RE: CPU Stats on multi-proc filers
by Hill, Aaron 14 Mar '06

14 Mar '06

Same issue with DFM for years and we have never come across a fix. We use sysstat -m as NetApp suggests when "zooming in" for closer analysis.

Which MRTG are you using? I've found that querying SNMP for the CPU busy (.1.3.6.1.4.1.789.1.2.1.2) use will indeed graph the AVG CPU, which is the sane one. I've never understood why most NetApp tools (all the way down to regular sysstat (except for -m)) report the ANY value. Davin.

RE: Block access (iSCSI etc)
by Glenn Walker 14 Mar '06

Having worked for NetApp supporting Exchange\iSCSI\FCP, and as a customer using NetApp\iSCSI storage for a rather large Exchange infrastructure, I have nothing but good things to say... it works and works very well. There are some things that FCP does better: - Speed 2Gb/s vs. iSCSI @ 1Gb/s - Resiliency MPIO on FCP has been around longer than MPIO on iSCSI - Track Record It's very old technology by comparison - iSCSI is still relatively new However: iSCSI will likely get a huge boost in speed once 10Gb/s networking hits with full force compared to FCP's next jump to only 4Gb/s. iSCSI costs way less to implement than FCP due to use of generic\commodity equipment (ie, off the shelf Gig-E switches\NICs\Cables) vs. FCP's specialized\expensive gear (ever price a McData or Brocade switch??). I am somewhat biased in my opinion - I know that NetApp makes very good HW\SW and has excellent support... I can't speak to the other vendors out there because I frankly don't know them all that well.

RE: Just a spam resource now...
by Ferrett, Simon 14 Mar '06

I'd think that moderating new subscribers until they've made a couple of salient on-topic posts that indicate they're not spam-machines would probably go a long way to addressing the issue. I'm not sure if the list owner, or anyone, has time to do that (or what the rate of new subscribers is) though... Simon.
