Hello all,
Having decided to upgrade our VMware ESX servers to 3.5 from 3.0.2, we have come across a strange problem.
On each ESX server we have 3 VSwitches, 2 of them each contain a service console port and VMkernel port. One of Vswitches we have been using for Iscsi in ESX 3.0.2 without any problems. (The first VMkernel port is enabled for Vmotion and is routable)
Once we upgraded to 3.5 we have noticed that the filer now shows 2 sessions from the esx host, one from each of the VMkernel ports, however one of the paths is routed and one of the paths is switched. On the ESX host we see each LUN twice, with different paths but with the same canonical path.
Does anyone know how to restrict what targets are being sent by the filer based on the interface ? We cannot disable Iscsi on any of the interfaces on the filer.
Or does anyone have any other bright ideas ?
Thanks
Matt

easy.
you could use the spec sheets to figure it out... Get you last electric bill. It should tell you how much you pay per kw/hour. Figure out how many watts you will be using... Figure about 440W per loaded shelf and 220W per head (660W, .660KiloWatts) If I am doing the right math (and I may be waaay off here): .660KW * 24 Hours = 15.84 Kw/day * 30 days = 475.2 KW/month * .10 (10 cents) = 47.52/month
My electric co has peak/off-peak and intermediate that ranges from .08 -> .18 per kw/hour The average is supposed to be .10 per kw/hour.
like I said...I could be waaayyy off here.

Hi Matt I'm still trying to fully understand the new functionailty of the ESX3.5 SW iSCSI stack, but it seems they've made some improvements in MCS (Multi Connection Sessions) or some other technology that allows the iSCSI SW stack to be aware of and fail over between paths.
I'm 90% sure of this so far, but ...
I would leave the paths as they are. You can use tpgroups (documented in the man pages and Block Access Guide) on the filer to restrict iSCSI traffic to certain ports for certain igroups, but I think you're better off leaving the other path as a failover. In ESX, set the preferred path of the LUN(s) to go through the most direct network or the back-end / storage network if that's what you have.
esxcfg-mpath -l on the CLI should show you similar info to what you see in the VI Client. vmkiscsi-ls (one word / no space) will list all the target portals that iSCSI knows about. They should look like this: (I've snipped some other junk) [root@esx1 mcs_test]# esxcfg-mpath -l Disk vmhba32:2:105 /dev/sdg (10240MB) has 2 paths and policy of Fixed iScsi sw iqn.1998-01.com.vmware:esx1-2e0f4af9<->iqn.1992-08.com.netapp:sn.1180429 01 vmhba32:2:105 On active preferred iScsi sw iqn.1998-01.com.vmware:esx1-2e0f4af9<->iqn.1992-08.com.netapp:sn.1180429 01 vmhba32:4:105 On

Note the TARGET ID for the portals listed as ESTABLISHED will match the target ID in the vmhba LUN name, in my case, 2 and 4. So from the TARGET ID, you can get the corresponding IP address, and that gives you the preferred target. You use esxcfg-mpath to set the preferred path:
[root@esx1 mcs_test]# esxcfg-mpath -L vmhba32:2:105 -P vmhba32:4:105 -f -p fixed Setting vmhba32:2:105 -- vmhba32:4:105 as preferred path

Your iSCSI traffic will use the storage network, until it breaks, at which time I/O (and possibly more) will hang for ~30 seconds while ESX figures out that the path failed and fails over to the other target on the other network. I tested that by downing the preferred interface, and the service console hung for a few seconds, then picked back up, and esxcfg-mapth showed the pref path dead, and active on the other path. vmkiscsi-ls showed the session status as "Dropped" with a timestamp.
I have not yet played with the new path policies, so there may be a better option than preferred and fixed. I'm also wondering if this might lead to load balancing in iSCSI...
Please let us know how this goes for you!
Thanks
Peter

Peter,
Thanks for the info, it seems that Vmware have started using a different Iscsi initiator, on ESX 3.5 (in 3.0.2 it was a Cisco Driver, and in 3.5 is the SFnet driver)
It seems to have picked the preferred path via the directly connected network, rather than the routed network. The main cause of concern at the moment is that it appears to be establishing a ISCSI session from the VMkernel port associated with Vmotion.
We have restricted the traffic on the router, to stop this from occurring that the moment.
If you come up with any more information on what has improved or not improved with Iscsi in ESX 3.5 when working with Netapp, then please let us know, as it appears even VMware don't know.
Thanks
Matt

Can a simulator be used for real disk? E.g. I build a linux box and attach 36 external disks to it, would the simulator be able to see that storage? If so, how? Does anyone have instruction on how to do this?
Thanks,
James
Nice. I'll check the price, would this $300 be used?

It will also keep the room it is installed in nice and warm. Fine in the winter, maybe not in the summer. . .
Even if it's $75 more per month, then that's still doable.

easy.
you could use the spec sheets to figure it out... Get you last electric bill. It should tell you how much you pay per kw/hour. Figure out how many watts you will be using... Figure about 440W per loaded shelf and 220W per head (660W, .660KiloWatts) If I am doing the right math (and I may be waaay off here): .660KW * 24 Hours = 15.84 Kw/day * 30 days = 475.2 KW/month * .10 (10 cents) = 47.52/month
My electric co has peak/off-peak and intermediate that ranges from .08 -> .18 per kw/hour The average is supposed to be .10 per kw/hour.
like I said...I could be waaayyy off here.

