Iscsi storage - appliance ports on FI or core?

i got some 10gb iscsi storage (nimble storage) that i would like to presebt to the ucs esx blades.
should they be configured as appliance ports on the FI or should i put them on the 7k core?

both configurations are possible.
If this iscsi box is a shared storage device, e.g. for other UCS domains, and/or non UCS servers, connection to the N7k is the preferred setup.
If this is mainly a test or a SMB environment, direct attachment via appliance port is possible.

UCS FI and iSCSI Storage

We're getting ready to implement a UCS B Series. I have a question about the 6248UP FI. I've read and used the emulator for UCS Manager and noticed you can configure FI ports as Appliance ports for storage. Is this limited to a certain storage protocol or vendor? We use Dell EQ and plan to connect the EQ 6510X to it. Just wondering if that is supported and if upstream iSCSI traffic would be able to access the storage?
The 6248UPs will be uplinked to a pair of Catalyst 4506-E running VSS. We have a IBM blade chassis and the servers would need to be able to access the EQ6510X too. I'm assuming i just need to trunk the iSCSI VLAN to the 6248UP and the servers would have access?
Thanks!

Hi Cowetac,
Yes, not all storage arrays are supported by UCS, but your DELL Equalogic is supported. If you have any questions about other storage arrays compatibility, you can take a look at the UCS Storage Interoperability Matrix (See Link Below).
UCS Storage Interoperability Matrix (Table 10-2     UCS-B Storage Support Matrix)
http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix8.html
I'm assuming i just need to trunk the iSCSI VLAN to the 6248UP and the servers would have access?
Depends, if you are going to use t an appliance port on UCS to connect directly to the storage, you can only use a single vlan.
if you are connecting via the Ethernet uplinks through a switch, then you would have to set your switchs port as a trunk.

Can Appliance port be a FCoE target?

Hi,
Some how i got the feeling that to an Appliance port only a iSCSI target can be connected. I may be wrong. If i am i want the experts to clarify. To me it appears that, UCS FI, can not work as FCF that Nexux 5000 is capable of. If it is not capable of doing FCF function it would always need a upstream to an Nexus 5000 switch ? These things are not very clear on the user guide. I hope the docs gets better in coming days.
Regarding configration of appliance port, i have another question.
During configuration, one step is to assign a mac-address to the appliance port. What is this mac-address? Is it Target port that we are going to connect to mac-address, is it the switch interface mac-address which is it?
cisco-A-A /eth-storage/fabric # scope interface 1 7
cisco-A-A /eth-storage/fabric/interface # create eth-target macname
cisco-A-A /eth-storage/fabric/interface/eth-target* # set macaddress 18:10:10:6f:d2:03
cisco-A-A /eth-storage/fabric/interface/eth-target* # commit-buffer
If i look at the interface detail it shows,
cisco-A-A /eth-storage/fabric # show interface 1 7 detail
Storage Ethernet Interface:
    Slot Id: 1
    Port Id: 7

I connected FCoE target to this port. I dont know where to look for if the target has logged into the switch. Also how can we verify the LLDP negotiations?
Appreciate your response.

Well I have finally managed to get my FCoE target logged into the UCS Inteconnect.
It is through FCoE storage port. Have to configure the ethernet interface port as FCoE storage port. I was not successful when configured as appliance port.
Here are my flogi database from FCoE login,
cisco-A-A(nxos)# show flogi database
INTERFACE        VSAN    FCID           PORT NAME               NODE NAME
vfc757           1025 0xee0000 20:00:00:10:18:6f:d2:03 10:00:00:10:18:6f:d2:03

Total number of flogi = 2.

CD-ROM drive letter changed to the next available letter after an issue with the Storage appliance.

