Should I more SFP + ports host if I add another tray of disk PS6210X

Hi all

We have a cluster of Hyper V of Server 2012 R2 4 nodes with each host with 2 10GbE SFP + dedicated to iSCSI traffic. We need to increase the capacity of the San and our supplier has quoted another shelf but said that we need another 2 10GbE SFP + ports in each of our guests. Is this correct?

I was under the impression that all our guests are already "hooked" in the iSCSI with MPIO active tissue and must therefore not more physical iSCSI connections.

If we opt to not install the additional iSCSI NIC will we lose performance?

Thank you very much

Gary

Probably not. In a virt. environment, you have a random i/o with smaler blocksizes which means less bandwidth. If you have dedicated 2x10GbE you need a couple of members PS do deliver IOPS and fill this huge pipe.

I suggest that you install SANHQ when its not already there and check the width of band and transferrates you already have.

To compare I have 10 members of PS in 2 pools with 11 hosts (each of them have 2x10GbE just for iSCSI) and the sending of PS group around 400 MB/s and up to 1000 MB/s during the backup.

I need an IOmeter and 100% with blocksie 256 KB sequential read workload to fill the pipes 2 x 10 a server.

Kind regards

Joerg

    Hello

    What I understand, that is, you already have a free site hosted with Adobe Business catalyst, and now you want to get a more.

    To do so, publish a Muse Adobe Business catalyst site.

    Access to the administration panel and go to settings-> Site Management site, you should see the upgrade option, you will pay for the site, because it is not a free site.

  • PowerConnect 6248 stacking using the front SFP Ports

    I am trying to stack two Dell Powerconnect 6248 switches. Currently they are chained together, but I modules fibre for the front sfp ports. Theoretically, I should be able to stack them. But when I try:

    stack 1/g45 #stack - port console (config-battery)

    Could not set the front panel stacking mode.

    Any ideas? Thank you!

    The PCT6200 requires a stack of modules installed in Bay 1 (XG1 XG2) at the rear of the switch. The stacking module uses CX4/Infiniband type stacking spacers.

    Stacking of front port / user is not supported

  • PowerConnect 6224: Dell SFP + port supports combine Dell SFP?

    I have a Dell Powerconnect 6224 switch and I installed a Dual Port SFP + Module of adaptation for PowerConnect
    6200 series at bay2 at the rear of the switch. I inserted a transceiver, SFP 1000BASE-LX, wavelength 1310nm 10km Reach in the SFP slot + and the other end is connected to a connector SFP 1gbe. I don't have any link. My question is if Dell SFP ports + supports SFP transceivers or it only supports SFP transceivers +?

    I checked the ports to help an SFP + SFP +, 10GbE, copper Direct Attach cable Twinaxial, and link LEDs are lighting up.

    I believe that the SFP ports + back work with SFP transceivers. Ports before combo will work with SFP transceivers. Another thing to look at is the cable being used. Don't forget that there are specifications that are compatible with transceivers FPS are you wanting to use. A SFP + SFP connection would require that the SFP transceiver + supports a connection of 1 GB.

    Hope this info helps.

    I want 3 months free service. Horrible customer service, lost nearly an hour of my day. There should be more people don't help, no help to try to update my account.

    I just started 2 business and wanted a team plan and more information on this subject, has upset and asked 3 days of free service, they said that they can do, and as I said... NO help for information on business plans, which now, I have to research. I'm in a contract year, but I can add a team business plan but ONLY if I get 3 to 6 months free of my Cloud creative photography service.

    They also tried to disable my account and at NO time asked for my account to be cancelled and a fee for breach of contract.

    Thank you very much for this fix! I also ask that employee

  • What size should be more PGA or CMS?

    While the creation of database of 4 GB which size should be more PGA or CMS? do you recommend the size?
    Thank you.

    You can set the AMM and database automatically select the correct value for the SGA and PGA:
    http://docs.Oracle.com/CD/E11882_01/install.112/e24321/inst_task.htm#BABBBHJH

    Specify Configuration Options:
    Provide the following configuration information, and click Next:
    Memory:
    The Enable Automatic Memory Management option is selected by default. This option enables the database to automatically distribute memory between SGA and PGA. If you deselect this option, then the SGA and PGA must be sized manually.
    
  • I want to improve memory on iMac 27 in. 3.3 GHz, 5K retina. He now has two 4G of Ram. I want to add two 8 G of ram. Should I remove two 4 G, or simply add 8G in two empty slots? Going to have a mixed match (2 of 4 and 8 s 2) in trouble?

    I want to improve memory on iMac 27 in. 3.3 GHz, 5K retina. There are now two 4 G of Ram. I want to add two 8 G of ram. Should I remove two 4 G, or simply add 8G in two empty slots? There are 4 slots for RAM.  Going to have a mixed match (two 4 and two 8) in trouble? Or will it improve my speed giving me 24G of RAM?

