iSCSI Multipathing vs just make the NICs active/active (vSphere)

Hello

I have 2 physical cards in my iSCSI vSwitch for dedicated and I understand that if I want to use multipathing I need to create 2 VMKernel ports, assign to each NETWORK adapter and connect them to the iSCSI initiator using the CLI interface.

It is, what are the benefits this new management feature gives multichannel just teaming network adapters in an Active / Active configuration? The two configurations are not only as redundant ones than the others?

Thank you

Pete

MPIO allows a server with multiple NICs for transmitting and receiving of I/O across all interfaces available in a compatible SAN corresponding MPIO.  If a server had four 1 GB/s network adapters and SAN had four 1 GB/s network adapters, the theoretical maximum rate would be about 400 MB/s (3.2 Gbit/s).

Aggregation by grouping NETWORK adapters (or LACP, PAgP, 802.3ad, etc.) doesn't work the same way. Aggregation of links does not improve the throughput of a single traffic flow (a single source of communication with a single destination).  Only one stream will always travel the SAME path.

The advantage of the aggregation of links is seen when several 'unique' streams (each with different source / destination) exist.  Each individual stream is sent down from its own available NETWORK adapter interface (computed by a hash algorithm).  Most unique feeds, most used network cards, more view aggregate throughput achieved. Aggregation of links will not improve throughput for iSCSI, although it gives a degree of redundancy.

I hope this helps.

  • Is Installer-upgrade just make the server? What shell hyperic?

    I installed the Server 3.0 to 3.1 hyperic

    I downloaded hyperic-hq-installer-3.1.0-439-amd64-linux.tgz and made a
    tar - xvzf hyperic-hq-installer-3.1.0-439-amd64-linux.tgz.

    I then /opt/hyperic/hq/hyperic-hq-installer/setup.sh-mise to level. This upgrade of the server
    Would I able to use this Setup program to upgrade the agent also. HOW?
    I downloaded the agent only and all installed package, but I was wondering if I should?

    Also how to pass shell hyperic?  Would I could again use the--upgrade
    with other options to include the agent and the shell

    I don't see any mention upgrade documentation to specify anything except - upgrade

    I returned and used the setup.sh - full and just choose the hull of HQ to install the new shell. Again could I have updated it with the hyperic-hq-installer-3.1.0-439-amd64-linux.tgz file Setup?

    Hi Mike,.

    A note: this has been asked several times. In the future, please see the docs - http://support.hyperic.com/ - and research first on this forum.

    As a reminder, the "-upgrade ' flag is for the server. 'Improve' agent and the shell (really, you're just replacing the whole directory) run setup.sh and install the agent and the shell. The beam of the agent does not have the shell, you must use the installation for this package.

  • Why not just make the Blue Star add bookmarks to the Menu "Favorites"?

    Why is the easiest option to add a bookmark must dismiss this bookmark to the phantom Zone?
    I guess that very few people want their bookmarks to be added to the section "Unsorted Bookmarks" directly by default, so why the star do this by default? I have given anecdotal-search engine to support my claim, with many people asking a semblance of this question I'm wondering now, and even more that involve people get confused and asking a version of ' where my favorites gone? "after using the icon star, to ignore the"Unsorted Bookmarks""section", if we can call such a 'section '.
    I looked in the preferences of an option to change it so the Blue Star would automatically add them to the "Bookmarks Menu" instead of sodding them to Nowhereland, but I'm either missing or it is not there. I did Google for a bit, but I'm tired of dogged by similar information but largely unrelated, or the aforementioned confusion.
    I know, I know, I * can * "right click", or I * could * 'double-click' the star icon and change the folder, but why should I do first? It removes the convenience of the "convenient" option
    So, the star is, mock me, laughing at my multiple clicks wasted, ignoring that there no mortality of its own to meditate and still somehow with this lack of information against me.
    All I wanted was a better way, and it's right there in my face, close enough that I can * click * it, but still far enough away to make fun of my simpler desires.
    Thank you for what I guess has your time and review and any hypothetical help you can try to offer.

    You can use the shortcut Ctrl + D (bookmark > bookmark this Page) to have the page my favorites in the Menu folder bookmarks.

  • Why several vmkernels for iSCSI multipath?

    I'm a little confused about the iSCSI Multipathing. What is the reason for the creation of two vmkernel interfaces and then use command line tools to link them to a new vmhba? Is it different for the use of a software iSCSI initator on a vSwitch with multiple VMNIC, connected to different physical switches?

    There is the same discussion in thread Russian vmug.

    iSCSI Multipathing is not on the trail, its about us pairs - initiators (interfaces vmk) and targets.

    If you have two targets

    • and you need to fail over only - 1 vmk is enough (NIC in Active mode / standby)
    • If you need loadbalacing
      • and you can use the aggregation of links + Hash IP - 1 vmk is sufficient (PSP is Roundrobin and NICs in active/active mode)
      • If you cannot use THE - vmk 2 are needed.
  • I used even to make the Blurays for a long time, with success, with no problems. Today, on my current project (.iso file estimated size ~ 19 GB) MENUS rendering time is reported as 31 + Hrs. Is this OK, or is there a problem?

