• Brocade M5424 Fibre Channel blade switch fiber?

  Hello.

  Im trying to support this Brocade M5424 switch blade Fibre Channel equipment and its load of the GBIC 10Gbs with fiber LC connectors. What type of fiber patch cord do I need to connect to another switch? I Googled it out and check it: LC LC PATCH CORD AQUA OM3.

  But my question remains... should I fibre om2 and om3 for the best connection quality?

  Could someone help me with this?

  Thank you

  OM2 and OM3 are assessed for 10 GB. 20 meters, you could run OM2 and OM3 and be able to achieve 10 GB. Here is a guide optical and cable with some information that may be useful.

• How Virtual Machines to access the data over a Fibre Channel SAN network

  Hello

  I have storage EMC SAN and HBA Qlogic card installed on a server from VSphere 5

  How do I access the LUN that I created on the SAN on a virtual machine.

  Please help step by step because I am a new on VSphere

  so the trick with rdm, is that there may be any vmfs existing on it. so even if you do not want to perform a new scan, it can be mounted in the storage. delete the vmfs partition, remove it from storage, then go to add HDD on the vm again and rdm will be is greyer. Obviously im assuming that there is no data on this lun. This operation will destroy all information contained in this logical unit number since we reformmatting it.

• UCS Fiber Channel FI for San switch wiring & config

  My question is about the correct wiring & vSAN configuration by the UCS FI switch San (Cisco MDS).

  Currently my wiring is as follows:

  Fi1 port 25 - SW1 port 3

  Fi1 port 26 - SW2 port 3

  Fi2 port 25 - SW1 port 4

  Fi2 port 26 - SW2 4 port

  On the side of the switch San, our guys of storage configured vlan10 SW1 and SW2 as vlan20. For this reason, I was not able to have a vSAN by FI, I read is recommended, because the VLAN switch cross FIs. Now, when I created vHBAs I have 4 vHBAs per server, 2 by IFS by vlan if I want redundancy with a switch or a loss of FI.

  Question: Is this the correct configuration on the side of the SAN switch? Do I actually create 4 vHBAs per server? I do not have my incorrect wiring & I should just be linking FI1 to SW1 on two ports & FI2 to SW2?

  Help or advice would be appreciated!

  Hi Tara,

  There are two ways of wiring of your SAN infrastructure.  It boils down to a design decision. Traditionally the SAN admins prefer to keep their separate/isolated tissue.  In this design THAT MDS-1 only connect to FI - A and MDS-2 would connect only to the FI - B.

  Another option is to connect each MDS at each END.  This gives each FI SAN fabric access and allows to create double VSANS (that exists on each FI) rather than separate them.

  You don't need four vHBAs by UCS Server - some adapters support no more than two in any case.   What you do is create two vHBA by the Service profile, each host will have access both to VSAN 10 and 20.  What you can do is to shift your tissue of vHBA while 1/2 access your Service VSAN 10 via FI - profiles and the other half access VSAN 10 FI - B.  This will help to distribute the load accordingly.

  E.g.

  First 1/2 of SPs

  vHBA0 - VSAN10 - fabric-A

  vHBA1 - VSAN20 - fabric-B

  1/2 second of SPs

  vHBA0 - VSAN20 - fabric-A

  vHBA1 - VSAN10 - fabric-B

  As you can see a bit of a manual balancing can act.  The best scenario would be to isolate (re-cable) to your network SAN fabrics according to the traditional SAN design above.

  Kind regards

• FI6248 FC connectivity with MDS SAN switches problem

  Hello

  We have two FI6248 in a cluster must be connected to two MDS SAN switches, using FC ports.

  However, I am not able to configure the ports on the FI.

  There is no "Set up as FC storage Port" option. I don't see what "configure as FCoE storage Port."

  I have the FC SFP (DS-SFP-FC8G - SW--> 8 Gbps Fibre Channel SW SFP +, LC) installed on the two FI6248 on the first 16 ports.

  No idea what is the problem?

  Kind regards

  The 6248UP unified ports.  The ports can be configured as Ethernet Ports or FC ports.  By default, all ports are of type Ethernet.  The ports that you configure is currently an Ethernet port.  You need config of the ports as FC ports.  Ethernet ports will be on the left side of your FI and FC ports will be on the right side.

  The following link explains how to convert a port UP Ethernet CF.  Since it's on your FI and not a plug-in, you have to restart the FI in last step.

• Fibre Channel card configuration on the host esx 5.1

  Hi all,

  I have three 5.1 esxi hosts.  I have new port 2 8G Fibre Channel cards installed in each and pass the cable FC since the card port goes to the fiber.

  It's my first time in collaboration with CF cards VMware hosts, what else should I do for these cards to be active or updated network in?  A good explanation, Docs and or video would be extremely welcomed.

  Just ask EMC technology to make the zoning on the SAN switch and the LUN masking and card introduced volumes to your hosts on the side storage... after the volumes, simply go to your ESXi, rescan your HBA and create data warehouses.

