• UCS FI and iSCSI storage

  We are poised to implement a UCS B Series. I have a question for FI 6248UP. I have read and used the emulator for UCS Manager and noticed that you can configure ports FI as ways for storage material. Is it limited to a certain protocol storage or the seller? We use Dell EQ and plan to be there to connect the EQ 6510 X. I was wondering if that is supported and if iSCSI upstream traffic would be able to access the storage?

  The 6248UPs will be passed to a pair of Catalyst 4506-E race vs. We have an IBM chassis and servers should be able to access the EQ6510X too. I guess I just need master iSCSI VLANS for the 6248UP and the servers would have access?

  Thank you!

  Hi Cowetac,

  Yes, not all storage arrays are supported by UCS, but your DELL Equalogic is supported. If you have any questions about the other compatibility of storage arrays, you can take a look at the UCS (see link below) storage interoperability matrix.

  UCS storage interoperability Matrix (matrix of the storage of UCS - B of table 10-2)

  http://www.Cisco.com/en/us/docs/switches/Datacenter/MDS9000/interoperability/matrix/Matrix8.html

  I guess I just need master iSCSI VLANS for the 6248UP and the servers would have access?

  Depends, if you use one port of the device the UCS for you connect directly to storage, you can use a single vlan.

  If you are connected via the Ethernet uplinks via a switch, you need to set your switches as a trunk port.

• Connect FI two directly attach FCoE storage and SAN switches

  Nobody tells me if I can connect FI two directly attach FCoE and SAN storage switches also, as you can see in the diagram of connected network?

  If so, should I FC Switch function Mode? Any concerns should I consider?

  Or the best solution would be appreciated. Thanks in advance.

  The UCS will be in Switch Mode FC, which means that it has a default area.  We cannot make a Zone merge with Brocade because we have no control to set up specific items such as domain and other articles CF IDS that need to be changed when you connect a Cisco FC switch to a Brocade.

  Usually in this situation with a 5 k or a MDS you might be placed in mode of interoperability, which changes the default settings and we will talk to them together - in this case, you can't change these settings, so the only supported configuration is CF Cisco at Cisco.

  See you soon,.

• MSA 2040 Direct attached iSCSI

  We implement a VSphere environment 5.5-3 hosts directly connected to an MSA 2040 with iSCSI.  Attached host to the MSA a question directly or have us use switches?  Our equipment provider said

  "in order for the volumes of VMWare to have access through shared storage needs through a switch. You can run questions where if they are directly attached, then the VMDK on the single host may not be seen or accessible on other hosts (high availability or Vmotion). »

  Also

  "Support from direct attach to the msa via iSCSI is dependent on the BONE."  Some OS support other don't. MSA does not directly connect to Vmware via iSCSI. "

  I talked to HP directly and they claim to direct connection via iSCSI is supported with the MSA 2040 and VMware.

  Is anyone running this configuration that can put my mind at ease?

  Thank you.

  Hello

  Yes, you can use a directly attached MSA 2040.

  I use this configuration yourself by using DAC 10 GB cables, also sold this solution to customers.

  Please note that each host must have 2 connections to the San (if the SAN has two controllers). Each host must have a connection to each controller on the SAN.

  4 directly attached hosts is supported (the controllers have 4 ports on each one).

  Please note that several subnets must be used and configured to allow a correct path discovery. A BIG note to stress also is DO NOT USE the PORT iSCSI MAPPING!

  Be sure to activate the Robin. Please note that you will see an active path perform I/O by the data store (since only one controller has a volume), but in case of rupture of the cable, or controller failure, there are switched to the other controller.

  I use this setup for a few years and I love it!

• Problem when adding 2nd host in Iscsi storage shared

  Hello people.

  I'll try to explain exactly my problem even if it is a little difficult liitle!

  First of all, we are talking about a test environment that is installed in my house just for learning purposes.

  I am facing a strange my iscsi storage behavior when trying to join a second host to storage vmotion purposes. I was using an Esx host (3.5) for a while and I had no problem with the iscsi storage (I use an old pc with freenas on it). I must say that I got lucky, also, local sata controllers have been recognized so I could test the Storage Vmotion between two storages (Commons and iscsi) with success in this host.

  To continue to learn, I decided to also buy another pc to test Ha cluster, Vmotion, DRS. Unfortunately, I couldn't find the same material and who as well as sata controllers do not to be recognized, so I used a disk ata for OS and my intention was to use for the volume vmfs3 iscsi storage.

  In the first host esx I used, you can see 3 storage adapters: vmhba32 vmhba33& gt; Controllers local sata,34vmhba& gt; initiator iscsi software

  In the second esx host, you can see only the vmhba32- & gt; the iSCSI Software initiator.

