I-SCSI or Fibre Channel for SAP on ESX ?

Hello,
i have 4 ESXI Hosts with 2-6 vmware machines. Every machine contains a NW 2004s system (test, demo, education) with 8 GB ram and MaxDB database with 50-100 GB. Today the machines run with local Harddisk, but we plan to buy a SAN. I prefer a low cost fibre channel solution on basis of
Infortrend EonStor S16F-R1840 (RAID-System) and Qlogic SANbox 5800 V (SAN Hardware), but our central it administrator wants a solution based on 10 Gb i-scsi.
I read several blogs and articles, but im am really unsure which technology we should use.
Greetings
Heiko

We have our entire VMware landscape running on iSCSI SAN's, including SAP, Exchange, File/Print services. Before we went this direction we tested what our needs were to determine which option would best meet our needs. We found that the iSCSI solution would more than cover our requirements. Couple this with the fact that iSCSI uses copper, infastructure costs would also be lower.
We are relatively a small shop, approx 200 users on 3 ESX hosts with 35 VM's, so the iSCSI option was a good fit for us. I would recommend trying to find what your requirements are for performance on the SAN, this will help you determine which technology to go with. In our case both cost and performance were in the favor of iSCSI and that is the direction we went and have had no problems. Hope this helps.

Looking for a Fibre-Channel interface

Does there exist a Fiber Optic communications interface, specifically "Fibre-Channel" for which LabVIEW drivers exist?
Perhaps one of the select integrators may have one or know of one.

I am working a project now that includes a "Fibre-Channel" phase in a future phase. We have done a lot of research into this area and are developing benchmarking systems that will let us quantify the determinism of various transport mediums. The current implementation is building on a SCRAMnet gt fiber network to do the measurements.

USCSICMD ioctl calls for Fibre Channel(FC) devices on Solaris 10?

Hi ,
I have wrtitten a small C program that issues USCSICMD ioctl call to the tape devices attached on solaris sparc 10. I was able to get the required information from all SCSI tape devices attached using the utility. But, whenever it is run on FC attached tape drives , the program returns an error saying "Inappropriate ioctl for device".
bash-2.05# inquiry /devices/pci@1f,4000/fibre-channel@2/fp@0,0:devctl
inquiry: /devices/pci@1f,4000/fibre-channel@2/fp@0,0:devctl: scsi inquiry failed: Inappropriate ioctl for device
Is it possible to make an USCSICMD ioctl on FC attached tape devices ?. Can someone please provide an example if possible.
Thanks,
Naveen

I don't see why not, I use the same ioctl to talk to fc-attached disk drives, and enclosure devices. I have used the same ioctl to also talk to scsi-attached tapes. Maybe this is a bug that is specific to your FC device driver or firmware, did you investigate with the HBA vendor and make sure everything is current?

Easiest solution for adding Fibre Channel Tape Backup to Xserve RAID setup

I'm interested in getting a Fibre Channel LTO-3 tape library such as the Exabyte 221L for my Xserve RAID/Xserve G5 setup. I realize there are SCSI LTO-3 solutions that are less expensive than FC, but I'd prefer not to have to add a SCSI card to my Xserve, mainly because I'd have to pull the video card and run the server headless (horrors!). However, I understand that I must get a Fibre Channel switch to allow the LTO library, the Xserve, and the Xserve RAID to communicate... you can't just daisy chain FC devices. The least expensive switch I can find is the new QLogtic SANbox 3050 for about $1800. For my situation, in which these will be the only FC devices I'll probably ever use, does this switch sound appropriate? The specs on the switch can be found here: http://www.qlogic.com/products/sanbox/sanbox_3050.asp.
Xserve RAID & Xserve G5 Mac OS X (10.4.5)

For simple environments like yours, it's trivially easy. You must plug everything in, and you're good to go... as simple as a network switch.
Now if you start adding multiple hosts (i.e. plug in a second Xserve or G5), you need to be careful, because in the default configuration everything is "wide open," so every device can see every storage LUN. This would actually be problematic, as systems could (actually, would) corrupt each other's storage. When you get to this point, you'll need to look at either zoning the ports on the switch, or using LUN masking on the Xserve RAID to allocate specific pieces of storage to specific hosts.
But for now, just get the switch, plug everything in, and you're off.
BTW if you mark "answered" for me, versus for the thread overall, it helps me out a bit in this forum ranking system, whatever it is.
Cheers.

