UCS/Nexus and FCoE Question

Hi all:

Can we connect a FCoE target directly to an interconnection of fabric or a Nexus 5xxx CWF in NPV mode and not connected to an FC switch for power and tissue services continue to have the initiator see the target and be able to supply storage as a result?

Thus, the scenario would be the following:

a server rack with an ANC connected to a Nexus 5xxx CWF in NPV mode

OR

a server blade a NON related to interconnection of UCS fabric (which is also a CWF) in VAN mode

AND

In the above cases, there is NO CONNECTION between the RTC and an FC switch.

I will be able to have the ANC (FCoE initiator) see table of Strorage (FCoE target)?

Thank you

Hello

Yes you are right. For the direct-attached storage work, you need the FI in FC switch mode. Your explanation is good and you can not storage direct-attached mode/npv end FC host mode. With FI in npv mode, it can just transfer CF applications to an NPIV switch and cannot process any request CF as FLOGI etc...

In addition, in the UCS versions under 2.1 you need a SAN switch connected to a FI running in mode switching and storage directly connected to it, which can push the FI database zoning. Thanks to 2.1, you can have storage direct-attached without the need for any SAN switch upstream as we have zoning capabilities in UCS now.

In short, for all direct-attached storage, you must have FI FC Switching mode.

  • Setting port channel between UCS - FI and MDS 9124 (Mode F)

    Dear team,

    We tried to create the channel of port between UCS FI and MDS 9124

    But the port channel do not take action in mode F on MDS 9124

    FI is in host FC end Mode

    We have allowed FC uplink on FI trunking

    We have activated NPIV on MDS

    We have activated the MDS trunk

    FI and MDS in default VSAN

    To check that we have changed the way FI FC channels mode and switch port became active, but in E mode

    When we enabled CF trunking of uplink on the port mode FI channels and FC Switching became active in mode TE

    What version of the software if your MDS race?

    On your UCS do connect nxos and show ficelleStringString ficelleT inteface and find the mac address.

    It is possible that you could be hitting the bug below. If this is the case, you may need to update the firmware on your MDS.

  • 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.

    Anything can be corrupted on your MacBook Pro, but from what you say, it seems that the cable drive/SSD/flash memory/SATA hard was seriously damaged. Him "question mark" means that your Mac is unable to find any bootable device, meaning that it does not yet detect your OS X drive.

    You should make a backup of your files (if you can still do it) and take the Mac at the Apple Store or dealer to get a diagnosis. There may be several damaged parts.

  • WinXPsysytem: The upgrade and have questions

    Have a dell e521 that I train and some questions.  Have already updated to 3 GB of memory on x 86 operating system.  Bios version active what 1.1.6 4/7/2007.  Have checked Dells site and they offer a version of bios 1.1.11 released on 04/09/2007.  Having checked their previous versions and mine is not yet in there.  Don't know if I should go with the 1.1.11 version or stick with what is on mine, any suggestions?  Also, I put in a 500 GB seagate HDD.  Have a 80 GB drive there now which is pretty maxed out.  Playing with the idea to put xp pro on the 80 GB and using the programs and storage 500 GB.  I would like to know if it's a good idea or not!  Could use pointers and how much others who have more experience I have of course on my best options for installation.  for performance and features.  Thank you in advance, Ron.

    It's sad to say, you should probably have spent your money on a new computer rather than on the RAM and a new hard drive.  Windows XP (you posted in a forum of Windows XP, that's what I assume you have) will be supported is no longer starting in April 2014. This means no more security updates and therefore increases the vulnerability to malware.

    That said, your system now-updated can probably support Windows 7. You must run the Windows 7 Upgrade Advisor to check the remaining material.

    As you say, Dell does not list the intervening versions of BIOS with 1.1.4, 1.1.10, so unless someone at Dell or in the Dell forums can tell you what "improvements" in your version or with your version 1.1.10, you have no way of determining that. Based on omissions, I think there were only minor changes in these versions.

    Normally, I would leave the BIOS alone.  Note, however, that Dell "recommends" 1.1.10 be installed because
    The update contains improvements or changes that will keep your system current and compatible with other system modules (firmware, BIOS, drivers and software) software.
    If you want to stick with XP, I would leave the BIOS alone. If you want to install Windows 7 (assuming that there are Windows 7 drivers for all your hardware), I would Setup 1.1.11.  Be sure to read and follow instructions carefully.

