Cisco UCS FC Direct Attach Question

We are looking at the Cisco UCS as a replacement for our existing servers and SAN switches. As I understand the fabric interconnect can replace our existing SAN switches and that we will still be able to zone the ports just like we do on our SAN switches today.
Can someone confirm how using the fabric interconnects as a replacement for our SAN switches will work? I read that the fabric interconnects have to be in switch mode for this to work. How does this affect the other connections we will have to our Ethernet network?
Thanks.

Q1: The 6120s run in NPV (N_Port Virtualization) mode which means it acts as a proxy for the blade vHBAs and doesn't participate in flogi (fabric logins). When a fabric switch runs in this mode it requires an uplink to a faber switch for flogi and zoning. Due to this you cannot direct attach the the 6120 to an array's front-end fiber ports.
Q2: Yes you can uplink the 6120 to a Brocade fabric as long as the Brocade supports NPIV.

  • Can the Cisco UCS 6120XP direct attach the EMC CX4-120 by fibre protocol ?

    Hi all
    I have two question for Cisco UCS
    Q1: Can the Cisco UCS 6120XP direct attach the EMC CX4-120 by fibre protocol ?
    Q2: I know the UCS 61XX Series support the Cisco SAN Switch(MDS).But we are only Brocade san switch ,
          so  UCS 61XX Series supoort Brocade san switch ?
    Thanks , I really want to know the information .

  • UCS direct attach to NetApp in Flexpod

    Hello Experts,
    We have a new project  which is based on Flexpod design and needs a direct attach between the FI 6248  and NetAPP storage.(Without a Fabric Switch N5K or MDS)
    We had concern if Cisco  has validated this design.Or else if there is CVD(Cisco Validated Design) based  on Direct attach of UCS with NetAPP storage.Also if there is/are any constraints  / limitations that must be considered in such a direct attach  design
    Is there any document (CVD) by Cisco or NetApp which details the diagram/configuration steps and other relevant information for the direct attach between UCS FI and Netapp storage.
    FYI: The architecture will be like this
    2 FI6248
    1 5108 Chassis
    1 B200m2 and 1 b200m3 Blade
    2 2104 IOM
    No Fabric Switch between FI and NetApp storage.
    An early response will be very much appreciated and a useful doc with details.

    Thanks Abhinav and Matthew,
    Now Since UCSM 2.1 supports direct-attached NetApp.So to validate the architecture I updated by UCSM to 2.1.1a and now it should support a direct attach NetApp with UCS System.
    I have conncted ports 31 and 32 of both FI (FC Stoarge Port with required SFPs) to my NetApp Device.But problem I am facing is,it says Link failure or not-connected and is in Orange Colour.Any idea where am I wrong?
    I dont want to use FCoE Traffic or NFS between FI and NetApp.I want to use the FC traffic between UCS and NetApp.Is it possible and if yes How?

  • Direct attachment of a server to 6100 UCS

    Hi,
    I would like to know if i can directly attach a standalone server with 10G CNA to the UCS 6100 10G port and it login to the switch. For example the way we do with c5020 switch. In the 6100 CLI config guide i have not seen any command like binding a vfc to a physical eth int or VSAN FCoE VLAN association.
    Also can any one please explain at present how it works? I see from config guide it connects to the Blade chassis below. I guess the hardware where 10G ports from 6100 are connected is a fabric extender sitting on the blade chassis.
    If i have a fabric extender connceted to 6100 and let my server connect to the FEX, will that work? I am just trying to learn connectivity point of view.
    Thanks.

    This video is helpful but it did not answer many Qs i have related to appliance port configuration.
    As my FI is independent POD, i dont need End-Host mode right ? At least on the Fabric side. In the LAN side i guess it does not matter ? Can any one correct me please ??
    Also once i configure the applicance port, where the appliance port will log in ? I did not see a show flogi database command. Besides i am not sure, if the UCS FI can work as FCF? Am i expected to see Discovery Advertisement that usually FCF sends to VN_port? How about LLDP? Can it negotiate LLDP with the appliance port which has SP-MA supported CNA.
    Thanks,