The S300 also uses a lot less power. It's a nice little system, but I am a bit biased!

I know this probably doesn't work. But if I purchase a old filer, would the simulator licenses work on that? How much does the licenses cost anyway?

It's not supported, but it's all there. We have several now and they're all managed with ssh and vi!
No. The simulator liceses only work on simulators, not real filers. Licenses are priced by platform, but older (i.e. EOL platforms) may not have prices.
There's been talk about "home use" licensing, but I'm not aware if it was ever implemented.

You can avoid unpleasant utility surprises by using this nifty gizmo:
http://www.newegg.com/Product/Product.aspx?Item=N82E16882715001
Here in California power is at least 14 cents/kwh (tiered, so your rate goes up if you consume more), so do the math.
I bought this baby and it paid itself off in a month.
Its cool to be a cheapskate.

Hi,
One additional question regarding this topic. We're planing the usage of netapp sims, for somekind of small data replication from our central datacenter to home offices. Today we're syncing the data with unix tools, but we think about implementing a netapp sim, because of some very useful netapp functios. The amount will be about 1-2gb, which has to be mirrored each day to the home offices. I think we can optimize speed and and we would be able to throttle bandwith with the usage of the simulators snapmirror. The solution will be a blackbox for the users, just only for automatic syncing the data from our headquarter to their private office. For this usage, netapp functions provide very powerful and useful methods, thats why I'm thinking about this...
What do you think about these ideas? Are there any restrictions, which do not allow the commercial use of netapp sims? Or do you think it's just an unrealistic idea, to implement such a solution?
Regards Andreas

The biggest hurdle you'll have is no support for your simulators. So depending on how mission critical this replication is, you'll need to decide if it's worth it for the price.
I'm not saying it won't work, I believe it will. But if you have any problems down the line, tech support will be limited as to what they can do since the simulators don't have support contracts.

Sorry to get all legal about this, but the simulator is subject to a license and is not freely deployable. I would advise reading license.txt which is included in the simulator package, which constrains the use of the simulator to specific scenarios.
IANAL (I Am Not A Lawyer), but you may know someone that is and can help interpreting it.

The biggest hurdle you'll have is no support for your simulators. So depending on how mission critical this replication is, you'll need to decide if it's worth it for the price.
I'm not saying it won't work, I believe it will. But if you have any problems down the line, tech support will be limited as to what they can do since the simulators don't have support contracts.

Hi,
One additional question regarding this topic. We're planing the usage of netapp sims, for somekind of small data replication from our central datacenter to home offices. Today we're syncing the data with unix tools, but we think about implementing a netapp sim, because of some very useful netapp functios. The amount will be about 1-2gb, which has to be mirrored each day to the home offices. I think we can optimize speed and and we would be able to throttle bandwith with the usage of the simulators snapmirror. The solution will be a blackbox for the users, just only for automatic syncing the data from our headquarter to their private office. For this usage, netapp functions provide very powerful and useful methods, thats why I'm thinking about this...
What do you think about these ideas? Are there any restrictions, which do not allow the commercial use of netapp sims? Or do you think it's just an unrealistic idea, to implement such a solution?
Regards Andreas

No. The simulator liceses only work on simulators, not real filers. Licenses are priced by platform, but older (i.e. EOL platforms) may not have prices.
There's been talk about "home use" licensing, but I'm not aware if it was ever implemented.

I know this probably doesn't work. But if I purchase a old filer, would the simulator licenses work on that? How much does the licenses cost anyway?

So this data is obviously important to you, and something that you want to protect, this is why you're doing offsite data replication. I would think you would be much better off buying a filer, but since you're using the simulator, I'm assuming that's a no-go. I'm assuming further, since you have the simulator, you have access to a unix/linux box to run it on. Here's what I would propose as an alternative:
Mount the volumes you want to sync off site on a unix box. Open port 22 on your firewall to the remote site you want to sync your data to. Follow the guide below, but add the option "-e 'ssh'" to the rsync commands, and set the source to be "ip.of.unix.source:/path/to/mounted/volumes" and the destination the location on the remote destination's unix machine.
This is a fairly straight forward process and uses standard methods common for doing backups in the unix world. It will preserve your premissions and allow you to recover from a specific point in time, just like snapshots do. It's not *quite* as nice, but I would imagine it would be preferable to relying on a sim. Obviously, it does require a certain comfort level with unix, so your mileage may vary.

Nick,
Don't get me wrong. This was just an idea for an alternative, you described below. These ideas with netapp sims should be used for field stuff or things like that. It is not planed for whole branches, only for several people, that's why a real filer doesn't make sense and would be completely oversized. So I'm looking for a solution to optimize these things and netapp functions may improve the whole process. I want to give it a try, if it's really competitive with standard unix methods, that are already well proven.
Of course, support questions and license restrictions are other points, we have to deal with...