Server platform:Windows server 2008 R2 Enterprise.
Last time we experienced an issue with the storage device we are using to attach a disk to our server 2008 (virtual). This storage device is also providing storage to the ESX where the server 2008 is hosted.
The drive configuration in the server was:
System C:\
Tools D:\
Apps E:\
CD-ROM F:\
Some hours after the storage appliance issue, we realized the Application on the server was not working and then we restarted the server. After restarting the server we went to the file explorer and realized that the Apps volume had the drive letter F and
the CD-ROM had the E letter assigned.
I assume windows lost the Apps disk due to the SAN disconnection. Maybe the CD-ROM was also disconnected and when the Storage appliance was connected again the CD-ROM acquire the next drive letter it found, which was the letter E:. Then the Apps disk was
also discovered by Windows and it assigned the next available letter, F:.
I was looking for some MS knowledge base to see how Windows 2008 server assigns the letter to the CD-ROM and how we can permanently fix the letter assigned to the disks and the CD-ROM so that this issue won't happen again. As you know many applications use
the path including the drive letter.
I thought that when you set a CD-ROM drive letter, it remains forever as is, and that in case of a SAN disconnection Windows assigns the same letter the drive had before the disconnection.
Please advice if you have some documentation about this. And let me know if you have any thoughts about what really happened to prevent this in the future.
Thank you guys!!

Hi, for the APP's drive it could had been assigned a new letter if the system did seen it as a new disk/partition.
The partition was on your esx's LUN on the SAN ? (not an iSCSI connection from inside a VM?)

Texas RamSan Solid State Storage Appliance and Oracle VM 3.x

Has anyone had success with using a Texas Memory System RamSAN 810 (solid state appliance) and Fiber Channel controllers with Oracle VM 3.x
I believe any Fiber Channel device should work as shared storage, but looking for some extra confirmation that there were no issues before actually buying.
Thanks for any information.

In playing with OVM 3.0 so far, I see that local storage (as the accelerator cards would show up as) is not really appropriate for Production Systems. It appears I can create a Repository on these physical disks and then present them to the VM guest. Then add these cards as my Oracle ASM disks for my "fast" storage, and do the same with the FiberChannel storage for my "slower" disks. Because of the Local Storage used for part of the VM guest, we would not be able to Live Migrate or have High availability I believe. Is this correct? Correct.
If we have the two servers as mentioned above. Could I take the database VM down and move it to the other server (ie Cold Migration)? The local storage (ie the accelerator cards) could physically be moved from one physical host to the other, but I am not sure, since this is virtualized disk, if this would be allowed or how it could be recognized on the other Oracle VM Server. This might be a "dream", but might be something we would like to do if an emergency arose or if more maintenance needed to be done on Server 1. Any comments?You would have to shutdown the VM, migrate it to an unassigned folder, edit the VM, remove the local storage from Server 1, migrate to Server 2 and add the local storage from Server 2. Whether or not this means moving your hardware is up to you.
Does anyone have other solutions to run Solid State disks (approximately 2TB worth) and Oracle VM, running a single guest that runs the database? We have been unable to find iSCSI or FiberChannel enclosures that can handle solid state drives in the 1 to 2 TB range of capacity. So perhaps there are other enclosures out there that can act as Shared Storage that can operate with SSDs. Thank you for any comments and suggestions.I know the Sun storage appliances use hybrid storage, i.e. a mix of SSD/spinning disks, but I don't know the details. Our Exadata machines have 5TB of Flash storage per cell, so I know we have such options.

Appliance port on 6248 Fabric Interconnects

Is it possible to setup a storage device with a CIFS share on the 6248's through a port defined as an appliance port? The GUI guide says this:
"Appliance ports are only used to connect fabric interconnects to directly attached NFS storage."
But what would be the difference if it were a CIFS share rather than an NFS mount?
I'm trying to setup a storage unit that does both NFS and CIFS, but the backup software that I want to point to it through the FI's needs to have it as a CIFS share due to being a Windows platform.
Any and all comments welcome.
Thanks,
Chad

iSCSI, CIFS and NFS targets are all valid uses for the appliance port.
All the appliance port does is allow MAC learning on the interface.