  • FAS3220 and FAS2240 direct attach on fabric interconnect 6296UP

    Hello everybody
    I have the following architecture
    1 Cisco Catalyst 6509-E
    1 Cisco Catalyst 3560-x
    2 Fabric Interconnect 6296UP
    1 FAS 3220 (principal storage)
    1 FAS2240 (vault backup)
    1 chasis cisco UCS 5108
    5 blade servers Cisco UCS B200M3
    Firmware version: 2.2(3c)
    Fabric Interconnect are direct attach on fabric interconnect 6296up and the ports are configurated as FC storage ports
    My question is the following:
    Can I zoning fabric interconnect with FAS3220 and FAS2240?
    Can I present LUNS of FAS2240 and FAS3220 at the same time on the same boot policy, same san boot policy, and the same organization?
    Thanks for your help

    Well, even if that was possible. You're accounting for a critical failure - i.e. a failure of two redundant devices (both 3220s, which I would have assume would be running in a cluster ... or 7mode). 
    While just upstream you have a single cat 6500 - which would be a single point of failure. 
    Logic would dictate to account for a single device failure all across the path before looking into multi-device failure. 

  • N5K FCoE direct attachment storage conf sample

    I am looking for a configuration sample of two N5K's connecting directly to a single storage device (direct attachment) using at least 2 VSANs, looking specifically for the zoning configuration. This will be a temporary solution while MDS ports are not available for the new enviromment. Please, share any simple configuration using the presented scenario: 2 N5K's, 2 EXS hosts (1000V), 2 VSANs, 2 Zones, and single storage (ie.: N-series). Thank you!

    Hello,
    For the first question, it is NOT supported.
    It might work if we enable default zoning but it is not recommended.

    Hi Jackson,
    Yes its is possible.    Connect the storage array to the fabric interconnects using two 10GB links per storage processor.  Connect each SP to both fabric interconnects and configure the ports on the fabric interconnect as “Appliance” ports from UCSM
    For more information on how to connect Netapp storage using other protocols like iSCSI or FCOE  please check the url below.

  • Cisco UCS 6248 and Dell EQ 6510x

            We have a Dell EQ 6510x we have in production and we are about to power on a Cisco UCS B series chassis and a pair of 6248UP FIs. I'm planning to connect the 4 6510x 10G ports directly to the 6248 FIs and set them as Applicance Ports.
    My question is would be be better to connect the 6510x Primary controller's two 10G ports directly to FI-A and the standby controller 10G ports directly to FI-B, or stagger them? Stagger meaning Primary Controller one10G to FI-A and one 10G to FI-B then Standby controller one 10G to FI-A and one10G to FI-B. Thanks!

    Hello there,
    In your design always keep in mind that both UCS FI are separate switches, they always will talk each other by the upstream switch. The best pratice is connect anything that have to talk with UCS domain in the upstream switch.
    If there is no option to do so, you can connect through the FIs, using a appliance port. In your case I believe that connect stagger mode is the best option, but I'm not sure, depends how your vnics are configured and if your Dell EQ can do port-channel in active-standby mode.

  • FCoE options for Cisco UCS and Compellent SAN

    Hi,
    We have a Dell Compellent SAN storage with iSCSI and FCoE module in pre-production environment.
    It is connected to new Cisco UCS infrastructure (5108 Chassis with 2208IOM + B200 M2 Blades + 6248 Fabric Interconnect) via 10G iSCSI module (FCoE module isn't being used at th is moment).
    I reviewed compatibility matrix on interconnect but Compellent (Dell) SAN is only supported on FI NXOS 1.3(1), 1.4(1) without using 6248 and 2208 IOM which is what we have. I'm sure some of you have similar hardware configuration as ours and I'd like to see if there's any supportive Cisco FC/FCoE deployment option for the Compellent. We're pretty tight on budget at this moment so purchasing couple of Nexus 5K switches or something equipvalent for such a small number of chassis (only only have one) is not a preferred option. If additional hardware acquisition is inevitable, what would be the most cost effective solution to be able to support FCoE implementation?
    Thank you in advance for your help on this.

    Unfortunatly there isn't really one - with direct attach storage there is still the requirement that an upstream MDS/N5k pushes the zoning to it.  Without a MDS to push the zoning the system it's recommended for production.
    http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/2.0/b_UCSM_GUI_Configuration_Guide_2_0_chapter_0101.html#concept_05717B723C2746E1A9F6AB3A3FFA2C72
    Even if you had a MDS/N5K the 6248/2208's wouldn't support the Compellent SAN - see note 9.
    http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix8.pdf
    That's not to say that it won't work, it's just that we haven't tested it and don't know what it will do and thus TAC cannot troubleshoot SAN errors on the UCS.
    On the plus side iSCSI if setup correctly can be very solid and can give you a great amount of throughput - just make sure to configure the QoS correctly and if you need more throughput then just add some additional links