  The first time everything worked ok, which means that I have attached iscsi storage in host the2nd by rescaning the vmhba and I was able to browse the datstore and see the contents of it, but it lasted only 10 minutes. Then suddenly I lost the connection to common storage to both hosts, I could see in the section maps of storage, but when I pressed update in the storage section, nothing happened and even when I tried to add it using the add storage I received the message usual "cannot read the partition table information. After being a little more careful I noticed that in the section storage cards, I could see the same vmhba34 in the two hosts with the same alias to the host of the first, and here's the strangest part, the situation I described above has been changing from time to time, which means that a few times I have seen the vmhba32 in both hosts and after some time vmhba34 in both hosts! (crazy)

  I took the big decision after playing with the partition table, without effect to use the ' vmkfstool - C vmfs3 s ' _free "_ / vmfs/devices/disks/vmhba32: 0:0:1" command

  in the second host, of course, I lost all data, but now with a simple refresh in this host, I was able to see the storage.

  Unfortunately, I still couldn't ' 1 host storage access and I published the same command "vmkfstool - C vmfs3 s"free"" / vmfs/devices/disks/vmhba34: 0:0:1 ""

  with only the change you see in bold. Accordingly, it was to see the storage after a refresh with free (1) name.

  Now he is currently working for 2 days with this way not recommended and what I would be really grateful if could help me clarify what exactly is happening.

  My main problem is that I am in front of a very unstable environment that might as well have the same unexpected problem in the future and I can't reformat always storage and loss of all virtual machines

  I tried to describe the best I could to this strange situation!

  Thank you for your time and any help or advice would be most welcome!

  I was looking for a similar solution. Seems to be the only iSCSI host is possible on freeNas. See here: http://apps.sourceforge.net/phpbb/freenas/viewtopic.php?f=53&t=403&sid=f4881e6e25e752e6ee8c6b0eae5887d3

  The only solution for learning seems to be to install the server ESX or ESXi in a virtual machine and then use iSCSI. Vm Instructions to complete the installation here (you must all PDFs 6) http://knowledge.xtravirt.com/white-papers/esx-3x.html or you can replace the opnefiler by the SUN's VM iSCSI. http://www.sun.com/storage/disk_systems/unified_storage/resources.jsp , you must use the vmware converter to convert the SUN's virtual to be used in ESX machine found this in a forum... but can not find more URL. I have not tried myself but, looking for just because you want to get a similar setup.

• subnet VMkernel iSCSI for direct-attached storage

  Hello

  I have two hosts esxi 6.0 that I connect to a shared via iSCSI storage. I followed this document technical http://www.vmware.com/files/pdf/techpaper/vmware-multipathing-configuration-software-iSCSI-port-binding.pdf#sthash.7bztDoAS.dpf to configure interfaces iSCSI on the esxi with binding ports host. No problem.

  I use HP MSA 2040 with a dual controller and I'll connect two hosts directly on the shared storage. As for the hardware, according to the documents on best practices, it is recommended to follow a vertical subneting for ports of controllers. However, I have not found no requirement for iSCSI ports in vmware, all of the examples I found configure each vmkernel port in a different subnet, as I did:

  vSwitch0

  iSCSI1 - vmk2 - 192.168.1.11 (unused vmk3)

  iSCSI2 - vmk3 - 192.168.2.11 (unused vmk2)

  So, my question is vmkernel ports are in different subnets? or could they be in the same subnet with no difference performance wise?

  Any help would be appreciated.

  Thank you!

  in your case, because you are trying to achieve Multipathing to iSCSI Software initiator, the vmkernel ports should be in the same subnet.

• Deliver the addition of iSCSI storage visible via vSphere (direct host or vCenter)

  Hi all

  I'm having a strange problem when I try and add a second drive to my host ESX 4.1. The storage is visible, but when I go to add it via the add storage wizard I get the following error message:

  Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" of object "ha-datastoresystem" on ESX '172.16.10.221' failed.

  As shown below:

  

  

  The error is the same weather, I try to add via vSphere connected to vCenter or ESX 4.1 host directly.

  The funny thing is that I have a small iSCSI target on the same iSCSI storage that works very well.

  Here is my config network:

  

  And here is my config to storage adapter:

  

  I have also attached my vmkiscsid.log of the esx host file.

  I think what's happeneing, is that the ESX host tries to enter and format the storage via the console port of service instead of the iSCSI port I created but I could be wrong.

  Any help would be greatly appreciated!

  Thank you.

  Pell Manny.

  Size of the disk (including the iSCSI LUN) is still limited to 2 TB minues 512 b... Try to drop the size of the iSCSI LUN down that maximum and try again... I would bet that the 'small' target that you have not had any problems with less than this limit is...

• Connection Cisco UCS 6120 FI directly to Cisco Catalyst 6500?

  I watch a lot of design with the Cisco UCS solution guide and everywhere it is Cisco Nexus 5000/7000 connects to the uplink ports of Cisco UCS 6120 FI with the benefits of technology to the vPC.

