Important: Data ONTAP 5.0 requires 128MB of memory on the filer to run properly. If you do not currently have 128MB of memory, contact our Installed Base Group either by e-mail or by phone at 1-888-2NETAPP.
Ouch. 128MB? Why is that? Will filers be sold with a minimum configuration of 128MB in the future?

This is a combinations new features and better testing.
Better testing? Well, we've discovered some rare but real situations where low memory can cause deadlocks or panics. We did change some algorithms, but it also seemed sensible to increase the memory requirement. We checked our manufacturing database, and we believe that of the four-thousand-plus filers in the field, fewer than 100 currently have less than 128 MB of memory.

So now we are being 'forced' to buy another 64MB...if we wanna continue to upgrade.
(yep - we are one of those < 100 people with a small filer and 64MB)
Well, not to be too critical of somebody's situation, but given that the netapp is already a relatively pricey solution, I would guess that anybody that scraped the bucks to buy one, can swing a few hundred more for 64MB's.
We bought ours from Kingston, works just fine.
Anybody actually running gigabit ethernet on their filer? I'm thinking about it...
Too bad you can't use the filer as both a filer and low end netcache.

I elped a friend of mine get it working. The alttune command under rc_toggle_basic is your friend (if you are using a non-alteon switch). Turn off link auto-negotiation.
My friend is using a Prominet (now Lucent) P550 switch. He is very happy with it. I am scheduled to have a loaner box from them and will buy it after (should it work).

Well, I am...sort of... I have a loaded memory F330 along with a Sparc 5. I have *all* my data on my F330, and I am running the Netcache software for Solaris using a *private* 100BaseT network with the Filer. Works great! PC's have access to home dir's via CIFS, UN*X machines can access via NFS, and NetCache running over an NFS mount on the F330. (granted I only have a 2 B-Channel ISDN, but it makes the Cache look REAL GOOD!)

I, too, have only 64MB of RAM, and have never seen any memory shortage. I find it hard to believe that an OS upgrade would suddenly require so much more memory. grrrr.

The major reason we upped the memory requirements for 5.0 was for some edge conditions where many disk blocks were being dirtied at once. This happens mostly for deletes and resizes of very large files. Previously this would lead to deadlocks in the OS.
In 5.0 we've made fixes that work around many deadlock situations. Part of the fix involved increasing the reserve of free memory available for wafl to continue to make progress.
New features such as improved checksum computation offloading for Gigabit Ethernet and Multiple Raid Groups and Volumes also needed more memory.
So although we're now using more memory, the tradeoff is that the filer should be even more stable than before and support all the new features in 5.0.

David,
That's a valid comment, to be sure.
I spent 8 years at Sun and 3 years at Cisco and requiring more memory to run new versions of SunOS (later Solaris) and Cisco's IOS, was an ongoing issue, and no doubt still is.
Every manufacturer aims to keep the required memory as low as possible but has to balance this with the demands for new features customers want.
At least Net App's OS requires a lot less memory and disk space than NT (which is now 27MB in size, I'm told), UNIX, or Cisco's IOS.... I saw a recent oil company example which showed a Filer leaving 200GB of usable disk space from 25 x 9GB drives. The UNIX equivalent was 160GB of usable disk space from the same 25 x 9GB. Net App does give you low overheads, as a result of its purpose-built architecture.
A Filer is generically much more like a router than a general purpose Unix or NT box, but we still require much less space than Cisco's IOS, for example.

Excuse me? You require less memory than IOS? Did I suddently reappear in another universe where IOS requires 128mb to run? :-p
You can even run a couple of full BGP views in a Cisco with 64mb -- and that's to compensate for Cisco's braindead table archietecture.
