RE: F85 - EMC IP4700
by Berke_Mitch＠emc.com 30 Apr '01

30 Apr '01

Has anybody had any experience with the F85? I'm most interested in the hardware. As a continuation of my last message, EMC is pushing hard with an IP4700 against an F85. They've been touting the reliability of their box and that it has no single point of failure (2 processors, etc). .... Also, does anyone know what type of failover the IP4700 is actually providing between their 2 storage processors. ----------There is a direct/point to point Fibre channel link between the service processors. These service processors are in an active/active failover configuration. It doesn't look at first glance that the surviving processor takes over the MAC address of the dead processor. It just starts arping for the IP address of its partner. ----------If there is a network connectivity failure of any kind, caused by a dead switch port, bad or loose cable, bad NIC etc., the surviving Ethernet interface on the IP4700 issues an ARP to the LAN switch to update its ARP table so all traffic destined for the dead MAC address is redirected to MAC address of that surviving Ethernet interface. At this point the remaining LAN interface sends & receives LAN traffic on behalf of the failed NIC, but the data serving is still executed by the Service Processor that is still alive behind the failed NIC. We can accomplish this by sending the data over the previously mentioned Fibre channel link that resides between the 2 service processors. After the IO request is processed, it is sent back across the FC link & out the surviving LAN interface.

Yes, when using Netapp DUMP and RESTORE, via telnet/console or rsh, all CIFS/NT attributes are maintained.

I seem to remember it reading all the way to the end of the tape Neil, but I may be wrong. Veritas Netbackup seems to do this too.

Re: How would you respond to this -Reply

Maybe I'm missing out on the really important aspect of netapps??? Other than a jacket I got at Admin training I've never received my new clothing line from Netapp! Is this an optional part of the Support Agreement, or should I start complaining that I'm not receiving the level of support from Netapp that I should be! For the benefit of you netapp guys who monitor this board, I wear an Extra Large. Of course, in Netapps defense, I've never received any EMC shirts either. (p.s. don't bother with the boxer shorts, I won't wear them) >>> Chris Lamb <skeezics(a)measurecast.com> 04/19/01 07:00pm >>> My story about EMC is rather different, I guess. Some local EMC reps scheduled a visit with my boss and came to visit us a while back. I wore not one but _two_ NetApp shirts that day - the very cool engineering shirt (black pre-F630 shirt with Mothra on the back) and the snazzy denim Land's End shirt with the embroidered logo on it. The night before I printed a copy of the recent INPUT survey, highlighting the part where I'm quoted (anonymously), and left it on my boss's chair. He brought it to the meeting. They arrived. I smiled and shook hands and did the business card thing. We sat down at the conference table. They asked their questions, and I politely answered them. It went something like this: "What about reliability?" they asked. "I've been running NetApps since 1995, and to the best of my recollection I have never once lost data due to hardware or software failure," I replied. "Yes, but what about uptime?" they inquired. "alexandria> uptime 3:32pm up 187 days, 14:10 1162740653 NFS ops, 129052586 CIFS ops, 0 HTTP ops colossus> uptime 3:32pm up 171 days, 8:48 1692312427 NFS ops, 0 CIFS ops, 0 HTTP ops", was my reply. "Expandability?" they suggested. "I have 21 free slots for more disks - I bought the box with extra shelves and a 2nd controller so that I could grow it on-line without any need for downtime. I can grow our box to > 1TB without even thinking hard." "Performance!" they pleaded. "My Oracle DBA is happy, and says he can't see a difference between the 760 and a locally-attached dual-loop A5200. Besides, with a head-swap we can trade up to the 800-series, or cluster, or trade-up and then cluster, and I've got all the slots I need to add extra Gigabit cards..." "Yes, but our 'phone home' support feature and customer service are second to none!" they intoned. "Actually," I said, "your story about the hardware tech showing up on a Saturday with a replacement disk for a demo machine reminds me of a similar incident... one day a box arrived unexpectedly from Netapp with a replacement drive in it, which puzzled us because we hadn't reported a failure. But sure enough, we walked into the server room and one of the disk canisters had a red light on. Five minutes later we swapped it out and that was that. Sure a lot cheaper than sending a field circus guy out to do a job that any basic systems operator can do." (Ouch, that stung a bit, but hey, I _like_ playing with the hardware, and if I have one complaint about the reliability of my filers it's that after I bolt it into the rack and plug it in, I don't get to fool around with it much. That's a blessing, of course. :-) "And as for service, a funny thing happened in the middle of the night a few months back, when I was innocently rearranging some power cords to balance the load on a split-phase UPS, oblivious to the fact that the 'autosupport' emails were being sent out. Imagine my surprise when an email arrived 20 minutes later from the Netherlands, asking if I needed to have a replacement power supply shipped..." They got the point. Clearly, they weren't going to make a sale that day. :-) But we listened to their presentation, and had a pleasant enough chat, and that was that. I had done my homework about their product line, too, and I think they knew it. They didn't try to BS me, and they didn't try to badmouth Netapp. So I can't comment on whether or not this is typical behavior from EMC reps, but my experience wasn't at all negative. Mostly, though, it's the shirts. If my vendors didn't clothe me I'd have nothing to wear! :-) -- Chris (still waiting for NetApp boxer shorts) -- Chris Lamb, Unix Guy MeasureCast, Inc. 503-241-1469 x247 <skeezics(a)measurecast.com>

alternate shelves/disks for F330?
by Bill Bradford 30 Apr '01

30 Apr '01

Looks like 2 and 4G storageworks cannisters are going to run at least $100 each, and heck, I only paid $150 for the F330.. 8-( I know its unsupported as hell, but since this is standard SE narrow SCSI, would it work if I just slapped a Sun disk multipack on the filer? I'm just trying to get this up and working at home, as cheaply as possible... Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

If the data on the filer has NTFS ACLs, you'll need to backup over CIFS or a use a package that supports NDMP. If you back up over NFS, you'll loose any NTFS ACLs and as well as any DOS file attributes. If you backup over CIFS, you'll not only retain the ACLs and the DOS bits, you'll retain the UNIX file permissions as well. Plus Data ONTAP keeps an archive bit (DOS) on UNIX files so that you can do "incremental" backups of UNIX data.

More case stuff
by Jan Chrillesen 29 Apr '01

29 Apr '01

Reading through the last couple of weeks posts about the case surveys and how much NetApp appreciates feedback I realised that there's a few things about the case handling that could use some improvement. The "Receive email notification on status change" feature is nice, but being a regular user of Cisco's CCO I miss the following features: * Being able to add adresses to CC on case updates * When I get a mail about the an update, it's just a link to the case. It would be great if the mail included the text that was added to the case. Some way to force a core dump (halt -d) without opening a new case. I've tried stuff like (halt -d forced-dump-for-case-123456), but new cases is opened anyway. A "magic" string to pass to -d would be fine. Sometimes I turn off autosupport before dumping a core, but that's also a bit annoying. Finally, why can't I close a case? Sometimes engineers seems to forget about cases and they stay open forever, even after I ask the engineer to close the case. I know I can close a case, when the problem is considered to be solved, but with a forgotten case this is not possible. 179738 is such a case, in case someone within NetApp would bother closing it. /jan