Robert

How to change the SystemID (system name) of the HP StoreOnce Virtual Storage Appliance (VSA)

I can't seem to find a darned way to post a question regarding the HP StoreOnce Virtual Storage Appliance. I want to change the name (SystemID) of a StoreOnce VSA that has already been deployed. The web interface has NO way of changing any value.
The command line interface (through ssh) doesn't seem to have any way to change the SystemID value in any way. I want to change this value so that when I have it join the Active Directory domain it is a meaningful name, and NOT the serial number of the VSA.
I KNOW that I am asking in the wrong place, but I don't know what the proper place is to ask this question.
Unless you have either of the below keep your comments to yourself:
1) a real suggestion on where to post this

Using Appliance Ports for NAS

Using Appliance Ports for NAS
Hey all connecting a NAS to UCS. Would like to plug in directly to FI’s using the Appliance Port option.
Are the steps basically
Turn on Ports use as Appliance Ports
Make PIN Group through Appliance Ports (this will only be one port per FI, I am guess Port-Channels can be used if NAS supports that?)
Make VLAN internal to UCS
Make vNIC Template and use newly created VLAN and PIN Group
Boom!
Right?
Thanks!
Craig

I have made port 20 on each 6120 an Appliance Ports.
Each port is assigned to a VLAN made under the Appliances tab.
Cannot seem to make a PIN group using these Appliance ports. They are not a option.
Is there something I am missing?
Thanks!

Windows 2008 R2 cluster with iSCSI storage.

We have a 2 node cluster setup with iSCSI storage. Is there a way to set the storage so that it becomes active on a specific node, when that node is online? The storage is failing over properly but we have to do a manual failover to get the
server back on the "primary" node.

DNFS and ZFS Storage Appliance: What are the benefits and drawbacks

Hello All:
I have a client who has a 4TB database and wants to easily make clones for their DEV environment. The conventional methods (RMAN duplicate) are taking too long because of the size of the db. Looking into dNFS as an alternative standalone and looking into the ZFS storage appliance as well. What are the benefits of just dNFS being configured alone? I'm sure you can clone easily based on the copy-on-write capabilities but weighing the dNFS option alone (no additional costs) vs using ZFS Storage Appliance (which used dNFS as its protocol) but costs money. Your thoughts?

Dear Kirkladb,
as far as I understand your question you like to know the road blocks for usage of dNFS in combination with a ZFS Storage Appliance.
First I like to mention that dNFS is no feature on the appliance and the dNFS traffic is perceived as regular NFS traffic, so there is currently no feature which needs extra licenses on the ZFS Storage Appliance if you run dNFS on your client; dNFS is client driven and requires software on the client. Second the use of dNFS does not exclude to have snapshots or clones on the appliance, although cloning requires a license to be bought.
As mentioned by Nitin the appliance offers many features, some are based on ZFS, some are coming for the underlying OS and some coming form additional software. You seem to be interested in NFS, this is I guess mainly related to NFSv3 and NFSv4. The appliance will see dNFS from the clients as regular incoming NFS requests, means client side makes the difference and therefore it is important to have dNFS and maybe Infiniband drivers at a current level.
To get a copy of your production Database you could go different ways, the appliance offers to create a snapshot (free of charge) which is read-only and to create a clone (additional costs) on top of the snapshot. You have mentioned RMAN, as additional method, Snap Management Utility (Clone License) will also help here and maybe DataGuard. I am sure there are some additional ways not listed.
The point I wanted to make is that Cloning on ZFS-SA abd NFS are different are topics.

Hi,
There are 2 steps you need to do - move DPM server and move data.
For move DPM server, you need to backup DPM database and restore in new server. Please see steps in following article:

ISCSI storage with UCS

Hi All,
Can i ask a question with regards to connecting iSCSI storage to use with UCS. We are looking at using Nimble storage which is iSCSI based & want to understand best practise recommendations on how to connect it to UCS to get the best level of performance & reliability/ resilience etc.
Another question is more around how VMware deals with loss of connectivity to one path (where dual connections are setup, from storage to fabrics), would it re-route traffic to running path?
Any suggestions would be appreciated.

Hello Kassim,
Currently Nimble iSCSI storage is certified with UCS 2.0.3 firmware version.