  • UCS C240 M4 with Cisco UCS VIC1227 VIC MLOM - Dual Port 10Gb SFP+

    Hi All,
    Have a few UCS C-series questions:
    If I have a UCS C240 M4 rack server with Cisco UCS VIC1227 VIC MLOM - Dual Port 10Gb SFP+, but do not have fabric interconnect(s), I cannot use the UCS VIC1227 for anything, can I? The VIC ports HAVE to be connected to the FI(s) in order to be integrated with the UCS Manager. There is no local UCS manager software running on the server itself, is there?
    It is useless to have this card in the server without the FI(s), isn’t it?
    The OS that is going to be installed on the server is not going to see those 10GB ports on the VIC, isn’t it?
    And if there are no additional PCIe NICs installed in the server, I am stuck with the two 1GB onboard NICs, is that correct?
    Any input is appreciated.

    do not have fabric interconnect(s), I cannot use the UCS VIC1227 for anything, can I?
    The VIC 1227 can be used to integrate the server with UCSM, but that does NOT mean that is its unique function... the VIC 1227 is a CNA card that can be used whether your server is in standalone mode (no Fabric Interconnects) or integrated with UCSM.
    If the server is not connected to a Fabric Interconnect (FI), it still has CIMC (Cisco Integrated Management  Controller) which can be configured by attaching a monitor to the server and a keyboard, press F8 when you see the Cisco logo and then you can configure the IP, subnet, gateway, NIC mode and others... this may help: https://www.youtube.com/watch?v=KHQBvwO7pUU

    It is useless to have this card in the server without the FI(s), isn’t it?
    It is NOT useless to have the card in the server without the FIs, having the servers integrated only allows you to take advantage of the flexibility of Service Profiles but the VIC card still has the same capabilities whether you have an FI or not.
    The OS that is going to be installed on the server is not going to see those 10GB ports on the VIC, isn’t it?
    See above
    And if there are no additional PCIe NICs installed in the server, I am stuck with the two 1GB onboard NICs, is that correct?
    Same answer as above

  • Cisco UCS network uplink on aggregation layer

    Hello Cisco Community,
    we are using our UCS (Version 2.21d) for ESX Hosts. Each host has 3 vnics as follows:
    vnic 0 = VLAN 10 --> Fabric A, Failover Fabric B
    vnic 1 = VLAN 20 --> Fabric B, Failover Fabric A
    vnic 2 = VLAN 100 --> Fabric A, Failover Fabric B
    Actually UCS is connected to the Access Layer (Catalyst 6509) and we are migrating to Nexus (vPC). As you know, Cisco UCS Fabric Interconnects can handle layer2 traffic itself. So we are planning to connect our UCS Fabric Interconnects directly to our new l3 nexus switch.
    Does anyone have connect the UCS directly to l3? Do we have to pay attention to something? Are there some recommendations?
    thanks in advance
    best regards
    /Danny

    we are using ESXi 5.5 with dvswitche (distributed vswitch). In our cisco ucs powerworkshop, we discuss pros and contras of hard- and softwarefailover and we commit to use hardwarefailover. It is very fast and we have no problems actually.
    This is a neverending and misunderstood story: your design should provide load balancing AND failover. Hardware failover only gives you the latter.In your design, you just use one fabric per Vlan, what a waste !
    And think about the situation of a failover on a ESXi host with 200 VM's; one has to send out at least 200 GARP messages, and this is load on the FI CPU. Most likely dozens or more ESXi server are impacted......
    Cisco best practise: if you use softswitch, let it do the loadbalancing and failover, don't use hardware failover.
    see attachment (the paper is not up to date,
    For ESX Server running vSwitch/DVS/Nexus 1000v and using Cisco UCS Manager Version 1.3 and below, it is recommended that fabric failover not be enabled, as that will require a chatty server for predictable failover. Instead, create regular vNICs and let the soft switch send
    gARPs for VMs. vNICs should be assigned in pairs (Fabric A and B) so that both fabrics are utilized.
    Cisco UCS version 1.4 has introduced the Fabric Sync feature, which enhances the fabric failover functionality for hypervisors as gARPs for VMs are sent out by the standby FI on failover. It does not necessarily reduce the number of vNICs as load sharing among the fabric is highly recommended. Also recommended is to keep the vNICs with fabric failover disabled, avoiding the use of the Fabric Sync feature in 1.4 for ESX based soft switches for quicker failover.

