Cisco, Microwaves and Virtualisation
So I’ve not posted in October so far and the month is half over. To my defence I spent a week in South Africa doing an equipment (Cisco) installation. No it wasn’t a holiday but I did see the fantastic table mountain, which is spectacular and well worth a visit.
Part of the installation...

- @alextangent OK, that clarifies the random I/O comment - thanks
- @alextangent OK, makes sense. So only impact would be if I/O so great, NVRAM gets flushed continuously.
- @alextangent <-- the same set of pages on the host (say 4K/8K). I can't see that being efficient as WAFL more suited to seq write.
- @alextangent I understand the architecture (done all the training), what I'm not sure is the impact on WAFL/NVRAM of high I/O to -->
- @Storagezilla @storagebod Let's do a trip to Cork! Get the undertakers to collect us and organise a massive fry-up brekkie!
- @alextangent I mean if I write to disk, am I required to destage an entire raid stripe to write a single 4K block or just that block?
- @alextangent OK, simple question. Can Data ONTAP accept a write and commit to disk a *single* 4K random block asynchronously?
- @Storagezilla The fun of camping out at LHR.
- @Storagezilla Don't tell me you're in London tomorrow....
- @alextangent depends on whether your underlying architecture is designed to handle full random I/O or not. If not, SAN isn't best choice