I will be purchasing some NetApp equipment (yes the simulator is cheaper) and here is the quote;
F820 = $950.00 FC9 = $170.00/Each 225B 36GB HDD = $135.00/Each 226A 73GB = $190.00/Each
Of course I am going to cheaper route, but just wanted to get some comments on this.

are you ready for a wallop on your electric bill...
I used to stage demo equipment at home. Just running a power hungry netapp over the weeked caused my electric bill to spike...

easy.
you could use the spec sheets to figure it out... Get you last electric bill. It should tell you how much you pay per kw/hour. Figure out how many watts you will be using... Figure about 440W per loaded shelf and 220W per head (660W, .660KiloWatts) If I am doing the right math (and I may be waaay off here): .660KW * 24 Hours = 15.84 Kw/day * 30 days = 475.2 KW/month * .10 (10 cents) = 47.52/month
My electric co has peak/off-peak and intermediate that ranges from .08 -> .18 per kw/hour The average is supposed to be .10 per kw/hour.
like I said...I could be waaayyy off here.

Ouch. Power prices in CA must be through the roof. In OR I'm paying about 8-9 cents/KWh - and that's opting for the expensive "green power" to assuage my guilt about running three full racks of equipment in my basement.
I've run toasters at home for a long time. For years an F330 and a single shelf of 4GB drives was plenty of space for me, supporting a small home network of a dozen various Unix boxes. For the last three years I've run an F720 with a single shelf of 36GB drives, supporting a pile of Suns (half a dozen 2- and 4-way 220/420/280R class) and a couple of Dells (2-way 2450s), plus network kit and a DLT library. At the peak this winter my bill hit $325, but it typically runs around $250-280/mo - about $9/day. The server room is about 75% of that, and the NetApp is no more power-hungry than any of the other machines. If I could afford it, I'd probably buy a Sun T2000 and consolidate the servers before I'd worry about the cost of the NetApp!
Obviously if you need a huge amount of storage and many shelves of drives, then of course an older box like the F700- or F800-series will be more expensive. But for sensible home use, a single DS-9 of 72GB disks is plenty of space, and you get the benefits of running a real NetApp. Every time someone says "you could replace that with a cheap linux box and some 500GB drives!" I just smile and nod. I've run toasters since 1995 and NEVER ONCE lost data. Can't say that about _any_ other storage I've ever used. That's worth a few extra dollars on the power bill, in my judgement. You'll have to do your own cost/benefit analysis, of course.
So, yes, it's "more expensive." But I find it a small price for peace of mind.

I suggested to my wife that we could save a lot of money on power by turning off the filer and getting some cheap SATA drives.

So, yes, it's "more expensive." But I find it a small price for peace of mind.
Just another data point,

So I should be able to install the latest version of ONTAP or at least 7.

I will be purchasing some NetApp equipment (yes the simulator is cheaper) and here is the quote;
F820 = $950.00 FC9 = $170.00/Each 225B 36GB HDD = $135.00/Each 226A 73GB = $190.00/Each
Of course I am going to cheaper route, but just wanted to get some comments on this.

Hi,
No the simulator licenses only work on a simulator, not on real iron...
Best regards, Filip

No. The simulator is limited to 28 1GB virtual disks.

Regarding your question on simulator: it does not work with shelves hd, it relay ONLY on the Linux box file system!!!
It simulates...a loto f things and more as I told you, but not the real world
And, more. You speak to buy an old filer (used...): if you buy the filer you get the licenses built in...the ones it came from NetApp and the other installed by preceding user.
For your other question I presume F810 with 7.1.2.1 but you could have issues with firmware...

The simulator doesn't require a typed-in license the way a filer does. So no, there's nothing from there that would be useful on real hardware.
Hi James,
The license codes for the simulator are unique to that platform and will not work on a filer.

What is the older type of filer that I am able to install ONTAP v7 on?
James
We've successfully used 7.2.3 on a FAS820 in our lab, but it is _not_ supported. If this is a situation where you'll have production data, you're better off sticking with officially supported releases.

Be aware also that the simulator's data is only as safe as the underlying filesystem. Its "disks" are just files on ext3 or whatever.

The simulator only accesses disks represented as files.
-- Michael Barrow michael at michaelbarrow dot name
A simulator doesn't see disks directly. It sees files that it treats as disks. The sizes and number of disks is also quite limited (I think the disks are limited to 1GB and you can only have something like 28 disks per sim).

Are you searching for a "free" NetApp? J
Well, more seriously answer.
You can install a simulator on any disk device in a Linux box, you can create a mount point to your external disks and the install there the sim but the real problem is that the sim creates its own virtual disks with a maximun size of 1024 MB each, so you can also "theoretically" have a 500 G storage for you sim but composed of hundreds of virtual disks and dozens of raid groups to be assembled in aggregates...
It's a simulator that can do everything (except FCP) but do not exagerate with its usage in a production environment J
If you want a NAS or an iSCSI SAN on you external storage under Linux there are several free software for Linux that can do the job.