  • Zoning in direct attached storage environment

    Hi everibody,
    I have a small humble question about zoning.
    When using JBOD, each physical disk had its own WWPN and FCID. The zoning configuration is for a server WWPN against disk WWPN so basically each server has its own disk.
    Now for more advance storage systems (such as EMC) instead of physical disks to be mapped to servers we are mapping LUNs per server. I thought that for each LUN a WWPN and FCID are created and then you map the server to that LUN’s WWPN. Now I see that it does not work this way.
    I have a UCS system with direct attached storage (EMC VNX5100). The active zoneset shows that all servers WWPNs are mapped to the same target WWPN (which is the EMC). There is a zone entry for each server.
    So basically the result of that is that all servers can access the same target and the EMC controls the isolation of the LUNs from other servers.
    If this is correct, then my question is why do I need the zoning configuration in this scenario ? why not set the default zone to permit and let EMC control LUN access?
    BTW, this scenario of one storage system attached to the SAN is the same if we use Nexus 5k, so why bother and set zoning if the EMC can control the access to LUNs?

    If this is correct, then my question is why do I need the zoning configuration in this scenario ? why not set the default zone to permit and let EMC control LUN access?
    You could of course create multiple Storage Target Policies (different FC interface on controller, resp. other storage arrays)
    Zoning is just another level of security, default zone permit is not recommended to be used in productive environments. The standard classical procedure is: zoning AND lun masking / mapping.
    In the case of N5k, you have to do the zoning manually (CLI), or with DCNM-SAN; in the case of local zoning on the Fabric Interconnect, UCS Manager does it automatically for you. 
    Hope that helps !

    hi!!
    I need to do an upgrade from 1.4(3m) to 2.1(1a)!
    i've 3 chassis 5108 ( 6 fex 2104xp ) with server B200 M2 and B440 M2. i've two Fi 6120Xp in cluster mode.
    i've check the prerequisite to upgrade but i've a question about default zoning;
    iv'e brocade switch 5300 ( fw v6.4.1 ) attached to Fi 6120xp
    i've SAN configured :
    i've no other configuration under San Tab.
    The documentation says:

  • Windows 2008 R2 on Cisco UCS B200M networking problems

    This is driving me completely nuts.  Let me start by saying I am new to blade servers and Cisco UCS.  I did take an introduction class, and it seemed straight-forward enough.  I have a chassis with two B200M blades, on which I am trying to configure two Windows 2008 R2 servers, which I will eventually make Hyper-V servers.  This is all in a test environment, so I can do anything I want to on them.
    Right now I have installed W2008 directly on hard disks on the B200M hardware.
    The problem is this: even though I think I've configured the network hardware correctly, using the Cisco VIC driver software, I cannot get networking to work in any reliable way.  I cannot even get ping to work consistantly.  I can ping my local server address, but I cannot ping my gateway (HSRP address).  When I try, I get a "Reply from 10.100.1.x: Destination host unreachable (x being each particular server's last octet). I CAN, however, ping the individual IP addresses of the core switches.  I can also ping some, but not all, the other devices that share the servers' subnet.  There are no errors being generated, the arp tables  (for those devices I can ping) look good, netstat looks OK.  But I cannot get outside the local subnet...
    Except when I can.
    There are times when I can get all the way out to the Internet, and I can download patches from Microsoft.  When it works, it works as expected.  But if I reboot the server, oftentimes networking stops working.  Yet another reboot can get things going again.  This happens even though I've made no changes to either the UCS configs or the OS.
    I cannot figure out any reason when it works at some times and not at others.  I've made sure I have a native VLAN set, I've tried pinning to specific ports on the Fabric Interconnects.  There is just no rhyme or reason to it.
    Anyone know of where I can look?  I'm very familiar with Windows on stand-alone boxes (although it's no longer my area of expertise), and I manage a global WAN (BGP, OSPF, Nexus 7k, etc.) so I'm no dummy when it comes to networking, but I am utterly stumped on this one.        

    The problem was this: while the NICs on the blade server are called vNIC0 and vNIC1, Windows was calling vNIC1 "Local Area Connection" and vNIC0 "Local Area Connection 2".  So what I configured on UCS did not match what I was configuring in Windows.  Completely, utterly ridiculous.
    Anyway, networking is working now without any issues.  Thanks for you suggestion; it did get me looking in the right direction.