• Paths always down after returning from a SAN switch at the service

  I had a problem where electricity is cut to one of my SAN switches.  Everything continued to work because all the hosts and storage are connected to a second switch SAN.

  Now that powered the SAN switch back on all paths through the SAN switch are still displayed as out of service.  If I reboot a crowd she restores all of its path through two switches SAN so there is nothing wrong with the zoning on the switch.  I see that the ESXi host host bus adapters connected to the SAN switch, even without reboot, when I do a switchshow (using Brocade switches) and I see that the configuration is correct.

  I tried a new analysis of the HBA, and this removes the paths through the HBA that is connected to the switch that loses power!

  I tried to reset the HBA to get to do a reset of the LIP by publishing: -.

  esxcli fc san storage reset - a < hba >

  for example

  esxcli fc san storage reset - a vmhba1

  and tried to change the State of the railways in assets with

  esxcli storage path together - State = active - path < path-runtimename >

  for example

  esxcli storage path together - State == active - path vmhba1:C0:T1:L1

  None of them have helped and I don't want to resort to restart the host, there must be a better way to bring these paths.

  I use ESXi 5.5 build 1474528.  Want to really upgrade to update 1 immediately.

  I have the advanced of that setting Misc.apdhandlingenable set to 1 and Misc.APDTimeout value 140.  The switch would have been off for more than 140 seconds.  I could try to set Misc.APDHandlingEnable to 0 and simulate the failure once again, but I'm not sure I want to do this because I remember issues with ESX(I) 4.x hosts becoming disconnected from vCenter following situations of CCA.

  Any suggestions?

  I followed it down to the driver used by the Fibre Channel adapter.  I had to update 10.0.100.1 - vmw.550.0.0.1331820 10.0.725.203 - 1OEM.550.0.0.1331820.

  The hosts have been using Adapters Emulex LPe16000 (IBM rebadged in an IBM Flex System).  See 5.5 ESXi hosts don't restore not path storage from the SAN switch failure. Computer services Pelicano so all the details.

• Fibre Channel vs. Fibre Channel over Ethernet

  Hello everyone,

  Have questions about storage of this connection technology:

  1. what kind of cards are required for the FC and FCoE?

  2. do I need these adapters on both sides, server, and storage?

  3. what switches and cables are required for the FC and FCoE?

  Thnx in advance

  1. what kind of cards are required for the FC and FCoE?

  FC = Fibre Channel HBA Qlogic QLE2462 or OEM of Emulex.

  FCoE = cards of convergent network (http://en.wikipedia.org/wiki/Fibre_Channel_over_Ethernet)

  2. do I need these adapters on both sides, server, and storage?

  HBA is required on the server. They connect to FC switches. The switches connected to the SAN, who also has the appropriate maps build-in.

  3. what switches and cables are required for the FC and FCoE?

  FC switches

  Cables could be Multimode, multimode or copper.

• How to locate the fiber channel SAN disks on the ESX Server

  Hi all

  Please help on this

  How to find and configure the fiber channel SAN disks on the ESX Server

  Concerning

  Vijay

  Assuming that you have configured LUNS on your storage space itself you will need to ensure that the ID in the world of fiber HBA on the host ESX (you can see them registered against fiber HBA under storage adapters, WWID) are configured on the switch of fiber access (read and write).

  In the VI Client connected to your ESX host, select the storage adapters tab and highlight the Fibre HBA. Right-click and select Rescan. If you have correctly configured the SAN and the Fibre switch, then the LUNS now appear under the fiber HBA. Go to storage and select Add storage. Follow the wizard through to add LUNS and VMFS format. Do this for each ESX host that you want to see the LUNS.

• Uplink Ports Fibre Channel - UCS GUI Configuration Guide

  Hi all

  Could someone please explain which means that what follows in the Configuration of GUI of UCS guide @.

  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.PDF

  Uplink Ports Fibre Channel

  Manage ports Uplink Fiber Channel FCoE traffic between the interconnection of fabric and the next layer of the

  SAN storage network. All FCoE network-related traffic is pinned to one of these ports.

  By default, the Fibre Channel ports are uplink. However, you can configure them to work as Fibre Channel

  storage ports. This is useful in cases where a Cisco UCS requires a connection to a DAS storage

  Device (DAS).

  My question is, how the FC Port could handle FCoE traffic? My understanding was that FCoE will be lifted and Enthernet connection only.

  The CF module interconnection fabric is the place where the speration of CF vs. FCoE happen, so it's where the FC frame is extracted in the Ethernet frame.

• Fibre Channel frames - UCS

  I was wondering if it really is possible to have the Fibre Channel frames running on a UCS?

  I read these two articles that provide some great information on the implementation of the Fiber Channel Jumbo and Jumbo frames:

  http://datacenteroverlords.com/2013/04/01/Jumbo-FC-frames/
  http://www.ccierants.com/2013/10/CCIE-DC-definitive-Jumbo-frames.html

  Everything in the SAN I'm administration has the ability to set the MTU value until 9036 except for the UCS. For example on NetApp train I can set the MTU by interface on the Cisco MDS I can set the MTU by vsan. However in the UCS Manager when I go to class of service of system quality, the option to set the MTU of Fibre Channel value is grayed out and it doesn't look like there is in any case override the preset frame size. I can set the MTU of the best Effort however my understanding is traffic Fibre Channel in the UCS will use the class system of Fibre Channel.

