HP LTO
by Pramod S 23 Mar '02

23 Mar '02

Hi , I have an 880C running 6.1.1R2. I have an M1500 from Quantum with HP Ultrium LTO Drives. Since HP LTO is non-qualified, I have made an Entry in the /etc/cloned_tapes. But even after that, i still get an "non-qualified " when I run the sysconfig -t. If I do an mt -f <device> status, and then run the sysconfig -t command, it shows the devices correctly. But this lasts till I reboot the filer. After reboot I have to again do an mt -f <device> status, to see all the devices in sysconfig -t output. My /etc/cloned_tapes entry is HP Ultrium_1-SCSI EMULATES IBM ULTRIUM-TD1 Any suggestion on why this is happening?? Thanks, Pramod

RE: R100 Price?
by 張自光 23 Mar '02

23 Mar '02

After discuss with my manager, I found I misunderstand the market placement of the NearStore R100. And, the performance is very good and well worth the price. You are right, Joe. $0.03~0.02 per MB is too good to be true with the NearStore performance. Therefore, I hereby retract all my opinions and criticisms. Allen TK. Chang Syscape Tech. -----Original Message----- From: Joe Luchtenberg Sent: 2002/3/22 To: toasters(a)mathworks.com <mailto:toasters@mathworks.com> Cc: Subject: RE: R100 Price? No error. Note that this price is for 12TB raw (that's the cost to get into the NearStore dance). Well under $0.03 per raw MB (NetApp promotional materials cite $0.02, but I think that's just for the h/w - list price is $275K for the base 12TB system). That's a whole bunch less than a filer -- an F840c or F880c at 12TB will run you 2.5-3x more, and multiple smaller filers even more than that. Of course, the NearStore isn't meant to replace production filers. You're right to make the comparison to other nearline storage devices, and that's where NetApp has to sell its value proposition. I.e. integration with other filers (SnapMirror, SnapVault, SnapRestore), snapshot technology, no latency (compared to libraries w/ media pickers), universal access, better reliability, etc... Other disk-based nearline products are rushing to market now, too. Some are simply repackaged low-end NAS being repositioned to grab some market share. Others may be real players. However, I don't think there's another vendor going this aggressively into the nearline market space that has the comprehensive solution and integration across the enterprise that you can get with NetApp, though. Of course I'm a little biased, since I make some of my living selling these things. :-] Joe Joe Luchtenberg Dataline, Inc.

Just for interest: http://www.nexsan.com/products/products/ataboy2/ataboy2.html I was quoted ~20K USD before discounts for a full 1.6TB 3U shelf. Given the 12TB starting point, the head and software and incremental discount as you get bigger/more of them I'd say the R100 is fairly decent value. The opening markedroid babble made me think it was an HSM product which I've hoped NetApp would consider doing for a long time. Sadly it's just a backup staging area that could make a decent high-capacity straightforward filer for many people. Nice start into a developing storage niche though. -- -Mark ... an Englishman in London ...

RE: Migrating NT directories...

Check out Quest Software's Fastlane DM Consolidator. Excellent tool that migrates local users, groups, file permissions, and changes SIDS. http://www.quest.com/fastlane/consolidator/ <http://www.quest.com/fastlane/consolidator/> Used successfully on several NT file server migrations. Very quick, too. If you're using just global NT groups for security and don't have to recreate local groups and users, a simple backup and restore preserving file permissions would work as well. Assuming your backup software preserves the NT ACLs (some don't), and the filer volume uses NT style permissions as well. -warren Warren Walsh Honeywell Laboratories Information Technology 612-951-7837 warren.walsh(a)honeywell.com -----Original Message----- From: Don.Hickey(a)alcatel.com [mailto:Don.Hickey@alcatel.com] Sent: Friday, March 22, 2002 8:08 AM To: toasters(a)mathworks.com Subject: Migrating NT directories...

Take a look at RoboCopy from the NT resoucre Kit. I havn't tried in on the filer but I would think it would work.

RE: Simple 760 question ...

That's correct. You can not add RAM to any of NetApps Filers. They are configed and shipped from the factory and cannot be modified. Only way to add RAM would be to upgrade the head. -----Original Message----- From: Rune Bakken To: 'toasters(a)mathworks.com' Sent: 3/22/2002 8:58 AM Subject: Re: Simple 760 question ...

RE: Putting a DS14 in a clustered system with mixed shelves ...

Same thing. I've done several of these. Even in a clustered config, the Filers are still autonomous until a fail over occurs. So, when adding a DS14 to an existing loop, it needs to be the last one on the loop. You have to break the cluster. Down the filer your adding the shelf to. Ad the shelf. Bring filer back on line. Re-establish the cluster. Good luck.