How to obtain target WWN for a LUN On Windows 2012 R2 Hyper-V with Fibre Channel SAN

I have a large collection of Hyper-V hosts for which I would like to retrieve the target WNN and LUN ID for the LUNs visible on each host. By target WWN I mean the storage array's WWN.
I have tried using the root\wmi namespace to retrieve MS_SMHBA_PORT_LUN instances, but I get 0 instances back.
I get instances of MSFC_FibrePortHBAAttributes back, but those only tell me the local host's HBA WWN, not the target information.
This information must be stored somewhere, because you can't access the LUN without it, I hope there is a way to retrieve it. Is there? Or is it write only during LUN setup?

Plugin for EMC VMAX fibre channel storage

I am new to Oracle VM and VM Manager. After reading the documentation, I believe that I need a plugin for VM Manager to discover our EMC VMAX Fibre Channel SAN LUNs. As it is now, discovery on its own does not show the LUNs. Where can I get this plugin? I contacted EMC and they know nothing about a plugin.

It will use the Unmanaged FC Storage Array functionality. If you are not seeing your VMAX luns, check that multipathd is started on your Oracle VM Server and that multipath.conf has the correct device {} stanza for the VMAX.

EWDM for 16 Gbps fibre channel rates

Can EWDM with amplifier support fibre channel SAN rates of 16 Gbps?

If you already own cisco EWDM, then check with vendor of 16Gbps SAN that can they provide 16Gbps Optical Transreceiver (SFP) for wavelengths supported by EWDM. As cisco only providing 10G SFP. For optical system it doesnot matter whether it is 1/10/16/40 higher rates can go lesser distance without amplification. Only thing need to check whether the distance you have between EWDM system will be able to support that distance at 16Gbps rate or you need optical amplifier etc. You need to see your power budget.
If you don't have Cisco EWDM then check with SAN 16Gbps vendor what they suggest. As you have many variables to see which will be difficult for you to manage if you are new to DWDM.

Party communication channel for multiple stores with multiple user id and passwords in sap pi

Hi Exeperts,
I have a scenario proxy to SAOP . where i am sending some information from my stores to third party company with single user id and password in communication channel.
but requirement is changed now i have 20 stores with 20 user id and password for communication channel.how can i achieve this requirement?
Can i create 20 communication channels for 20 stores or can handle through the party based communication ?
Please help us achieve the requirement.
Regards
Ravinder.s

Hi,
In the SOAP Receiver adapter, you can only store 10 userid/password combinations via Authorization Keys. These are called via Dynamic Configuration via technical name TAuthKey. In your case, for it to work, you need:
1. 2 business components/2 SOAP receiver communication channels.
2. 1 receiver determination with xPath for username to determine correct business component
3. 1 interface determination
4. 2 receiver agreements (one for each cc)
Hope this helps,
Mark

Can I hook up a NAS via Fibre Channel?

I am building a Linux NAS to be accessed by my Macs. I've purchased fibre cards for all of my macs, an LSI fibre card for my Linux machine, and a McData 4400 fibre switch. I'm trying to configure my fibre network so I can share files from my NAS. I've got the fabric set up, but everything that I read is talking about using SAN software to connect to a SAN, not a NAS. I can't find any information at all on how to do what I want to do, or whether or not it's possible. Can someone please help me figure out how to set up this Fibre Channel network, or at least figure out if it's possible or not? Thank you!
-Ryan

Is what you want technically possible? Probably.
In an earlier era, you could have a network or an image scanner or other devices connected to a host via SCSI; via a storage bus. There was all manner of odd SCSI-connected gear. (Think of SCSI as expensive multi-host USB with big expensive cables and with expensive peripheral devices, and you'll have the general idea. And FWIW, SCSI is the underpinnings of USB.)
You would end up writing a whole lot of driver code for the devices and hosts you have, too.
Which is where folks end up with commercial SAN solutions, or with NAS solutions, and not with using a SAN as a network.
The various Fibre Channel controller vendors discussed but never seemed to have sorted out the network interface designs for their FC controllers.
If you want to roll your own storage arrays akin to the [Apple Xsan|http://www.apple.com/xsan> or the HP [MSA|http://h18000.www1.hp.com/storage/diskstorage/msa_diskarrays/sanarrays/index.html] or [EVA|http://h18000.www1.hp.com/storage/diskstorage/eva_diskarrays/evaarrays/index.html] SAN arrays, well, have at. You'll likely end up needing to write host disk drivers, as well as the firmware within the SAN controller. Networking drivers might be a bit more tricky; I haven't looked at those device interfaces in a while, and you'd need to tie those drivers into the host network stacks. Once you have some or all of that working, then the hosts can see the block storage out on the SAN. If you need sharing, you'll need to sort out a cluster or SAN file system to run atop the block storage or atop the network connection you've built; a file system that can coordinate distributed access.
Possible? Sure. On a budget? Probably not.

