Third Party FastEther for Filers
by Ben Rockwood 20 May '04

20 May '04

Howde Toasters. I need to use VIFs on a F700 for awhile but the network doesn't have GigE capability and all my filers are built out with dual Gigs. So I need to find a cheap FastEther PCI card that I can use together with the onboard FastEther for VIFs for awhile. Does anyone know what 3rd party options I can use? I'm hoping that something commonly availble (Intel FastEthers, or something) so that I can just hop by Fry's and be done with it and not have to involve a reseller. Anyone done this? benr.

URGENT ASSISTANT

PLEASE ASSIST THE NEEDY I want to crave your indulgence in reading through this mail to understand my predicament.I am Prince johnson, a Liberia refugee currently residing at the refugee camp here in Accra-Ghana and I am 26 years old. All hope of having a better future was shattered by the war in Liberia because I and my aged mother being the only surviving family of the slain Minister of Mineral Resources of the defunct government of LIBERIA were left with no alternative than to flee to Ghana. Please I am contacting you today for you to extend a hand of fellowship to poor victims of circumstance. I want you to consider affecting my life and that of my aged mother. All hopes was lost until recently when my late father Attorney visited the refugee camp andI was fortunate to meet him. He had come searching for us at the camp to pass on certain information that will affect our existence. He said my late father had deposited Eight million united state dollars ($8m) in a trunk of boxes/ gold and diamond with a Security Company here in Ghana since June 18th 1997 stating me as the Beneficiary in event of his death.Considering his relationship with my late father, he has since handed these documents to me and I have equally gone to verify these claims hence I am contacting you to assist me in retrieving these consignments. Please, what I actually want from you now is to assist me in retrieving and receiving these consignments on my behalf because I cannot handle this as a result of my current situation. I have not disclosed this to anyone before contacting you hence I want you to kindly keep this as confidential.I beg you in the name of God not to underestimate my claimsand request because I shall endeavor to furni sh you with the necessary documents.Please be kind enough to send me an email cos for now i dont have a phone. Thank you very much and God shall increase you and your family more abundantly. Regards Prince johnson(for the entire family)

I must apologise for being half-asleep and therefor overlooked the significance of the request ;-). Pse note, the following are real results obtained while testing with a representative mix of user data. There were a few restrictions at the time: I was only able to use a single FC port on an F880 and the 4 LTO 1 tape drives were attached to two FC-SCSI routers. Networker 6.1.3, Ontap 6.3. Administration = History Backup Data Including Excluding Operations Volume Administration Administration MB/sec GB/Hr MB/sec GB/hr 1 122 22,3 80 25,1 90 2 244 38,4 138 47,3 170 3 366 51,7 186 63,5 229 4 488 59,8 215 77,5 279 The following assumption was made based on backup and recover tests: backup +- 50 GB/Hr, recovery +- 25GB/Hr Operations Backup Recovery Estimated Measured Estimated Measured GByte/Hr GByte/Hr GByte/Hr GByte/Hr 1 50 80 25 62 2 100 138 50 120 3 150 186 75 144 4 200 215 100 160 Btw. I just remembered, the Networker server was a PC with a 200 Mhz Pentium, 128 Mbyte RAM.

I have four older F760Cs that are getting about 5-6 MB/s to local tape drives. The problem is that I also have another nine filers (1 F630, 1 F720, 1 F740, 6 F760C) that are backing up via 3-way NDMP and we are lucky to see 4-5 MB/s; most are in the 1-2 MB/s range. And don't even get me started on the Solaris/SunOS/Linux/HP-UX/DEC clients that backup through the drives attached to the filers (0.1 - 2 MB/s). We were looking at upgrading the tape drives and such, but we have done a few test dumps from filer to filer, filer to LTO-2, and filer to LTO-2 attached to a Sun, and the numbers didn't improve much (definitely not enough to justify buying a new tape library / tape technology). Just a little background: We are using DLT7000 tape drives, which should have a maximum through put of about 10 MB/s (2:1 compression), contained in a Quantum P3000 library. We have all our filers on two separate networks; one for general data sharing and a private one for our backups. The private network is all GbE (fibre) using the Alteon GbE cards (Gigabit Ethernet Controller II). We are doing qtree dumps, and while some of the filers have only four qtrees per volume, others have over 40. Each qtree is generally capped at 200 GB max, and for those filers that have lots of qtrees, we still try to limit each saveset to around 200 GB. So, I guess what I'm really asking is 1) "What kind of speeds are you seeing?" and 2) "Am I doing something wrong?" Many thanks, Geoff Hardin geoff.hardin(a)dalsemi.com Difficulty is the excuse history never accepts.

We get about 20MB/s to GigE SDLT drives. The drives have a built in NDMP server and are on a private GigE network with the filers. Our FAS960s can push 6+ streams at 20MB/s each, the F880 maxes out at about 5-6 streams. Our F760 used to manage 4 streams at 15+MB/s. We are switching over to LTO drives connected to DinoStor Tape Servers (http://www.dinostor.com) which do the same job as the built in NDMP server that our SDLT drives have. In our experience, and that of our NetApp SE, direct attached tape drives have worse performance then network attached drives. NetApps are optimized for sending data out of the network, not for dealing with tape drives. John

HP Omniback/Data Protector with NDMP integration option
by Derek Lai 18 May '04

18 May '04

Anyone else using HP Omniback to backup your filer? I inherited a FAS940 cluster and HP Omniback 4.10 environment. We are currently using a PC as a NTFS gateway to backup CIFS shares on NetApp. The performance is pretty poor and we are having all kinds of problems. I wanted to upgrade to the latest version which HP has renamed DataProtector 5.1. I also wanted to use NDMP to backup the CIFS shares. This is suppose to be free for us. I was told that the previous administrator had tried NDMP integration with Omniback for some time and then abandoned it. No one seems to know the reason though. Just wanted to get a feel for what experience others with similar environment have had. Thanks. Derek
