At a recent NetApp presentation it was mention in passing that RAID-DP fails if a double disk failure happens to hit the two parity disk. Is this true ? George

RE: experience with iSCSI from W2K3 servers?
by Alan Biren 04 Apr '05

04 Apr '05

When working with iSCSI on W2K3 server or any Microsoft OS, the key is the networking component. If it is at all possible, I enable Jumbo Frames and create a separate VLAN for the storage traffic, very similar to a FC SAN. You also want to make sure that you Bind the Volumes and make the target Persistent. I also use a VIF (multi or single) as well as etherchannels and NIC Teaming to try to aggregate bandwidth. If you are able to use SnapDrive, it'll make connecting and managing the LUNs much easier, especially if you will need to increase their size. I've only used HP Proliant servers. I've used the MS iSCSI Initiator (all versions) and the QLOGIC 4010. If you are going to cluster and iSCSI environment, I recommend reading MS Article 883397. I would follow the steps even if it not a pure iSCSI environment. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Rob Winters Sent: Wednesday, March 30, 2005 5:39 PM To: toasters(a)mathworks.com Subject: experience with iSCSI from W2K3 servers?

How to use non netapp disks on an F720 netapp ?
by Anton 04 Apr '05

04 Apr '05

Hello, I have an old F720 it has 3 9gig drives , but 2 of them are dead , i would love to be able to reuse this netapp but netapp drives are too expensive for me , as i use this stuff at home i'm not able to invest more . I tried to make an 72gig fc drive to be reconized by the netapp but without any succes (i tried to downgrade the netapp to its very old version also) . But it sill dont want to flash the firmware on this segate drive . Is there any way to make it work ? I'm thinking about mount the fc array on an linux with an fc card and flash the disk firmware with the netapp firmware using segate flash utility . Any help would be very apreciable . thanks an

Re: Upgrading to 6.5

Robert - Note what platform you'll be installing on. For example, if you have a cluster, 6.5.1 had a bug that caused one machine to lose time sync with the other. If you have a certain NVRAM board, you'd get bogus messages that the NVRAM was failing. Make sure you go, at least, to 6.5.2. You'll miss some significant bugs there.

SMB signing and my F760 ...
by Waters, G Scott RDECOM(THE LOG.SEC TEAM) 31 Mar '05

31 Mar '05

Does anyone have any experience with SMB signing?? We recently applied a DEBUG version of DoT 6.5.3 to our F760 in order to take advantage of SMB signing - a feature that won't be available until a later release of DoT 7.x - which won't be available for the F760's. With the SMB signing turned on we are seeing a much higher load on the filer's CPUs. NetApp analyzed some Performance Data and say that the SMB signing module is adding a 30% load to our FILER CPUs. What would you think? Is SMB signing that CPU intensive or would you think it could be sloppy code?? The performance hit is soo drastic I really have a hard time believing it is anything but bad coding (or maybe a little of both). NetApp Support's solution was to turn off SMB signing. Of course they were not thinking at all when they said that - because why would anyone apply a DEBUG release of an OS whose only function was to add SMB signing if they did not need SMB signing???? Fortunately we have a new filer waiting for a data migration ... but I have serious concerns as to what this is going to do to my new filer. What does a 30% CPU load increase translate to on a FAS960?? ... 10% ... 15%?? How soon before I have to buy another FILER?? I don't want to drop this ... but NetApp doesn't want to pursue any resolution other than new hardware. Anyway ... does anyone have any comments / suggestions?? - Scott W.

RE: Netapp trunking - no performance gain
by david byte 30 Mar '05

30 Mar '05

The catch with trunking is that a single host will not see performance gains, unless they are load balancing across 2 nics and the filer is load balancing in the exact same manner. (not likely, but it can occur as aaron notes) Generally, trunking is used for load aggregation to provide higher performance to a larger number of clients. If you are looking for higher throughput that about 100MB/s you should be talking with your Network Appliance SE about assisting in the configuration and design of the system.

I then took two 10/100 cards on a server and bound them togther and enabled sharing on the ports for the switch too. I went from pushing about 10MB/sec from the server to 20MB/sec. As this is well below the theoretical maximum for two gige ports trunked together, 250MB/sec (125MB/sec each), the problem is that pushing so little data makes it hard to see how effectively the gige trunk works.