    It will be fine as long as they are installed in pairs (and, as long as your model can handle 8 GB modules). Just install them in the empty slots. Working with word documents or online will be not much faster - you will notice the difference in speed apps to respond, with graphic design and video editing, etc or game play. The new OS versions like more RAM, so you can not go wrong there.

    FYI, you do not run iOS on an iMac - Please edit your profile to show what OS version you are using. It helps the helpers.

  • IR hotsync problem: "because the port is in use by another application."

    I finally got my system operation.  Sony Clie TJ - 25 pda, Palm Desktop 4.1, Windows 7 64 bit.  Very delicate balance.  I failed to install the new software released by aceeca.  I finally got it by infrared hotsync.  Several times.

    Now, today, I get the message on the Clie: "could not start the hotsync operation because the port is in use by another application."

    I saw this thread and in fact ensure that the transfer of images using a digital camera box is unchecked.  It still does not.  The icon hotsync in the lower right part of the screen, when I check that IR is checked, nothing else is.  It still does not.

    Thoughts?  Ideas?  Suggestions?

    Cidercat I had this happen to me with bluetooth hotsync before. I listen to radio, transfer files and surf the web with bluetooth. I could solve the problem by turning off the bluetooth, then turn it back on. Sometimes a warm reboot might also work. I came across a free application for the Palm tree named NetworkDown. It closes completely all active sessions down. You type right on the icon to run it. It works on my TX.

  • Cannot ping port host MD3000i on RC0

    Hello

    I have set up my iSCSI network, as suggested in this post:

    http://en.community.Dell.com/TechCenter/storage/w/wiki/MPIO-to-PowerVault-MD3000i-with-Microsoft-iSCSI-initiator.aspx

    I can only ping the ports of controller RAID 1 (two ports). All of my iSCSI traffic is drunk through the controller. Windows Server 2008R2 (R710/810), but also an ESXi 4.1 cluster (R610 and PE2950) access the dedicated iSCSI network. I contacted the support a few weeks ago, and they have replaced the MD3000i RAID controllers as well as the background. They are insistent that there is a configuration problem and would not assist any more beyond to send me links suggested configs. I went through the Setup on the R810 (Windows 2008R2) from scratch. This has not produced different results. Then I updated all drivers (BCM5709Cs) NETWORK card and software on all hosts, successfully restarted the MD3000i and the two MD1000s bike powered two switches HP Procurve 1400 and restarted all hosts. I can't always ping RC0. I Putty and captured RC0 boot logs, but it was not obvious to me. Here are the logs of boot:

    IPs I can ping: 10.182.232.251 and 10.182.233.251 (both on RC1). I can even ping all other iSCSI host initiator ports! I hope I gave enough information about me for some answers. Please advise!

    Thank you.

    What are the 4 IP addresses and subnets for the 4 the MD3000i iSCSI ports?

    ISCSI controller 0 port 0?: (guess 10.182.232.250/24)

    ISCSI 0 1 controller port?: (guess 10.182.233.250/24)

    Controller 1 iSCSI port 0: 10.182.232.251 24 (hypothesis on the mask)

    Port of iSCSI controller 1 1: 10.182.233.251 24 (hypothesis on the mask)

    Wiring must be:

    iSCSI 1 Switch / VLAN:

    ISCSI controller 0 port 0

    ISCSI controller 1 port 0

    Server 1 iSCSI port 0 (in the subnet 10.182.232.x 24)

    etc.

    iSCSI Switch 2 / VLAN:

    ISCSI 0 1 controller port

    ISCSI 1 1 controller port

    Server 1 iSCSI port 0 (in the subnet 10.182.233.x 24)

    etc.

    To test iSCSI on controller 0 port, take a cell phone with a Gbit ethernet port (any modern laptop should have it), connect the ethernet controller iSCSI 0 0, 10.182.232.100 port value IP from the laptop and try to ping 10.182.232.250 (assuming that it comes to the INVESTIGATION period on this port). If it works, change the IP of the laptop to 10.182.233.100 and move the cable to the iSCSI port 1 and try to ping 10.182.233.250 and see if you can ping the IP address.

    If these two are working, the first thing that comes to mind is that the port 0 and 1 have their swapped cables.

  • ASR9001 SFP + port 2 and port 3 disabled auto

    Hello

    Everyone has the same problems?

    We have an ASR9001, when we test the port SFP +, after several days of market, the port SFP + 2 and port3 off yourself.

    The port is disabled only, but not err - disable.

    We can use command 'stop' and 'no stopping' for the recovery of these two ports.

    The fault happened several times and we do not know how to solve.

    Everyone knows the reason?

    Hi David,

    If you use ASR 9001 - S SFP and SFP + 2 and 3 are disabled by default. You can enable with a license.

    If you use ASR 9001, you hit the following bug: CSCug60558 - fix for ASR9001 port flap problem

  • ASA 5510 more and Port forwarding

    Hallo,

    I don't know if the thread title is correctly written, so I'll try to explain my problem.