  How about connect Cisco UCS 6120 FI directly to 10GE ports in Cisco Catalyst 6500 (without VSS and VSS)? It is possible to design?

  If I use C6500VSS there will be port-channel of the aggregation of the UCS Nx10GE all the bandwidth?

  And what happens if I use C6500 (without VSS) - how it will be on the many links between UCS and two boxes C6500? It will be blocked by STP? A little on the other?

  Please explain to me, because we have only C6500 switches in our data center and want to test a Cisco UCS schassis.

  Yes, you can connect the 6120 s to cat6500s with or without vs. With VSS, you get a vPC as port channel where 2 links to a single 6120 can be connected to different 2 6500 s in a port LACP-channel.

  VSS is not necessary, you can connect a 10 G uplinks / 1 G of 1 or more of a 6120 at cat6500s. I you have 2 cat6500s (non - vss) and 2 uplinks by 6120, then you want to connect 1 cat6500-1 and the other to cat6500-2. I would recommend going ahead and creating a single port-channel port so that you can easily add the uplinks in the furture without interruption of service.

  Ideally, for non - vss, I would have 4 10 uplinks by 6120; 2 in a channel port cat6500-1 and 2 in a port in cat6500-2 channel

• Configuring the Cisco UCS 5108 ports

  Hi all

  I'm new in the world of the Cisco UCS server and am setting up Cisco UCS 5108 blade server. The server has two Cisco UCS 6324 interconnections fabric I did the initial Setup on and I try to configure the ports for the blades. Looking through the various articles and tutorials after setting global policies, I see the whole world establishment of uplink and server ports. What I read the uplink ports are plugged directly into the switches (I work with two cisco nexus switches), and server ports are used to connect to the chassis.

  I wonder once the configured ports server what exactly are supposed to connect to? I assumed they would also connect to the switch nexus with the uplink ports. However, every time I set up the server ports and plug them in, the switch doesn't seem to have flooded and we lose all connectivity. If I unplug, the connection is restored almost immediately.

  The current configuration, that I work with is two ports uplink on each fabric interconnect (4 2 total in each switch of nexus), two server ports on each (4 2 total, in every nexus switch). The only other element connected to the nexus switches is a SAINT who will be configured as a boot and storage of the UCS 5108.

  Looks like you have a Mini UCS (6324), with 4-port 10 GB (each FI/IOM) with port QSFP 40 GB that can provide network connectivity linking rising, or if configured as a server port, could be used to connect to a server in a rack compatible Cisco UCS, or connect to a 5108 additional with IOM 2204XP chassis.  The blades installed in your initial 5108 chassis 6324 FI/IOM of housing have internal connectivity to the FIs / IOM without the need to configure ports 'server'...

  Please take a look at some of the visuals in the datasheet below.

  http://www.Cisco.com/c/en/us/products/collateral/servers-unified-computing/UCS-6300-series-fabric-interconnects/datasheet-C78-732207.html

  Unified ports can also be configured as a FC ports for connectivity of FC switch upstream or directly related to CF Storage processors.

  After having watched the datasheet, let me know if you have any other questions, and I'll try to address them.

  You'll not need actually configure ports such as ports 'server' unless you connect servers in a rack.

  Please configure any ethernet SFP type connected to your switches nexus upstream as 'network' uplinks.  I guess that you don't plan on a disjoint config layer 2 (where each FI has several sets of uplinks will different devices upstream, or the same device with different VLANS allowed on each link).    If you are, we can have a separate thread about how you need to configure that.

  Thank you

• Mellanox for Cisco UCS RDMA support.

  Hello

  I wonder if anyone can help or tell me if there is interconnection support RDMA Mellanox and Cisco UCS B series or fabric. It is possible to connect on the technical level.

  I have clients who have Cisco UCS B Series more Windows 2012 R2 HyperV installed, who now want to connect RDMA Mellanox storage medium

  Hi murielle

  Important caveat: RoCE means RDMA over converged Ethernet.

  If you look at the YouTube mentioned above, you will see, that SMB Server and Client on the blades of the UCS; so no interop Situation. everything happens within a domain of UCS.

  In your situation, you have a comprehensive Converged Ethernet network (Cisco and Mellanox); your customers could be on the blades, the servers attached to the Mellanox switches.

  It is essentially a question Interop; I have no idea if it has been tested or not.

• Service profile of the CISCO UCS for ESXi

  Do you need multiple boot LUN on the storage array for each host that you want to apply the service profile to? I'm just confused, let's say I have 12 blades that I want to designate as boot SAN for ESXi, y aura-t 12 profiles of separate service for each of them, and will need me 12 different LUNS on our storage? I am new to this and I just want to make it as clean as possible! Any help is appreciated.

  Hi Justin,

  You can have the same LUN ID for multiple service profiles, as well as the same target ID. However, your initiators will be different and you will need to configure the zoning on your switch upstream if you use the end host mode.

  Here is a good guide, review the basics and how to put in place.
