Any experience...
by Robert Mance 01 May '01

01 May '01

with a company called Winchester Systems? They're advertising the 'World's Fastest RAID Disk Array' at a very reasonable price. I'm getting pressure from the CTO to get these things in here for eval. We currently have an F840 that I'm extremely happy with. I don't necessarily want to compare the two ... since the F840 is a NAS and Winchester makes locally attached scsi stuff. Just interested any any experience with the company and/or their product.

Backup solutions for NDMP with F740's
by Eric Hester 01 May '01

01 May '01

We have been using an ADIC Scalar 218 for some time with our F740 cluster with fairly good results until recently. Our Netapps provide the storage for our Web and Mail clusters. We have experienced pretty serious growth and are seeing some significant slow downs in backup turnaround time. We have up until this point also just been backing up the data over NFS mounts to our NetBackup server. Being that most of the data comes from the mail server side and we use maildir, it is not a huge amount of data but is a huge number of smaller files. I'm not very confident that NDMP would completely correct the problem, but it seems that removing the network/nfs overhead couldn't hurt. I think I have made the decision to go with the ADIC Scalar 1000 with 2 drives dedicated to the Netapps (1 to each in the cluster) with NDMP and 4 more drives dedicated to the backup server for other systems. 2 questions: 1) What are some impressions on NDMP as a performance gain for backups? Right now the network does not seem to bottleneck the process as we have dedicated 100m links from the servers to a separate NFS/backup network, and 4 channel etherchannel from each netapp to that same network. From MRTG graphs this network is mostly idle (10-20m max) even during backups. I don't appear to be able to keep the DLT's saturated (in other words the activity light doesn't stay on the whole time, so it is not streaming non stop) during backups, and I don't know if this is NFS overhead, or there is another problem. Is NDMP more capable of keeping a DLT fully saturated and therefore more efficient, or do I still need to look at this as a Netbackup issue? 2) A little OT but - Does anyone have any good experience with this particular library (ADIC Scalar 1000)? I loved our smaller Scalar.. but have more long term experience with StorageTek. My salesperson has done a good job convincing me of the advantages of this box, and I am pretty much sold. Just curious if anyone else has any horror stories or glowing recommendations. Eric Hester Director of Systems Engineering NuVox Communications eric(a)nuvox.net

RE: F85
by Tom "Mad Dog" Yergeau 01 May '01

01 May '01

The F85 and the IP4700 are NOT in the same class of equipment. F85 is for a small office, IP4700 is for a decent sized department (couple hundred users). If the F85 is what you need, the IP4700 is a total overkill. If the IP4700 is in the class you need, you should be looking at an F740 or F760 cluster, not an 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.

Also, does anyone know what type of failover the IP4700 is actually providing between their 2 storage processors. 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. barry

What do you mean by trust ? You can use QuickSetup software to setup a 6.1 and up filer into a Win2K domain in a safe way.

While I don't disagree with Tom, he doesn't mention that F85 can do many of the tricks that currently reside in the wish lists of others. For example: SnapRestore: near-instant full volume restore (the trad option is lengthy tape restore) without affecting other volumes on the same filer. No point having snaps if you can't get the data back. SnapMirror: asynch mirroring over any distance. This is done volume-volume so you can mirror a bunch of geo-dispersed F85s to something larger at HQ. Etc, etc, etc. The key to F85 is that, with the main exception of Cluster Failover, it can perform just about all the tricks of it's larger data centre siblings. I believe that NetApp are unique in offering this downward scalability (i.e. that a smaller solution shouldn't be penalised in the functionality department). Naturally, if your environment grows, you don't have to re-engineer your processes, just plug in a bigger filer. If you want head-redundancy, think F740C which, like the IP4700, won't fit under your desk. :-) Cheers, CAW Charlie Whitfield NetApp UK FBI voice: +44 20 8756 6762 mobile: +44 7718 160954 email: caw(a)netapp.com Repel the bozo invasion! -----Original Message----- From: Tom "Mad Dog" Yergeau [mailto:MadDog@fool.com] Sent: 30 April 2001 19:45 To: 'Barry Lustig'; Toasters Subject: RE: F85 The F85 and the IP4700 are NOT in the same class of equipment.

RE: F85 - EMC IP4700

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.