  Also I noticed that I can set the maximum size of the data on the vHBA field in the UCS Manager but my understanding is the maximum that can be up to 2048.

• Problem with XServe and XServe RAID via Fibre Channel

  Hello everyone,

  I have a problem with my blended Xserve RAID.

  I see in RAID-Admin and configure it successfully (via Ethernet). Connect with our Xserve via Fibre Channel, but the XServe and XServe RAID do not detect each other.

  The fiber on the Xserve channel LEDs are white on the Xserve RAID completely off and permanent.

  RAID-Admin status of Fibre Channel: 'No connection (1 table)' with a red square.

  If I try to open the utility of fiber channel I get the message: "card Fibre Channel is not found." Utility disk OS X can't, too.

  I changed the card connector cable, and made several reboots. But each time the same thing: they do not detect each other.

  Xserve (2009):

  -2.26 GHz Quad-Core Intel Xeon 5500

  -Map of Apple dual-channel 4 Gb Fibre Channel (LSI7204EP)

  XServe RAID:

  -RAID 5 in an array (only on the left with 5 x 500 GB)

  -1.5.1 Firmware

  -Cable Apple 4 Gb SFP - SFP

  Thanks for your help and sorry for my bad English!

  Hi Mpm-Mainz,

  Check if you have enabled LUN masking. To be able to see, you will need to download raid admin 1.5 not the 1.5.1

  Xserve RAID Admin Tools 1.5

  Have you also tried to use the other controller? Even if there is no disc in there, then it should appear in the preferences of fiber card system.

  Thank you

• It is possible to contact PCA9548A (8-CHANNEL I2C SWITCH) using USB-8451?

  Hello

  Now, I'm doing a project related to the smart battery. Now, I read data from a stack using the USB-8451 by smbus. The next step uses the USB-8451 casing to read the data of several batteries through smbus. I chose the PCA9548A (8-CHANNEL I2C SWITCH) to achieve this goal. But when I check the specification of the PCA9548A, there is a fix I2c format to read data from it, I tried several times, but still no can tell me where is the error in my code, or maybe it's impossible to communicate with this chip using USB-8451?

  Here is the fix that i2c read format of PCA9548A

  Why are you usng the script live? Have you looked at the examples of delivery for the 8451? You just need a couple of nodes property to set the rate and the address, and then use the VI to write I2C.

• UCS connection to SAN switches

  I set up direct UCS in the SAN before, but not San switches to connect.  My understanding of the main differences between the two is as follows:

  (1) with SAN switches, you configure VSAN.  To do this, go to the SAN-> SAN Cloud tab and configure your vSAN ID here.  Then in your vHBA template, configure it to use the proper vSAN ID you configured under cloud of SAN.  Nothing else to do here?

  (2) whereas with direct-attached storage connect FI - A SPA and SPB and FI - B to SPA and SPB, with san switches will FI - A ' switch-1' and FI - B is going to "switch-2'."  Is this correct?  If so, anyone know why it should be that way?

  No problem, tbone-111

  As much as I know, that two vHBAs are supported at this time.  It is best to use 1 from the face and side b 1.

  The vHBAs that are used depend on which WWPN you zoned on your boot LUN.

  For the following example, assume the following group:

  1.) my vHBAs are named vHBA_A1, vHBA_B1, vHBA_A2, vHBA_B2 (A tissue face a and B for b-side)

  (2.) vHBA_A1 is the first HBA on my side, and vHBA_B1 is the first HBA on b-side

  AND

  3.) WWPN of the HBA is zoned properly my boot ports storage processor (SP) of the LUN on the FC switch

  AND

  4.) WWPN of the HBA is hidden correctly on my table LUN

  Those are logical, ANDS, they must ALL be true to prevent headaches later.

  5.) disk Array A0 and B1 SP ports are connected to my A fabric FC switch.  A1 and B0 are connected to my fabric B.

  6.) this example of strategy will start A fabric be the path of MBR

  Best practices - FYI, having at least 2 SAN political Boot (1-A-side, 1 for side b and distribute among your Service profiles).

  In my startup policy, I check the will to apply vHBA naming option and specify my names of vHBAs (sorry I have no screenshots available.  Everything started with a new company and do not yet have access lab).

  My primary SAN parameter can be: the main target: wwpn of A0 and secondary target: B1 wwpn

  My secondary SAN setting can be: the main target: wwpn of B0 and secondary target: A1 wwpn

  It would be a good idea to speak with the Admins of storage while you set up the first two servers to boot on each fabric for all troubleshooting.

  If the zoning and LUN masking are configured correctly, you should see WWPN listed during the boot sequence of UCS server to the point where the starting CF driver is loaded.

  Of course, download TAC Cisco on the line, if you encounter obstacles that you can not go beyond.

  I hope this helps,

  Trevor
