[opensuse] Usin hdparm as a Disk Performance Tool
by Greg Freemyer 23 Oct '08

23 Oct '08

All, Using hdparm as a benchmarking tool is fun, but it is NOT representative of most real life workloads, so don't get too focused on it. In normal use a disk drive does some read/write activity, then seeks to somewhere else, and repeat. DIsk seeks take real world time measured in milliseconds. Ignoring special cases that do large chunks of linear read / write activity, the biggest thing you can do to improve disk performance is to have multiple disk drives performing overlapped seeks. That is why people running data centers build raid arrays with lots of disks, that way they can have each of those disks simultaneously seeking around. Particularly when running a database, it is a huge win. IIRC, the formula that HP uses for designing these big storage systems doesn't even take per disk linear throughput into account. The variables are: 1) Raid type 2) Number of spindles 3) rotation rate 4) seeks per second Greg -- Greg Freemyer Litigation Triage Solutions Specialist http://www.linkedin.com/in/gregfreemyer First 99 Days Litigation White Paper - http://www.norcrossgroup.com/forms/whitepapers/99%20Days%20whitepaper.pdf The Norcross Group The Intersection of Evidence & Technology http://www.norcrossgroup.com -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] KDE time tracker?
by Ciro Iriarte 23 Oct '08

23 Oct '08

Is there any KDE based time tracker?, something like GnoTime (which couldn't find in the distro or any repository either). I would like to keep track of tasks as a freelancer, Project -> Task, time spent, etc...

[opensuse] how to check on drives behind an hp/compaq raid controller
by Per Jessen 23 Oct '08

23 Oct '08

A while ago, someone asked about how to monitor harddrives sat behind an HP or Compaq SMART array controller. I've been looking into it and whilst not as easy and straight forward as with smartmonctl, it does work pretty well. You need to get hold of a Proliant Support Pack from HP - these are freely available for download, but not necessarily so easy to find. Do some searching, and you'll find one. I used psp-8.11 for sles10. Another very useful tool is the nagios plugin found here: http://www.consol.de/opensource/nagios/check-hpasm/ With check_hpasm and the PSP installed, you can poll hardware status and get something like this: # /usr/libexec/check_hpasm -H localhost -v System :proliant dl380 Serial No. :8120FK411400 ROM version :P17 12/18/2002 cpu #0 is ok powersupply #1 is ok powersupply #2 is ok fan 1 speed is normal, pctmax is 50%, location is cpu, redundance is no, partner is N/A fan 2 speed is normal, pctmax is 50%, location is powersupply, redundance is no, partner is N/A 1 cpu temperature is 27 (58 max) 2 cpu temperature is 28 (68 max) 3 ioboard temperature is 26 (62 max) dimm module 1 @ cartridge 0 needs attention (n/a) dimm module 2 @ cartridge 0 needs attention (n/a) dimm module 3 @ cartridge 0 needs attention (n/a) dimm module 4 @ cartridge 0 needs attention (n/a) controller in slot 0 is ok controller cache in slot 0 is ok physical drive 0:0 is ok physical drive 0:1 is ok physical drive 0:2 is ok physical drive 0:3 is ok You can also configure the various HP daemons to generate snmp traps and/or send you an email when something changes. /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] How do I get it back?
by Jerry Houston 22 Oct '08

22 Oct '08

I clicked the red [X] next to my "My Computer" desktop icon (KDE 4), and it disappeared. I'm not sure what I was expecting - maybe just getting rid of the sidebar on the icon and allowing me to pack them closer together. But I think I'm going to miss "My Computer." Is there any way to get it back? I tried finding it among the available desktop widgets, but didn't see anything resembling it.