Need docs that explain Fibre Channel setup, getting I/O error on 2540 SAN

Sun T5220 Host running Solaris 10 5/09 as management host.
Qlogic 5602 FC Switch
Sun Storagetek 2540 - one controller tray with 9 300G SAS Hitachi drives. Firmware 7.35.x.
Sun branded Qlogic QLE2462 HBAs - PCI express, dual port. 3 in the T5220. qlcxxxx drivers for the HBAs.
Sun Common Array Manager software version 6.5.
I am a long-time Oracle DBA who has the task of setting up a Fibre Channel SAN. I am not a Solaris sysadmin, but have installed and maintained large databases on Solaris boxes where I had access to a competent sysadmin. I am at a classified site and cannot bring out electronic files with logs, configuration info, etc. to upload. Connecting the T5220 is the 1st box of many. This is my first exposure to HBA's, Fibre Channel, and SAN, so everything I know about it I have read in a manual or from a post somewhere. I understand the big picture and I have the SAN configured with 2 storage pools each with 1 volume in them on RAID5 virtual disks. I can see the LUN 0 on the T5220 server when I do a luxadm probe and when I do a format. I formatted one of the volumes successfully. Now I attempt to issue:
newfs /dev/rdsk/device_name_from_output_of_luxadm_probe
I get an immediate I/O error. I could be doing something totally naive or have a larger problem - this is where I get lost and the documentation becomes less detailed.
What would be great is if anyone knows of a detailed writeup that would match what I'm doing or a good off-the-shelf textbook that covers all of this or anything close. I continue to search for something to bridge my lack of knowledge in this area. I am unclear about the initiators and targets beyond the fundamental definitions. I have used the CAM 6.5 software to define the initiators that it discovered. I have mapped the Sun host into a host group also. I do not know what role the Qlogic 5602 Fibre Channel switch plays with respect to initiators and targets or if it has any role at all. Is it just a "pass through" and the ports on the 5602 do not have to be included? Maybe I don't have the SAN volume available in read/write. I find bits and pieces in blogs and forums, but nothing that puts it all together. I also find that many of the notes on the web are not accurate.
This all may appear simplistic to someone who works with it a lot and if you know of an obvious reference I should be using, a link or reply would be greatly appreciated as I continue to Google for information.

Thanks for the reply. I had previously read the CAM 6.5 manual and have all the SAN configuration and mappings. Yesterday I was back at the site and was able to place a UFS filesystem on the exposed SAN LUN which was 0. I've not seen any reference to LUN 0 being a placeholder for the 2540 setup and when I assigned it, I allowed the CAM 6.5 software to choose "Next Available" LUN and it chose 0. LUN 31 on the 2540 is the "Access" LUN that is assigned automatically - perhaps it is taking the place of what you describe as the LUN 0 placeholder.
I was able to put a new UFS filesystem on LUN 0 (newfs), mount it, and copy data to it. The disk naming convention that Solaris shows for the SAN disks is pretty wild and I usually have to reference a Solaris book on the standard scsi disk name formats. My question/confusion at the moment is that I have 3 Sun branded Qlogic HBA's in the Sun T5220 server - QLE2462 (dual port) with one port on two of the HBAs cabled to the Qlogic 5602 FC switch which is cabled to the A and B controller of the SAN 2540 - there are only 2 cables coming out of the 5220; the 3rd HBA (for future use) has no cables to it. Both ports show up as active and connected on the server down to the SAN and the CAM 6.5 software automatically identified both initiators (ports) on the Sun 5220 when I mapped them. I had previously mapped them to the Sun host, mapped the host to a host_group, virtual disks to volumes, volumes to....etc.; and was able to put data on the exposed volume named dev_vol1 which is a RAID5 virtual disk on the SAN.
When I use the format command on Solaris, it shows two disks and I assumed this represented the two ports from the same host 5220. I was able to put a label on one of these disks (dev_vol1), format it, and put data on it as noted above. When I select the other disk in the format menu, it is not formatted, won't allow me to put a label on it (I/O error) and I can go no further from there. The CAM 6.5 docs stop after they get you through the mapping and getting a LUN exposed. I continue on the in a Solaris-centric mindset and try to do the normal label, format, newfs, mount routine and it works for the one "disk" that format finds but not for the other. The information from the format info on both the disks shows them as 1.09 TB and that is the only volume mapped right now from the SAN so I know it is the same SAN volume. It does not make sense that I would label it and format it again anyway, but is this what I am supposed to see - two disks (because of 2 ports?) and the ability to access it through one. I found out by trial an error that I could label, format, and access the one. I did not do it from knowledge or looking at the information presented....I just guessed through it.
I have not "bound" the 2 or HBAs in any way and that is on my list as next because I want to do multipathing and failover - just starting to read that so I may be using the wrong language. But I am wondering before I go on to that, if I am leaving something undone in the configuration that is going to hamper my success in the multipathing - since I cannot do anything with the 2nd "disk" that has been exposed to Solaris from the SAN. I thought, after I labeled, formatted and put a filesystem on the one "disk" I can write to that the other "disk" that shows up would just be another path to the same data via a 2nd initiator. Just writing that does not sound right, but I am trying to convey my thoughts as to what I logically expected to see. Maybe the question should be why am I seeing that 2nd "disk" in a Solaris format listing at all? I have not rebooted any time during this process also and can easily do that and will today.

