Oracle DBs on a filer
by Jennifer Armenta 19 Mar '01

19 Mar '01

I was told recently from some who has worked with Netapp & Oracle implementations - it works real well for NON-transaction oriented databases. So things like Decision support, data warehouses, or reporting databases - it works well. In fact NetApp comes right out and says that they don't recommend using their box in OLTP configurations. The biggest reason is that OLTP database tend to be lots of little transactions and since you are using NFS (relatively big transactions) you won't get the performance gains as you would with a DSS config. Does anyone have experience with running Oracle with mass transactions that could help me (EMC vs' NetApps)

RE: Permanent Visible Drive Mapping From NT

Hi Martin: We use autoexec.nt in a large amount of installed servers, and have had no problems. You might want to make sure the AutoExNT service is starting as a Domain account that has access to the share on the filer. If you want, I could share some of our documentation/scripts with you. Cheers! -john -----Original Message----- From: Martin Hughes [mailto:Martin.Hughes@Halliburton.com] Sent: Friday, March 16, 2001 8:54 AM To: 'toasters(a)mathworks.com' Subject: Permanent Visible Drive Mapping From NT Good morning, all, I have a small problem (ignoring the larger and more visible ones). We would like to use our F840C as straight disk for some webservers. In order for the programs to register .dlls etc correctly, we need to have a permanent mapping on the machine for both the service account that we boot the machine on and anyone attaching to the machine through terminal server (ie like the C:\ or D:\ drives). We have tried using Autoexec.nt to create a batch file that runs 'net use etc etc' but when we do this the drive mapped is not visible to anyone logging in and you can remap the drive letter without getting an error/warning message. Is anyone else using the filer in the same manner and how did you get around this? We're thinking of using an NT group and forcing a drive mapping every time someone logs into it but this seems a bit heavy handed. All hints and tips gratefully appreciated.

SSH (Secure Admin)

I was wondering if anyone here is using the "Secure Admin" on the NetApp boxes ? If so, could you let me know if it is a "standard SSH server" that support scp also ? Thanks

HP-UX K-Class Gigabit Ethernet issues?
by Witham, John 15 Mar '01

15 Mar '01

Hi All: This may be slightly off subject, but we're migrating a large amount of data on an HP K580 (800GB) from an EMC Symmetrix 3930 to (2) F840s using Gigabit Ethernet. Initial Oracle testing is putting the 840 at 4x slower than the Sym we migrated from. We're 95% sure it's Gig-E related. We've been going through patch Hell, and I don't want to reinvent the wheel here. Is anyone on this list successfully using a K580 on HP-UX 11.0 with Gig-E? If so, can I PLEASE ask you to share your patch levels/parameter tweaks? TIA! John Witham Sr. Data Networking Engineer Takeda Pharmaceuticals North America, Inc.

Re: NFS version 4

Chris Thompson <cet1(a)cus.cam.ac.uk> writes: > Of course, we are probably still years away from usable client > implementations. I actually doubt that. There's enough interest in NFSv4 that it's likely to take off pretty quickly. Netapp has already done a preliminary implementation (according a paper I found somewhere, written by one of their engineers). Connectathon 2001 was just last weekend, but I don't know what the results of it were... http://www.connectathon.org/ As to RFC 3010, you'll note the work place of the authors? That might give some clue as to Netapp's plans. And anyway, it's still "standards track" which means it could still change. Darrell

RE: LTO support?
by glennm＠latticesemi.com 15 Mar '01

15 Mar '01

So judging from the two NetApp emails below, the company posistion on LTO drivers for NetApp customers is this: 1) We can't get a free drive to make drivers with, so we won't. 2) And NetApp is going to wait a long time (as much as "2 years") to worry about LTO as there is no market for it. The conclusion is that NetApp is to cheap to buy a drive and NetApp customers will have to buy LTO drives first before NetApp makes a driver (and there will have to be a lot of customers owning a drive before NetApp can justify making a driver). Well thanks NetApp! But times have changed! Get with it! In the past tape drives have been ahead of the curve for storage as a whole. But now with the big disk drives in huge arrays, the tape drive is way behind. So when a new drive like the LTO comes out, customers want (need?) to ramp up to the technology as soon as possible. And the OEM people like NetApp that supply drivers need to be aware of this. I, like many people, have a LTO drive now. And I am using it because I have a SUN driver for it. The driver was available when I bought the drive in January. On the other hand NetApp wants to wait? Why? To what advantage? The cost of a LTO drive is small change compared to your customer support issues. And waiting is only going to create problems between NetApp and it's customers. Help us please! Just my two cents worth. *************************************************************************** Glenn Marsh Lattice Semiconductor Corporation Unix Systems Administrator 5555 NE Moore Court CAD Engineering Hillsboro, Oregon 97124 glenn.marsh(a)latticesemi.com 503-268-8000 503-268-8136 phone - 503-268-8459 fax *************************************************************************** From: "Alvarado, Michael" <michael.alvarado(a)netapp.com> To: "'David A.

Please bear with me on this as I want to weed through the 'talk' and the 'hype' that jumps out at me in the below messages. Data protection and restorability is very serious business, not glamorous, not sexy, but pretty darn important if a company's business depends on it. Our goal here is to bring to our installed and new customer base a standard of 'proven' reliability in maintaining data integrity so that operations in workgroups-to-enterprise level environments go on as expected. With that in mind, field reliability and data to prove it out are top on the list of priorities for our certified solutions. Coming from a tape drive manufacturing area myself, I know that introduction (i.e. shipping vs. development and marketing) of a new tape format follows a fairly slow curve during the first two years before market/customer acceptance kicks in. LTO, as well as SDLT, will get there probably sooner due to both coming from the 'linear tape format' world and all manufacturers have a wealth of tape experience with other formats.

AW: LTO support?
by Poellmann, Christoph ISY 1 15 Mar '01

15 Mar '01

Hello, i am following the toaster's LTO thread with great interest. It came up just in time when we were about to order a library with LTO drives for NDMP based filer backup. We are not fixed to LTO, but we need and want the capacity and the performance it promises. This leads to the next question: Does or when will Netapp support SDLT drives?
