RE: Backup speeds across the network
by McCarthy, Tim 03 Nov '04

I saw a STK-9940B dump at 50+MB/sec via local FC and also 50+MB/sec via 3-way over gigE (standard frames). --tmac ====================== Tim McCarthy Professional Services/Systems Engineer NetApp Federal Systems, Inc. 410-551-3970 (o) 443-363-0208 (f) tmac(a)netapp.com tmac-pager(a)netapp.com ====================== -----Original Message----- From: Geoff Hardin [mailto:geoff.hardin@dalsemi.com] Sent: Tuesday, November 02, 2004 6:24 PM To: toasters Subject: Backup speeds across the network We have several filers and few tape drives so we are looking at doing 3-way NDMP backups.

Wouldn't the speed of the backup only be as fast as the slowest part of the backup environment? If you are using gige, you might want to check out jumbo frames and full flow control. Debbie -----Original Message----- From: Jerry [mailto:juanino@yahoo.com] Sent: Tuesday, November 02, 2004 3:59 PM To: Geoff Hardin; toasters Subject: Re: Backup speeds across the network It depends on your # and type of files. In some cases I get 13 MB/sec, but where I have lots of small files I get as little as 1.5 MB/sec. I am not bound by network at that time either. (This is on super dlt-3 drives, ~22 MB/sec theoretical i believe).

RE: User administration (was ssh scripts)
by Michael Christian 03 Nov '04

03 Nov '04

Yeah, I was looking into using expect, but turns out there is an easier way... The manpage for useradmin gives the following usage: useradmin useradd [ -c comments] login_name And when telneted or consoled into the filer, you get the same usage for useradmin: myfiler> useradmin usage: useradmin useradd [-c "comments"] login_name useradmin userdel login_name useradmin userlist [username list] *However*, if you do the same thing on a non-interactive ssh or rsh, the usage suddenly changes to something much more useable: > ssh myfiler useradmin usage: useradmin useradd [-c "comments"] login_name passwd useradmin userdel login_name useradmin userlist [username list] See, now that's much easier to script. -MikeC (Too lazy to use expect) -----Original Message----- From: Dirk Schmiedt [mailto:Dirk.Schmiedt@munich.netsurf.de] Sent: Tuesday, November 02, 2004 2:55 PM To: Michael Christian Cc: toasters(a)mathworks.com Subject: Re: User administration (was ssh scripts) Michael Christian wrote: > Next question.

Excerpt from http://expect.nist.gov/ : "Expect is a tool for automating interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, etc. Expect really makes this stuff trivial. Expect is also useful for testing these same applications. And by adding Tk, you can also wrap interactive applications in X11 GUIs." With the help of "expect" I wrote my own autoinstaller for filers named "NAAI" (NetApp AutoInstaller) who sets up our training machines every week. It's job is to wipe out all(!) tracks of the last week admin class. Connect to the Filers, "set-defaults" the BIOS, boot over TFTP, wipe out all data on the disks, step through the "setup" dialog, install licenses and ONTAP, set date and timezone, vol lang and options, and ... much more. ;-) => I really can recommend expect for automatisation of filer useradmin/password activities. Best regards! Dirk

RE: Backup speeds across the network

We currently have a Quantum/ATL library with built in NDMP tape drives (SDLT220) and are moving to a StorageTek library with Dinostor (http://www.dinostor.com) NDMP bridges and LTO1 drives. We use a separate gigabit network for backups, and see 20MB/s to the SDLT drives. A FAS960 can push 5-6 streams at 20MB/s. Even with a single stream, I haven't seen much above 20MB/s, so the drive seems to be the limiting factor in this case. Our old F760 used to be able to do 3 streams at 20MB/s, but would drop to 12-15MB/s if pushed to 4 streams. Dropping in a Dinostor in place of your tape host filer would take the load off that filer. What rates are you seeing?

I want to work with our DBA's to put our Oracle instances in Hot Standby to grab snapshots. Anybody got a script they use that utilizes SSH to run the snap command on a filer? Thanks -Rob

From : Mr Kingsley Tarawally. Address : Life Evangelical Mission Rue 11 Plateau, 18 bp 746 Abidjan 18 Abidjan, Cote d' Ivoire. Email kingsleywal(a)jumpy.it Hello Dear, It is my profound pleasure to write you regardless of the fact that we do not know in person, but your positive response towards my message shall be of great benefit to both of us, for the near future. I am Kingsley Tarawally, son of Chief K.S Tarawally, a Native of Mende district in the Eastern province of Sierra-Leone, who was the General Manager of Sierra-Leone Mining Co-operation (S.L.M.C) Freetown. During the war in my country, and following the indiscriminate looting of public and government properties by the rebel forces, the Sierra-Leone Mining Co-operation was one of the targets looted and destroyed. On this process, my father including some other top Government functionaries were attacked and killed by the rebels in November 2000 because of his relationship with the civilian government of Tejan Kabbah. This was a great tragedy as many top government Officials were victim of this attack. Being the only son of my father, I was left alone after my fathers death hence I lost my mother some years ago. My fathers relatives quickly decended on our properties immediately they came to know about my fathers death owing to the fact that I am single and have no good knowledge of all his properties. Unknown to them, my father told me some months ago before his death that he was planning for a business trip to Abidjan Cote where he secured some money for the establishment of a Private Mining Co-Operation. He told me that this money is the total of $10.5m He added that this money is contained inside a consignment and is secured in the Vault department of a Company in Abidjan Cote D'Ivoire. After my fathers death, while I was going through his file, I discovered a Deposit Document containing the information about this deposit and I quickly contacted the Company in Abidjan Cote D'Ivoire.The company have confirmed the deposit of this consignment by my father and also they show concern over his delay in clearing this consignment. I have just notified the Company of my fathers death since November 2000 and they have told me that this consignment can only be released to my fathers associate overseas hence my father secured this consignment to be released to him or his oversea associate. I am presently in Abidjan myself to monitor this matter and to make necessary contact for the release of this consignment. I therefore want your co-operation in this matter so that we can work together to retrieve this consignment from this company and then forward this money directly to your foreign bank account for joint investment. Contact me as soon as you receive this message so that I can give you more details and also instructions on how to contact the Company for the release of this consignment on your behalf as my fathers overseas associate.Please respond to me through the above email address. God bless you. Mr Kingsley Tarawally. Email kingsleywal(a)jumpy.it

You can change the password of a user created with the useradmin command using the passwd command on the filer.