OSX 10.5.6 doesn't see Fibre Channel Disk array, neither does Disk Utility

My system is a Power Mac G5 Quad, 6gb Ram, 1Tb internal hard drives, 1Tb external and several portable drives as needed.
The Drive array in question is a Fujitsu GR710 which contains 12 Seagate Cheeta ST336605FC drives which are around 35gb each.
OK, I have been given a Fibre Channel system, that at one time worked with OSX. I had to move it and now it doesn't show up on Disk Utility anymore. I can totally reformat it if possible, but I have to be able to see it first.

Hardware RAID says that there is no hardware present.
I am using the Apple MA900A/G Fibre Channel Card to hook into the Drive array. It is hooked up with both ethernet and fiber optic cables.
I have used an IP scanner to search for the IP of the array and only find one that I can't identify at 224.0.0.251 another scan reports an IP of 0.0.0.0, neither worked when I tried to use Safari to access it.
I have tried several programs to try and get into this array and nothing sees it. All my experts tell me that I will need to use the Terminal program and use command lines to access the drives, but I can't find any information about what to do there. I've been told I need the driver for the array, naturally there isn't a driver for Mac to be had, but there are drivers for solaris, Unix, and windows. The last expert said to use the Unix driver, but I don't know where to put it in the system.
So I need help, Terminal commands to talk to the drive and revive it hopefully, or a system program that will do something similar. None of my diagnostic programs sees the array. The Card came with no software or instructions. Neither did the array. I haven't been able to find any hardware information about the drive from FuJitsu at all, it's too old for them to bother with anymore.
Any help would be greatly appreciated!
Thanks
Doc

I have to go with William on this one - if it's shows up over fibre then it should be okay. Have you gotten the admin module to see the device over ether? I have a feeling that is you can get the software to see it you might be able to configure the device into something the computer could mount.
The Promise that way - you can configure the device entire from the web interface and you don't need fibre communication working for any of the configuration of what RAID you want and which disks are attached with what set etc. Once the RAIDs are configured into volumes then the Xserve sees they exist and you can use Disk Utility to format them. If you don't need fibre communication I don't see how SCSI drivers would matter over ethernet. But maybe the box is a strange beast - odder things have been made.
Barring that - can you attach the device to an older machine with the drivers and configure the device into raw volumes and then an HFS+ (or whatever you want) system? If you did that and then switched the box back to Xserve it should be able to pick up the configured volumes drivers or no.

Xserve, G5, Xserve RAID and fibre channel question

hi guys,
I have a Xserve conneted to Xserve RAID right now. Is it possible connect G5 to Xserve RAID thru fibre channel ? thanks

>is it possible to do ?
Not in the way you describe, no.
The XServe RAID's 14 drives are connected to two separate controllers. Drives 1-7 are connected to the upper controller. Drives 8-14 are connected to the lower one.
If your XServe is currently connected to the upper controller it's talking to drives 1-7.
If you connect the G5 to the lower controller it will be talking to drives 8-14.
Therefore you cannot use this setup to backup the data via the G5.
At the very, very least you need a fiber channel switch so that both the XServe and the G5 can connect to the same controller. However, as Tod has already mentioned, it is tricky to get multiple machines talking to the same RAID drives while avoiding corruption (there's no concept of arbitration, or ways of preventing one machine from editing a file that's in use by the other machine).
You have two basic options - one is to implement XSAN, which will handle the arbitration issue, the other is to configure the G5 to mount the RAID read-only. This should prevent the G5 from modifying a file while it's in use by the XServe (which may be sufficient for backup purposes), but you may still run into issues when the G5 tries to backup a file that's actively in use by the XServe.
In all honesty, a better solution would either to get a SCSI card that works with the XServe and do it all there, or use file sharing between the XServe and the G5 and backup over the network - it'll be slower, but a lot more reliable.
