well, they're impressive units

[Butuz]

Yep they are amazing units.

Currently I am running 3 x VM's on mine over NFS3 on a single Gigabit link. One terminal server serving 36 thin clients, and 2 low use web servers serving our sharepoint intranet, helpdesk and other random web based software. As linescanner says it is not even being tickled.

Will soon be adding another Temrinal Server, a SIMS server, and a couple more low use web servers onto there.

Over the next couple of months I hope to upgrade it with port trunking etc to give 3 (hopefully 4) gig links for each SAN and 2 (hopefully 3) gig links to each ESXi server.

I am sooooo glad i went a totally different way to everyone else around here and gave Sun a try (thanks to linescanner!!). I won't buy anything other than SUN now - no need.

I've currently got 3 NIC's in an LACP bond running the iSCSI traffic (might change that to NFS at some point) and one for management at the mo maybe CIFS soon. I was a bit sceptical at first but like I say it's running a few busy servers now and it seems to cope. Except when I’m exporting a Xenserver VM but I think that’s down to a Xenserver bug, I’m looking into that.

You know Grant you could turn off the charts you don't use so it just shows what you use like I have Will take a photo of mine tomorrow.

Our kids love encoding video straight over the LAN from it and it doesn't break a sweat doing that and the video encoding is fine.

This is an image of our 7110. We have 5 VMs and use CIFS for general shares - It is basically our whole admin network SIMS and all. It is only the disk that ever goes cloudy made me think that the caching drives might of solved that. Performance is great though I was pleased it only went as far as cloudy. I could of course (to make myself feel better) change the threshold settings to get all Sunshine - I might not know what's going on but at least it would look nice!

[cookie_monster]

My ops/sec look quite high compared but then it still only drops to slightly cloudy so i'm not going to panic

Here's how our S7410 looks this morning:



That's 400GB of staff and student resources, all the Year 7's userspaces and roaming profiles, all the mapped start menus (small files but extremely heavy use), and a couple of VMs. At present CIFS has one 1Gb NIC port and NFS has another, network has yet to be a bottleneck.

Don't forget things can go pretty far before you need to worry:



I had a laugh the other day - someone emailed me to let me know they'd just dumped a really big file on resources but it was only going to be there for a couple of days. It didn't bother me, but I thought I'd see if it showed up on the 7410 graphs:



(that's 94.3Mbps from pretty much one client on a 100Mb NIC)

Looking at the past couple of days, my highest figures are:

30497 CIFS IOPS
872Mbps NIC
14801 Disk IOPS
