We recently found out NetApp are not supporting 8.1 on the 3210 with Flash Cache installed

Hi,

I have seen the TSB regarding this. Do we also have a CSB? I have received several questions from my partners regarding this. Do we have a more formal answer to the remarks below from one of our Partners?

Hope you are well!  I believe you are in next week to see us but I wanted you to get the key information down in an email following on from what I briefly mentioned to you at Insight and hopefully we can discuss then…

As we recently found out NetApp are not supporting 8.1 on the 3210 with Flash Cache installed, this is going to be a major problem for us and when I discussed this with some of the senior engineers at Insight (can’t remember their names but hopefully you can) they suggested the only option is to replace the 3210 with a 3240.

As a solutions provider we offer RDRS to our customers and being unable to offer Volume SnapMirror when specifying potential deals and restricting the options we can offer isn’t acceptable.  When we purchased the 3210 for our Cloud offerings this was to replace the smaller 2020 models which we knew were not going to be supported/possible to upgrade to OnTap 8, to find that the investment we made into a 3210 to satisfy this requirement is now insufficient is very disappointing.  We need to be sure we are able to offer our customers the best possible solution, not the only solution available to us because NetApp do not support 8.1 on the controllers we purchased.

Compression is also a new feature I believe we would greatly benefit from, we have a lot of SQL backups create by customers on our hosted platform which are replicated to other data centres using SnapVault but we are restricted on the number of snapshots that can be kept since the SQL backup files are huge and create a large amount of changeable data.  If we can compress the SnapVault destination volumes then we will be able to keep significantly more backups on disk.

We would like to know what NetApp are advising customers who purchased the 3210 with Flash Cache should be doing in a situation where they need the features of 8.1.

Any ETA for fixing this (even vague)?

We are facing a problem with an existing FAS3140, happily running 7.3.x with Flash Cache, which needs to be upgraded at some point to 8.1.

The withdrawal of the support for Flash Cache in FAS3210 (running 8.1) makes me really worried, as this is basically the same issue.

Just talked to a Netapp SA today regarding this issue.  We have upgraded to 8.1RC1 from 7.3.x because we required the use of 64 bit aggregates on our 3140s.  At the same time we were getting flash cache gear only to hear about the warning bulletin.  Now I have some very expensive sheet metal underneath my desk.  Of course I'm reminded that for only a 6 digit fee I can be upgraded to the 3240s, thereby making the flash cache work.

In short the SA had no news.  There are some rumors that the fix may be in RC3, but they're only rumors.  It is not certain the fix will come in 8.1GA, if at all.

Philip

We don't have any 8.1 installs yet but have begun planning. 

It's all about card slots.  8.1 upgrades require a dedicated two port 10G-E card.  The card cant be used for any traffic other than HA/ontap stuff.  If you've got a flash cache card installed, you most likely dont have enough room for the card.

Simple as that, slots!

Re: We recently found out NetApp are not supporting 8.1 on the 3210 with Flash Cache installed

I don't think that is correct mjschneider.  This is a memory and software issue.  The 3210 and 3140 simply don't have enough memory to enable the flash cache.  We have 10G-E cards and still have plenty of room for flash cache, but installing it causes kernel panics on occasion.

Re: We recently found out NetApp are not supporting 8.1 on the 3210 with Flash Cache installed

I beg to differ.

The thing you are talking about is Cluster-Mode-specific & has nothing to do with the bug - see the description following the link provided above.

Re: We recently found out NetApp are not supporting 8.1 on the 3210 with Flash Cache installed

You're correct, I'm confusing 8.1 with what ever future version does away with the 7-mode/cluster-mode split...  We recently did some serious long term planning which is throwing me off.

Re: We recently found out NetApp are not supporting 8.1 on the 3210 with Flash Cache installed

Philip,

I'm in the same boat here.  We have a 3140 with PAM II / Flash Cache cards and have been told that we cannot run 8.1 either.  Our VAR and NetApp came up with a "solution" that involves replacing the 3140 with the 3240.  All we have to do is purchase it...   The release notes for 8.1RC3 still state that the 3210 and 3140 are not supported.  I had a meeting with my SE yesterday to discuss this problem and the only other option that came up was to get enough additional disk to handle the IO loss from removing the Flash Cache.

Not sure how helpful it is, but the just released 8.0.3RC1 brings the support for Flash Cache inside the FAS3140 (& FAS3210) back.

[edit] well, turns out, it isn't helpful at all