Why do 'some' people that reply to these emails not read them first?? Tim, if you bothered to read my origignal emails you would see that it is you that is ignorant by replying in that fashion. If you can't be more helpful why not refrain from answering? I maybe inexerienced as far as reusing NetApp FC disks in this fashion, but as per my previous emails you would have seen that I know enough with out the 100's of people telling me that they need to be low level formatted - see 1 st and subsequent emails. That's not the problem I've got that done but I can not format them ala Windows 512 sectors. See previous comments about diskpart & gdisk32, etc. As for the response sugesting using a different shelf, well that wouldn't be reusing the DS14 would it? It's something I may have to do, but before doing so I thought I'd ask to see if anyone could suggest a way of 'reusing' the DS14 shelves. Now, your point about disk manufactures utilities to format the disks is a bit more along the right lines, at least it addresses the question. The details about the mylex is helpful, I'll check that out.

A simple 'no thanks' would have done. I had no intention of bothering you. I was simply trying to help as I could tell from your previous posts that you were completely ignorant when it comes to fibre channel disk firmware, block size, formatting, RAID, etc. I was trying to provide a simple solution that you might understand. Your best option in my opinion would be using a 16 bay shelf with a hardware RAID module from the same manufacturer. I would use disks that have factory generic firmware and format them 512 bps. If you are set on using NetApp DS14's, then at least format the disks 512bps. Disk manufacturers provide free utilities and there are several expensive commercial sofftware options to accomplish this. Your hardware RAID options are limited. I can suggest the Mylex ExtremeRAID 3000 which is a PCI hardware fibre channel RAID card which is Windows compatible. This is a copper card with two HSSDC connectors so depending on which style LRC's you have, you may need to do some optical to copper conversion. Now the LRC and the disk firmware were designed for NetApp, so you would still be better off with generic disk firmware and a shelf designed to be Windows compatible. Better yet, just put these DS14's back on a filer and run FCP.

Ian, I apologize. A simple 'no thanks' would have done. I had no intention of bothering you. I was simply trying to help as I could tell from your previous posts that you were completely ignorant when it comes to fibre channel disk firmware, block size, formatting, RAID, etc. I was trying to provide a simple solution that you might understand. Your best option in my opinion would be using a 16 bay shelf with a hardware RAID module from the same manufacturer. I would use disks that have factory generic firmware and format them 512 bps. If you are set on using NetApp DS14's, then at least format the disks 512bps. Disk manufacturers provide free utilities and there are several expensive commercial sofftware options to accomplish this. Your hardware RAID options are limited. I can suggest the Mylex ExtremeRAID 3000 which is a PCI hardware fibre channel RAID card which is Windows compatible. This is a copper card with two HSSDC connectors so depending on which style LRC's you have, you may need to do some optical to copper conversion. Now the LRC and the disk firmware were designed for NetApp, so you would still be better off with generic disk firmware and a shelf designed to be Windows compatible. Better yet, just put these DS14's back on a filer and run FCP.

Netapp trunking - no performance gain
by Chris Moll 25 Mar '05

25 Mar '05

Has anyone gotten any performance gains from network interface trunking with a netapp? So far I haven't.... my suspicion is that I don't have the switch setup right. ----- More details: I'm trying to setup trunking on a netapp connected to a Cisco 3550 gigabit switch (OS vers.12 on the switch). The odd thing is that when I setup two gigabit lines trunked together from the netapp to the switch I saw no improvement in thoughtput compared to a single gigabit line. As a test I set up four 100Mbit interfaces trunked together from the netapp to the switch. Again, I see the same throughput as with a single 100Mbit interface alone - there was no gain in throughput from adding three more interfaces. (Measured by connecting a Sun to the switch with a gigabit interface). The trunking worked even before I set anything on the switch. The only thing I knew to do on the switch was put the interfaces in a channel group: switch> interface range GigabitEthernet1/0/17 - 18 switch> channel-group 1 mode on switch> end ...but still no change in throughput (this worked with sun trunking, and there I did see a gain in throughput). netapp> vif create multi romvif0 -b rr e4a e4b e4c e4d netstat and vif status both show roughly equal numbers of packets on all four interfaces; all four are definitely being used. -Chris Moll Lawrence Berkeley National Laboratory
