BlueARC SI7500 NAS
by Dilbert Dickweed 22 May '01

22 May '01

Obviously nobody here has really touched one from the statements made. I have and have done direct compare between IP4700 (EMC) and 840 as well as the BlueArc box and it is very refreshing. It is true that some of the feature set is not there yet but they do have NDMP and unlike Netcrap, back-ups online don't crash the server. I have done my own IOmeter tests with various settings using some FreeBSD clients and this thing blows away 840 and IP4700. IP4700 is a joke anyway. Those who are in doubt (as I was) need to check these guys out because they are really onto something huge here. We are talking about eliminating the bottlenecks that exist in ALL server architecture today and reaching the next level of speed. I am not talking out-my-ass here...check 'em out! See for yourslef and don't listen to the dinks from Netcrap or Evil Machine Corporation EMC! If you do manage to get a beta unit as some have, make sure you get the failover cluster because this works much better than anything I have seen yet.... Wish they had snapshot though... _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

recovering data from user's snapshot directory?
by brad＠ThoughtWorks.com 22 May '01

22 May '01

We have a few employees that have left the company and I need to get their data back from their snapshot directories (the original files and folders were deleted as well as the usernames). The volume is a CIFS homedrive setup and if I try to take ownership of the folders under the snapshot directory, I cannot. I also cannot give myself read access to the folder. Has anyone else has this problem? I'm logging in via the administrator account and it still does not work. Thanks in advance for your help.

Bluearc Si7500 NAS box (Dilbert who?)
by Laura Forenti 22 May '01

22 May '01

Get a life Dilbert... I have actually spoken with someone who is under NDA testing one of these NAS appliances. As with all appliances, the features will be coming slowly but I was told that a cluster upgrade only involved a ten-second outage? Imagine if that was true! Has anyone heard anything about the cluster config? -Laura _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/

RE: Connecting a spectralogic Gator Tape Library to an 840
by Collie, Michael 22 May '01

22 May '01

The supported Fibre Channel HBAs for the F840 are as follows: Fibre Channel Host Bus Adapters: Qlogic X2043A (optical) Qlogic X2045A (2 channel optical) Qlogic X2041A (copper) One F-QIP card in the Spectra 12000 can control 4 drives. In this case, you will need only one X2043A (assuming you want optical) HBA connected to that F-QIP. If you have more than 4 drives in the library then your options are the X2045A or X2043A.

I have two cards on the library, can I have two cards on the netapp? or can I have a dual card on the netapp? One additional bit of info, the library and netapp are about 50 meters apart. Thanks

RE: Connecting a spectralogic Gator Tape Library to an 840
by Joe Luchtenberg 22 May '01

You have tremendous flexibility with those platforms. You can go with a single X2043A per filer and daisy chain the busses on the QIP at the Gator, or you can use the X2045A to connect to both FC ports for HA. You can direct connect or go through a fibre switch. In fact, NetApp just announced their OSN FC fabric tape b/u solutions: Press release: http://www.netapp.com/news/press/2001/news_rel_20010508b.html Spectra Logic solution/requirements: http://www.netapp.com/osn/info/gbe/spectralogic.html According to the documentation in the second link, you can only connect a single FC port from the F-QIP in the certified solution. However, you don't have to go with the OSN FC fabric solution. There are other certified solutions, such as the old Gold solution with the Vixel 8100 or direct connect (as I mentioned above). Some considerations: - with current AIT-2 specs you can fully occupy 4 drives (62.4MB/sec compressed total) with a single FC connection at 100MB/sec. However, if you should upgrade to AIT-3 (due out this summer/fall; 124.8MB/sec compressed total), then you will need to connect to both FC ports on the F-QIP to keep the drives busy - AIT advantages vs. DLT: 1. investment protection/backwards compatibility/future development path through AIT-6 (biggest differentiator in my estimation) 2. price/performance 3. density 4. MIC 5. slower media speed ==> less wear & tear; faster/more accurate seeks; better MTBF I'm a sales guy (and therefore obviously biased), but I can sell either one and make the same money off both. HTH. Happy to elaborate on anything.

RE: Question on OS upgrades when clustered
by Jankowski Ted-CTJ012 22 May '01

22 May '01

When I've done this (during a downtime), I download the o/s onto both boxes and reboot them at the same time. I tend to be a little daring with my boxes though. -Ted -----Original Message----- From: Allen, Pat [mailto:pat@mbari.org] Sent: Friday, May 18, 2001 1:21 PM To: Toasters (E-mail) Subject: Question on OS upgrades when clustered Hi all, I've just clustered a couple of F740's. I've got about 6 years of experience upgrading the OS on filers but have never done it on a cluster before. Do I need to do anything special to insure that both boxes are on the same version of the operating system? I will be going from 6.0.1R3 to 6.1R1.

Re: du without the .snapshot
by Tom Reingold 22 May '01

22 May '01

Here is a perl script my coworker wrote that pretty closely mimics the du command. The solutions I saw here yesterday aren't close enough for my taste. Du should print a summary at the end of output.
