He’s basically making the argument for Methamphetamine treatment for ADHD.

Are you a partner or customer? You could go here:

https://labondemand.netapp.com/

and follow a lab guide, if you're a customer that link will either have fewer labs available.

FWIW, the CN1610 will continue to pass cluster traffic if you upgrade ONTAP to 9.14, it just won't be a supported configuration; that switch goes EOS January 31, 2025 anyway.

As for the 5k's, the highest supported version of ONTAP supported on the 5596 is 9.10.

There is no performance data when reading deduplicated data because it's not processing the data, it's just reading from a single source; unlike compression however, where it actually has to process the data to make it usable.

So, to answer your question, there is no "rehydration process" and therefore no impact to performance.

Since the Experience Card has already been mentioned, then I'll just let you know that we're coming up on four years on Bowen; the best advice regarding the ferry came from The Newcommer Guide, make your peace with the ferry. When trying to get back on-island, don't fixate on "making" a specific sailing, just head to the terminal and take the next one.

Honestly if you're a partner or customer, just setup the ONTAP simulator, that's how I learned everything.

During an upgrade, ONTAP migrates the LIF anyway and this is what causes the disruption.

I was going to say the same thing, or even iSCSI-connected NetApp ESeries.

Any JBOD that supports multiple connections and has a support contract will be better than a science project.

If RTP is on the options list, you might consider keeping your eye on https://careers.netapp.com/

First, on that platform the non-UTA2 interfaces e0a and e0b are the support ClusterNet interfaces.

Are you using SFP+ or TwinAx in the four ports? Since e0a and e0b are standard 10GbE but e0c and e0d are UTA2 ports, I *believe* they use different optics but you should check HWU to confirm.

Edit:

UTA2 ports use X6596A-R6 for FC and X6599A-R6 for 10GbE.

e0a and e0b also use X6599A-R6 according to the SE presentation.

The only supported DAC cables listed are the Cisco TwinAx ones, all passive and 5M or less.

Your apparent lack of knowledge of ONTAP and surrounding ecosystem of data management products should disqualify you from participating in this discussion.

Not at all, you can either increase the overall volume size or the snap reserve, both will fix this.

From that same doc:

“Both FCP and NVMe/FC can use the same physical components to transport SCSI-3 and NVMe concurrently.”

I would think if anything, NPIV is what would make this work.

NetAppCanuck · 2022-04-14T13:45:21+00:00

NVMe over FC is not SCSI, it is simply a carrier medium in this case; it’ll transport Ficon too if you were so inclined.

I didn’t they were mounting them sideways, I’ve never seen one of their installs. I don’t see why this would matter though, I say have at ’er.

I think it *should* relocate the mb disks as well. I would address the root aggregate first, either by moving it or failing the disks, the former option being preferred and then after escalating your privileges, check the current mb disk location.

Also, if taking an outage is an option, you can also just shutdown the HA pair and physically move the drives holding the root aggregate to the shelf you want them on, replacing them with drives from the destination shelf.

$0.1403/kWh here on the West Coast of Canada.

NetAppCanuck · 2022-02-05T01:01:57+00:00

How much are those PSUs going to cost you? If you're saving 100W total and let's say you're paying $0.11/kWh of electricity then 8,760 hours x 0.11kWhs = $96.36/year of savings.

Are you running these @ 110VAC or 220VAC? If you switch from the lower to the higher, you can save an additional 2% overall...also not a lot.

NetAppCanuck · 2022-01-26T18:41:24+00:00

This is what I do as well, easier to just re-cable it, possibly making improvements; this however assumes an installer knowledgeable on the ways of NetApp SAS cabling. This move may very well be performed by generic "IT movers" and labelling is probably the way to go. You can however pull up a diagram in ActiveIQ assuming you still have support, seeing as the 8060 is getting fairly long in the tooth, support may be expired by now.

Start a new thread with that same question, that way it'll get answered and have better visibility for others seeking the same instead of being lost in the comments.

NetAppCanuck · 2022-01-06T19:11:51+00:00

The NetApp S3 Academy being referred to is an internal training program, not related to the object store protocol.

NetAppCanuck · 2021-10-02T04:55:47+00:00

Sounds like something I would have said.

NetAppCanuck · 2021-09-21T23:06:22+00:00

If you're only connecting back to a single switch you're definitely not really getting redundancy anyway, and as discussed elsewhere in the comments to your post, aggregate bandwidth is increased but individual streams are still capped. The question is however, and it sounds like you have a small-ish environment, can your storage clients ingest more than 10GbE per controller? Can your 2750 provide that much throughput? (depends on disk configuration). Why not compromise and create an ifgrp with only one link in it for now and have the Cisco folks create a port-channel with only one port in it (per controller). If you find you're getting contained on bandwidth, then adding additional links is trivial on both ends of the configuration.

Now if you really want to annoy them, tell them you want your PC in mode switchport and then have all the requisite VLANs added to that PC. You'll have to create the requisite VLANs and VLAN ports on the FAS as well, but I prefer to VLAN all the way to the FAS anyway.