    My system: 2013 Mac Pro: Core, 64 GB of Ram, two GPU of D700 12 / 3GB. I was creating an ISO image file using ENCORE 6. I am currently using the latest ADOBE CC system.

    The menu on which rendering takes a while has three normal buttons linking to 3 first videos produced. The menu has a long file AUDIO (about 90 minutes) as an attachment.

    After letting the rendering process to continue for 4 hours, on the audit of the progress window, progress bars seemed not to be ahead. I waited 2 + hours of overtime and checked again. Progress bars have been in the same place (no deposit). Activity monitor showed that still was still running. At this point, I cancelled the task. Then, I wanted to just MAKE THE MENUS. It is currently running for the 95 + last minutes. Details 'Render' reported ~29.5+ hours as TIME REMAINING. The number of processed IMAGES currently shows ~ 27000 + showing as 169065 in total. The meter for executives of the ongoing transformation to increment of the above stated figure of snapshot of 27000.

    I think that maybe I should let it continue to operate at the end (i.e. 30 hours of rendering time, if all goes well). Is - this sound NORMAL?

    Any advice will be appreciated.

    Never tried such an audio file for a long time. Are you sure that there is no video movement in this menu?

    What format is the audio file?

    Hi all

    We get a strange question in BPEL production environment.
    In the assign activity, there are 3 variable hardcoded with some default values.
    At runtime, a variable is to take more time from 1 minute to initialize just this default value.
    We do not get this problem of time in Dev and Test environments, so we are not able to test this.
    Please look in the Audit trail for the BPEL instance in the Production environment.
    Request to let me know if them work around or fix for this issue.



    Thanks in advance,

  • How to make the new version, I just installed as the old work that has stopped working?

    I used Thunderbird for many years and have always been very satisfied.

    A few days earlier, he has stopped working on my computer. I think that this was due to an update of AVG Free 2015. (When I restarted after the automatic update, Tbird and Chrome and Firefox broke everything. AVG has since been removed and replaced with Avast. Chrome and Firefox, both work very well after I installed the latest versions.) I took the opportunity to get the latest version of Tbird (I was 37) and installed it. TBird is OK, but the operation is a total disaster!

    He used to see me just like the user. Now I have to choose my Inbox by clicking, and then open it in a new tab. I could accept this pain if things worked OK. The first email that I click appears in the message pane. But I can't delete it unless I double click to open in a new tab! I can not get the following message to be displayed in the messages pane. It's used to work if I simply clicked on the message.

    How can I make Tbird work as he did? I used to love, now I hate it! Please help me before I dump Tbird and switch to Gmail!

    Thanks for any help.

  • I have 6 profiles but should clean up so I did only 1 'inbox' and 1 'sent' - just converted from Eudora 7 and trying to make the similar user interface.

    I just converted to Eudora paid 7 (after many years) to Thunderbird, due no problems of SSL certificate supported by Eudora.

    So far, I like Thunderbird but tried to imitate the simplest UI for Eudora. In Thunderbird, my 6 profiles are listed, each with its own subfolders «Inbox, drafts, sent, Trash & Archives» There is a long list of menu on the left side of my screen.

    Is there anyway that I can consolidate these profiles so that all incoming messages appear in an Inbox, regardless of the target profile. Similarly, can I consolidate the 'sent' and other subfolders?

    Thanks for any help you can give.

    Dave (Thunderbird newbie).

    lets start terms.

    A profile is something that keeps all your settings of Thunderbird. I think that your calling account profiles. but I could be wrong.

    You have two options here.

    First for POP e-mail accounts, you can use the global Inbox Menu Tools > account settings > server settings > advanced Note that makes the account disappear from the folders pane, so that the messages should be moved to the Inbox of the local folders first.

    For IMAP accounts, there is the unified view of the folders view menu > folders > unified. IMAP accounts can simply not use a record combined due to the synchronization of messages with the server.

    Be very sure of what type of account you set up. IMAP accounts for those who have not used their and aren't aware of the synchronization of emails can be a 'new game '.

  • How can I make the best use of a new external hard drive and a new catalog full of photos just loaded into Photoshop elements 14 Organizer?

    How can I make the best use of a new external hard drive and a new catalog full of photos just loaded into Photoshop elements 14 Organizer?

    Keep all the files on external hard drive image?  Nothing else and no pictures on the desktop?

    Keep all image files both places?

    What is the best way to go through thousands of images in the Organizer to identify and place them in files?

    Once I've placed a file, I just leave it in the entire catalog or a way indicate to me that it has been sorted?

    As overwhelming, any tips/shortcuts/schemes, you can offer are welcome!

    As I only have the version of the EP, here is some info on the organiser:

    https://helpx.Adobe.com/Photoshop-elements/how-to/use-elements-Organizer.html

    Independent of how this feature works, you want to have your photos in one place and have a backup (second copy) somewhere else. All hard drives will not be successful at some point - some more early, some late - never trust to have your files in any safety devices if they are on a single disc. Once you have your sorted, it would be useful that you will organize/name/tag new photos immediately if the task is relatively short and simple. I copy my photos on my internal hard drive for my camera, take a quick look with preview to see who needs some changes and then decide where to put them - either drop them immediately after naming them or bring in an editing application and then file them away.