    I have an ASA 5510 more linking several external interface VPN tunnels to internal interface. they work very well. Now I want to access a server in the internal network of trust on the Internet via RDP.

    I've set up a static NAT rule which translates by [my public ip phone]: 11111 on [the internal server ip]: 3389. Moreover, I met [my public ip phone] traffic: 11111 outside [the internal server ip]: 3389 inside via the access control list.

    Yes, it does not. I made a few soft logic error?

    Code:

    static (exterior, Interior) [the internal server ip] tcp 3389 [my laptop public ip] 11111 netmask 255.255.255.255

    Outside_access_in list extended access permit tcp host [my ip public notebook] [internal server ip] eq 3389

    Best regards

    EYAD Tayeb.

    Hi... I might have a word here!

    looking at your config you have

    static (inside, outside) tcp 3389 11111 netmask 255.255.255.255

    It should be

    static (inside, outside) of the tcp 3389 3389 netmask 255.255.255.255 interface

    Also... Make sure that the aplpied of the access list for the external interface in the outbound direction does not block traffic referred by your inside host with the public client that initiated the RDP session.

    I hope this helps... Please, write it down if she does!

  • Adding more than one host ESX and the upgrade at the same time.  What is the order of preference of the operations here?

    We are budgeting for more licenses and hardware for 2014 and want to do immediately in January.  I am trying to decide what is the best order of operations for adding two vmware hosts additional to our current installation of vsphere and also upgrade our vsphere / esx 4.1 u3 for the latest and best.

    We have 3 Dell PowerEdge R710 running ESX 4.1 U3.  In this vmware cluster, there is a vcenter server 4.1 U3 virtual machine handle this.  The three servers are about 90% memory used so we add 2 additional servers.  Probably the Dell PowerEdge r.620 since we get up 2 in the space of a 710.  Storage is on a san EMC NX4 NFS which will become too but not yet, let's just deal with the vmware part.

    When adding additional r.620 2, should I install ESX 4.1 on them and join them to the existing cluster and THEN pass vcenter and each one esx?  I ask precisely because 90% of use on 3 current servers, I need 2 other servers to support the update operations take place.  They would be able to repel vmotioned vm while each host receives an upgrade at the same time.

    So which is the best way to go about adding of the hosts and the upgrade?  Would I add as 4.1, then they would be available as targets vmotion and so I have room to start the hosts one upgrade at a time?

    If I update vcenter to the latest version, it is comparable backwards and can manage the 4.1 hosts, but also hosts 5.x?  I guess version 5.5 is the last one I would get from VMWare?  It is right of ESXi, then, how is this ESX ESXi 5.5 4.1 upgrade?  How much storage space do I need for ESXi 5.5, as I'm dechatoiement out of these r.620 Dell and need to know what hard drive to put in.

    The steps that you must follow

    -Updated vCenter Server

    -Upgrade of the ESX hosts (because we do a updating of the material we will install 5.5 on our new guests and add them to the cluster and then dismantle our existing)

    -Upgrade VMWare tools

    -Update data warehouses

    ESXi 5.5 has these storage requirements:

    • Installing ESXi 5.5 requires a boot device is at least 1 GB in size. When booting from a local disk or SAN/LUN iSCSI, a 5.2 GB drive is necessary to allow for the creation of the VMFS volume and a scratch 4 GB partition on the boot device. If a smaller drive or logical unit number is used, the installation program attempts to allocate a region scratching on a separate local disk. If a local drive is not found, the scratch partition (/ scratch) is located on the disk virtual ESXi host, linked to the/tmp/scratch. You can reconfigure /scratch to use another drive or logical unit number. For best performance and memory optimization, VMware recommends that you leave no /scratch on the ESXi host ramdisk.
    • To reconfigure / scratch, see Configure the Scratch Partition of vSphere Client vSphere Installation and Installation Guide.
    • Because of the sensitivity of the I/O devices, USB and SD, the installation program does not create a partition scratch on these devices. Therefore, there is no tangible benefits to the use of the great features of USB/SD that ESXi uses only the first 1 GB. When installing on USB or SD, tent Setup devices to allocate a region scratching on a local disk or the data store. If no disk is local or data store, /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
    • In Auto deploy facilities, Setup attempts to allocate a region scratching on a local disk or the data store. If no local disk or data store is found /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
    • For environments that start from a San or use Auto Deploy, it is not necessary to assign a separate logical unit number for each ESXi host. You can co-locate areas scrape for several hosts ESXi on a single LUN. The number of hosts assigned to a single LUN must balance the size of the LUN and behavior I/O virtual machines.
  • What is proxy and proxy port host

    I want to know host proxy and firefox proxy port

    Once you have configured Ultrasurf you can go into the Firefox proxy settings and set the 127.0.0.1 Proxy host and port of the proxy to 9666. Please check this web page for a step by step http://www.how-to-hide-ip.info/2009/02/19/how-to-configure-firefox-to-work-with-ultrasurf/ guide.
