Dear Sir/Ma, I am Aderele Sijuade 18 years old boy from Nigeria. I have finished my senior secondary school (SSS), here in Nigeria in the Year 2002, which I have 5credits in my papers. After that I went for Computer Training and I did Diploma in Desktop Publishing. Then I heard about Test Of English As Foreign Language (TOEFL), which through it someone can further his/her education in abroad and which I was interesting in doing. I wanted to study AEURONAUTIC Engineering, which the course is not offer in the Universities here in Nigeria and even strike every time which slowdown one study. Im really interested in doing this course not only for my own good also for the people around me to gain from the knowledge that I will achieve and also for my future exposure. I will be grateful if you can assist me financially so that I can obtain the form and take the examination. I will work when I get there to pay for my school fees and for any other thing that I need to pay for. Thanks. Yours Faithfully, Aderele Sijuade. ________________________________________________________________ The best thing to hit the internet in years - NetZero HiSpeed!

URGENT NEED. I am Henry Winndu, an Aide of Ex President Charles Taylor. As you may know he has recently stepped down from power and is presently in asylum in Calabar. The purpose of my letter is to ask if you can render the assistance requested and to bring to bear my present position and the very need for true and solicited help with respect to Ex President Taylor. Your assistance is needed in the sense that some funds derived from Diamond sales during his tenure needs to be transferred/moved from its present location to a place or an account that you may hopefully provide or arrange. The reason for this is that plans are underway to confiscate not only his known fixed assets but also liquid assets. I have been mandated to seek and find a relaible person, based overseas, that is disposed in helping to secure some or all of the funds in question. if this proposal fascinate you, and you are willing to assit kindly e-mail me. Otherwise no offence meant. Sincerely yours, Henri Winndu. Alternative email: henriwinndu(a)123.com Please provide your telephone for immediate contact

RE: slow dumps
by Rogers, Jamie 17 Nov '03

17 Nov '03

I wanted to relay some the information that I received regarding my problem with slow file system dumps from my toaster to my Solaris 8 remote tape. As well as thank those persons who responded. I received three suggestions. The first was to try using a different blocking factor, I had tried using different blocking factors but not larger as in this suggestion. I am evaluating a blocking factor of 128 which has doubled my throughput. Not what it should be but still a 100% improvement! As has been noted you have to keep this in mind on a restore as well. (rsh $FILER dump 0ubf 128 $SUNBOX:/dev/rmt/1 /vol/vol2). The second suggestion that I received indicated a similar issue with a very wide but not necessarily deep directory structure where NDMP dumps went from 50+GB/hour to around 8kbps. Apparently "NetApp have indicated it is an NDMP/dump issue and there is no fix". However this site upgraded to 6.4.x and saw much greater throughput, (no data). I have not yet decided to upgrade Data ONTAP. The third suggestion that I received noted that "Lots of small files, especially lots of small files in a single directory is a dump performance killer. Basically you spend a lot of time doing the meta data stuff (path, permissions, etc) and little time to get the tape streaming to dump the data. I'd be willing to bet the same amount of data but in a few large files would back up significantly quicker...at least that's been my experience." This is indeed true. He had two suggestions. The first was to try using the native hidden command "dd" on the filer which is really less friendly than the dump command but might be worth a try. "DD" has its draw backs and limitations and it seems like it might be an administrative nightmare. The second suggestion was to use snapmirror, which is unfortunately a bit cost prohibitive. Thanks for all your help. I'll let you know if an OS upgrade helps if I try it. Other suggestions are always welcomed. -Jamie -----Original Message----- From: Rogers, Jamie [mailto:jrogers@aware.com] Sent: Tuesday, November 11, 2003 4:10 PM To: 'toasters(a)mathworks.com' Subject: slow dumps Toasters, I have an F760 running data ontap 6.3.1 with 4 FC-9 (7x32) shelves attached. I use Ultra 10 with a HP SureStore718 LVD autoloader for remote backups. I use rsh (rsh filer dump 0uf sunbox:/dev/rmt/1 /vol/vol1) via a cron job to run the dump. The Ultra10 and the filer are connected on a private network via 100TX crossover cable. Local file system backups (from the Ultra 10) to this tape drive go at about 4+ Meg/sec, great. The root volume of my filer and /vol3 dump at 4+ Megs/sec, this is great. However 2 volumes, vol1 and vol2, dump at 571Kb/sec. This performance is independent of the interface used, I get the same results using my 100TX or my gigabit. Likewise I get the same results when the dump is run from the filer, that is eliminating rsh. Sysstat looks normal during both dumps. The only difference in the volumes is the number of files, volumes 1 and 2 each have about 2 million files where as volume 3 has 1.2 million files and the root is about 10,000 files with out quotas. The data on volumes 1 and 2 consists of lots of small files and changes frequently whereas volumes 0 and 3 are pretty static. I have already cut the volumes up into 4 qtrees of 30G each. A quota report does not look out of the ordinary and no single quota tree has more than 950,000 files, see quota report below. What could be causing the dumps to progress so slowly?

FAS200 series performance
by Geoff Hardin 12 Nov '03

12 Nov '03

Has anyone seen any performance numbers for the FAS200 series? We are looking at upgrading / replacing some older F700 systems and I wanted to know how they stacked up. I know the disk capacity isn't all that much different (4 TB raw for FAS270C vs 6 TB raw for F760C), but what about NFS ops? We're not pushing that much through now, but if we start consolidating... -- Geoff Hardin geoff.hardin(a)dalsemi.com If you want to get to the top, be prepared to kiss a lot the bottom. - Despair, Inc.