    BTW, it's a little surprising that you only have a 80 GB drive.  CNET review of the Dimension E521 said he came with a 320 GB drive.

  • UCS 540 and SPA 112 ATA

    Hello community support!

    I have a UCS 540 and want to connect analog phones via SPA112 ATA. Unfortunately this combination is not officially supported, but several positions indicated that it is possible.

    If someone has an idea or a solution that would be greatly appreciated!

    The SPA gets it's IP address via DHCP from the UCS and points to the NVI UCS interface IP as proxy. the IP Address of the ATA is to ping requests.

    Thank you

    Mike

    You're right, they are not supported.  You can configure most likely that SIP phones in the WEC, but I have never seen an example of configuration of it.  You can start here is how to set up a phone SPA in a WCF router using the SIP.

    Thank you.

    Hello

    As you install apps from the CPU on the server of the UCS, speech application team listed their recommendations here.

    http://docwiki.Cisco.com/wiki/QoS_Design_Considerations_for_Virtual_UC_with_UCS#Guidelines_for_Physical_LAN_Links.2C_Trunking_and_Traffic_Sizing

    You can create a NIC teaming in the ESXi via vSphere client software for traffic from from / destined for virtual machines.

    For C200, we have only one management port and if you use the management for MMIC traffic port, switch option is not available.

    However, if you choose to use host for MMIC traffic NETWORK ports, you can set up CIMC NIC mode for 'LOM shared' which provides the NIC teaming options.

  • Cisco ACS 5.2 with NX - OS (Nexus) devices user - questions

    Hey, I have a really strange problem with Cisco ACS 5.2 and Nexus NX - OS devices.

    I create an account on ACS, let's call him User1 and give privilege 15. With User1, I am able to access on all our IOS, IOS - XE, ASA and PIX devices with privilege 15.

    When I use the User1 account in our NEXUS devices, I do NOT receive the access privilege 15. As you probably know, the NEXUS devices have roles: predefined or custom roles. So I assumed I would get the role of "network-admin" (15 private read/write) User1 when you connect, but instead I got the role of 'vdc-operator' (private 1 read-only).

    Then I tried to twist User1 and give network-admin under profile Shell > Custom Attributes. I logged in the NEXUS and of course I was able to get a network-admin access. However, my access to ALL other devices (IOS, ASA, PIX, etc.) does NOT work! I am not even able to connect with my login and my password for these devices.

    Has anyone ever experience this problem? Help, please!

    Thank you

    neocec

    This is a common problem when you mix with RBAC and IOS devices authorization policies, the pair av that you created must be set 'optional' instead of 'compulsory', please make this change and you will be able to access all your devices.

  • Drag and drop question - Desktop and USB

    Hello!!

    I have an Asus laptop that I bought in September with Windows 8 is installed. I saw drag and drop questions on desktop lately, and I'll provide you with a full run down of what past:

    1. this particular case, I wanted to save my mobile by copying and pasting all the files from my phone to a USB (USB Kingston).

    2. I selected all files, right click to copy, open the folder that I made in the USB for my phone content and do a right-click Paste.

    3. nothing's happened, Explorer seems to have frozen, so I opened the Task Manager and press end task, all closed and restarted my laptop.

    4. I have excluded that my phone was the issue. I was able to create a folder on my desktop and copy and paste all of the content of my phone in the folder on my desktop.

    5. I tried to copy and paste / drag and drop an image from my office to the flash drive. Explorer Windows freezes on the rise again.

    6. I tried another flash drive. Explorer Windows froze again.

    Apparently I'm unable to copy files ON a USB key, which makes the backup and backup of things a headache because Windows Explorer stops working every time.

    I am the only user of this laptop, and I don't know what is happening or what to do. Any help would be appreciated. Windows 8.1 upgrade would solve this problem?

    Hi Karthik,

    1. There is no error message.

    2. I tried earlier drag - move my documents to my flash drive and it works perfectly.

    I just tried again to drag and drop from my office to my flash drive and for some reason, it works again.

    I don't think that was with my flash drives, but with Windows Explorer itself. Nevertheless, it seems to have fixed itself somehow. Thank you very much for your help!
