Other OPS?
by Page, Jeremy 05 Jun '09

05 Jun '09

What causes other ops? I understand that pretty much everything that hits the filer requires something but I am seeing what looks like a very high number of other ops when I do a stats show. Does this indicate a problem or is it just a busy box? It's a mixed mode volume. Just trying to figure out what's causing it to work so hard.

Convert F825 to FAS940
by ifstat 05 Jun '09

05 Jun '09

Hi I have a F825, just lazying about, being absolutaley useless to me. I was wondering is there a way to reset it's bios or something along that line, so that it thinks it is a FAS940, the reason for this is my testing system is a FAS940 and i have data ontap 7.3.1 on it. The F825 only goes upto 7.2.x so i can't do snapmirror from test site "A" to test site "B". It has to be A to B because of A i have DS14MK4 and on site "B" I have DSFC9 storage. I know that this is not a supported or even midly recommended by Netapp but i just want to test the operations manager data protection, etc. Anyone done this or has any ideas, i'm keen to try.

Hello, we are retiring our VTL 600 head and would like add the disk shelfs to our existing Netapp 3140. Does anyone know if this is possible or has maybe done something similar? Thanks

Hmm... will you be able to move volumes live? I assume you'll need to have the free space in the destination aggr to hold the entire vol you're moving, but that should be ok then. Just keeping the data live and in production during such moves would be a huge help. Glenn> If they bump the limit beyond 32TB, I care less - most of our Glenn> volumes we keep rather small to assist with backup limitations Glenn> and/or reduction of single points of failure. Sure, I agree too. I might even start to use more volumes then, instead of qtrees within volumes. John

This is not the case. Upgrades to Data ONTAP 8.0 can be performed non-disruptively from 7.3 releases. If you have not yet upgraded to a 7.3 release you will need to follow the guidelines to non-disruptively upgrade to the latest 7.3 release before upgrading to 8.0.

FAS2050C questions (clustering)
by Ray Van Dolson 03 Jun '09

03 Jun '09

I'm the proud new owner of an IBM N3600 A20 (rebranded FAS2050C) with 20x30GB SAS disks. I'm trying to determine the best way to get this thing set up, and realized I have only a bit of a fuzzy understanding as to how the clustering or failover filer head should work. My initial thoughts were to aim for the following setup: - Set up all 20 disks in a RAID-DP aggregate with one spare (17 data, 2 parity and one spare, or maybe two spares). - Bond a NIC from the first controller with a NIC from the second controller to give us a 2Gbps connection to our "storage network". - Third and fourth NIC's would go to our regular network. My hope was that I could lose one filer head and the other would take over seamlessly. We'd lose half of our network bandwidth but still be up and running. However, it sounds like my understanding of how the clustering works might have been a bit flawed and that I actually need to treat the filer heads as two separate filers. So I may be forced to do something like the following: - Split my disks up between the two filers (7 data, 2 parity, one spare -- or maybe I can have one spare available to both heads). - Probably can't team NIC's from multiple filer heads meaning if I team the two NIC's on the filer I can no longer connect to my management network. I probably need to order more NIC's :( - If I lose one head, I lose one aggregate unless manual intervention is taken. - Each filer has a different hostname/IP for network access. This maybe gives me better performance, but at the expense of total disk space and flexibility if my understanding is correct. Maybe someone could help clear this up. It doesn't appear IBM has a RedBook on clustering... I'm searching around in NOW and have come across the Data ONTAP 7.3 Active/Active Configuration Guide which I am now reading. Is there something similar for Active/Passive setups (which seems to be more what I am after) or other documents that would be recommended reading? Any advice or best practices? This filer will be serving NFS to a pair of ESX servers. We plan to add a second shelf of disks later this year. Thanks in advance. No sales inquiries please. Ray

Thanks all. Great advice. So, my question is: if the second head can take over the personality of the failed head, why do I need to allocate any disks at all to the second head to begin with? Just a design thing? I'll probably do the even split thing.... and look into ordering additional NIC's. Can I have a "spare" that is available to either aggregate on either filer? This way I could do two RAID-DP's on each head with one common "spare" disk and rely on 4hr support to get me replacement disks quickly. Ray

HSM/ILM for Netapp
by Babar Haq 03 Jun '09

03 Jun '09

Hi all, IHAC who is searching for a product that can provide HSM/ILM function for massive NAS environment. This product can be either a hardware appliance, a software, or combination of both that can provide a total transparent solution for our user (i.e. regardless where is the physical data location, user can remain using it old logical path to access the same data) with tiered storage. So far I can only identify two products one hardware Acopia and the other one is software approach CommVault. Both have it pros and cons but the biggest challenges for both products are not able to manage snapshot and do not go down to qtree level. Thanks in advance.

This doesn't help when you do NDMP backups, does it? Also, do you *ever* trust version X.0 software? *grin* I'm not moving to CommVault 8.x or OnTap 7.3.x until they're more stable and widely tested. I need stability at work. John

ESX volume design question
by steve klise 02 Jun '09

02 Jun '09

What would you do? ESX 3.5 running all windows servers; FCP with all fiber drives We have an existing 6030 with 1 aggr, 1 large volume with ~5 LUNS 500GB a piece; running DOT 7.24. (upgrading soon, so no dedupe running yet). We have a new HA 6040 (PAM cards) =). The existing volume on the 6030 is still at 100 percent fractional reserve. We have SMVI running in our test environment, but not in prod yet. We wanted to snapmirror from the 6030 to the 6040 and visa versa. The 6040 is running 7.3.1.1 so I can only go from the 6030 to the 6040 for now. No vmware on the 6040 yet. Question: I have 3 shelves each for each head (6 300gb total for the 6040) and 1 big aggr on the 6030, 11.5TB agr 4.97used in the volume on the 6030. I was thinking of having the volumes for the 6040 @ 750GB and 1 LUN. I am averaging ~20 windows boxes. I figured when SMVI runs, it is only 1 snapmirror update vs running the job with allt he LUNS in 1 big aggr and multiple snapmirrors happening. I will make the fractional reserve set to 50% on the 6040 with thin provisioning at the LUN level, and dedupe. Pros: I think its more granular. Having to find a location for 6TB is a bit difficult Con: Not as much dedupe by having all VM's in 1 volume. Thoughts, experiences, gotchas.? -- View this message in context: http://www.nabble.com/ESX-volume-design-question-tp23821864p23821864.html Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.
