2808 LAG for use with VMware ESXi and Linux collage

I posted the month last about setting up my work with groups LAG http://en.community.dell.com/support-forums/network-switches/f/866/t/19537080.aspx servers (I'll effectively implementing implement this Saturday)

I decided to buy a 2808 for my ESXi server get more aggregated connections to my staff iSCSI Linux server but now I'm worried I might have made a mistake to buy the 2808.

After looking in the manual before I realized I could have been mistakenly assuming that the 2808 had STP and LACP, as I can't find LACP anywhere in the PDF file. I guess that the configuration of my Linux machine for 802.3ad is out (a hope to make mode 4), so now for the configuration of my house, I wonder (* 1 *) that I have to configure my VMware NIC team like and what mode of binding should I use on my Linux host? As for the section at the top (my working configuration) (* 2 *) I don't know what to do about the road other than the leave as 'route based on originating virtual port ID "? (This is how our other data centers are configured, but I'm waiting for my admin network as agglomerates ESXi hosts are configured with the channels of port on our cisco switches)

For the House, I want to try to increase the bandwidth by using three NICs in each server, I was hoping that it works:
VMware: Route of IP hash function?
w/Linux: balance-alb?

-VMware:
Before you begin:

-Linux:
* Descriptions of bonding modes *.
+ Mode 0 balance-rr: Round-robin policy: transmit packets in the sequential order of the first available through the last high school. This mode provides load balancing and fault tolerance.

+ 1 active-backup mode: Active-backup policy: only one slave in the link is active. A different slave becomes active if and only if, the active slave fails. MAC address of the binding is visible from the outside on a single port (NIC) to avoid confusion between the switch. This mode provides fault tolerance. The first option affects the behavior of this mode.

+ 2 balance-xor mode: XOR policy: transmit based [(adresse MAC XOR avec destination MAC traiterait de source) modulo County slave]. This selects the slave even for each destination MAC address. This mode provides load balancing and fault tolerance.

+ 3 broadcast mode: broadcasting policy: transmits everything on all slave interfaces. This mode provides fault tolerance.

+ Mode 4 802.3ad: IEEE 802.3ad dynamic aggregation of links. Creates aggregation groups who share the same speed and duplex settings. Use all the slaves in the active aggregator according to the 802.3ad specification.

-Prerequisite:
-1.Ethtool support in the base drivers to retrieve the speed and duplex of each slave.
-Switch 2.A which takes care of IEEE 802.3ad dynamic aggregation of links. Most of the switches will require some type of configuration to activate 802.3ad mode.

+ Mode 5 balance-tlb: Adaptive load balancing transmission: Channel link that doesn't require any special switch support. Outgoing traffic is distributed according to the intensity of the current (relative speed) on each slave. Inbound traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave.

-Prerequisite:
-1.Ethtool support in the base drivers to retrieve the speed of each slave.

+ 6 balance-alb mode: Adaptive load balancing: includes balance-tlb plus receive balancing (rlb) for IPV4 traffic and doesn't require any special switch support. Receive load balancing is achieved by ARP negotiation. Link driver intercepts the ARP replies sent by the local system on their way and replaces the hardware address of source with the unique hardware address of one of the slaves in the bond as different counterparts use different physical addresses for the server.

The topic dell nearest you, I have found a useful was: http://en.community.dell.com/techcenter/networking/f/4454/t/19415629.aspx

my previous post was more concerned with VLAN tagging and spanning tree issues, but now I see I should have feared groups LAG it as well.

Any help would be appreciated, thanks in advance all :)

PS. http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/dell-powerconnect-2800-series-spec_sheet.pdf said that the 2800 series supports LACP, so if I'm worried about anything on my iSCSI side slap me please in the face, but I guess even in this case, I'm still not sure how to configure the ESXi host because it does not support LACP without vSphere and my original configuration is a free version , so I have no web vSphere management needed to make the LACP allow the change.

Not sure if it is of no use: example configuration of EtherChannel / switches control protocol LACP (Link Aggregation) with ESXi/ESX and Cisco/HP (1004048), but that's where I was to base the choice on IP hash from.

It must have the support of layer 3 to achieve IP hash, IP addressing is a 3-layer technology, so a 6200 series or higher or the soon to be released N3000 series.

  • Anyone run a Terminal servers virtual with VMware ESXi 3.5 If Yes please share your experiences?

    Hello guys,.

    We are runnig Terminal Server with Windows Server 2003 Ent in a cluster environment (TS 7), we plan to go with VMware ESXi 3.5 to virtualize the TS. Does anyone have any kind of experiences that can help make a decision?

    Thank you.

    Keep an eye on the side esxtop ESX and see your % RDY meters in this output.  Don't forget, as underlined chamon, with high vSMP values do not match always the best performance.  Typical scenarios citrix/ts use 1-2 vCPU for more effective results.  If you bump up to a larger number of users, you also want to watch the overcommitt on your processors and vCPUs in the box.  Many users a lot of switching and use heavy context on the processors for the management of the OS and the user.  1-2 vCPU seems to be the sweet spot.  What kind of applications are underway within the environment?

  • Hot migration is possible with VMWare ESXi 5.1.0 without an ESX server management

    Hot migration is possible with VMWare ESXi 5.1.0 without an ESX server management?
    I wonder for a future issue, a scenario where a system administrator must build a Win2008 + DC on local storage, server
    then, once the physical box is integrated into the class network, the physical box is connected to the classified SAN storage.
    Is it possible to hot - migrate the server Win2008 + CC local storage to SAN storage at this time, with only the
    free version of VMWare ESXi 5.1.0?

    Welcome to the community - I guess that you are looking to do this, while the virtual machine is currently running - this is not possible without a management server, also called vCenetr, but all is not lost because you would be able spend the VM local storage to the San with the VM posered using the client storage management features

  • VCenter Server with VMWare ESXi free 5 5

    Hi all

    Test the VCenter Server 5 Evaluation (60 day trial) to management all my 5 of VMWare ESXi (free license). It works with restrictions. These restrictions aren´t a problem for me. I need only to move (power off of virtual machines), clone, create templates for and organize my servers in a single interface VSphere Client. So, I would like to know what type of license of VCenter Server 5 woks if VMWare ESXi 5 free. Buy the VCenter Server 5 Standard?

    Another doubt is if VStorage works with VMWare ESXi free license I.

    Best regards

    Fabio Sobral

    Unfortunately the free ESXi hosts in vCenter management is not possible (except for the eval). The hosts of ESXi need a vCenter Server Agent license that is only available in editions 'paid' of ESXi.

  • External hard drive for use with FCPX Thunderbolt

    I got a new iMac, but the SSD in it's tiny, so I need to invest in an external drive at least some of TB.  Should I go Thunderbolt because I think it's faster?  I'm looking at Fantom and Lacie but I'm not sure what would work best for use with FCPX.

    Any tips or suggestions for these two manufacturers?

    Thanks in advance for the help.

    Well, a disc of Tb2 (which takes care of your iMac) will offer excellent performances. If you need these speeds depends on really how ask your projects are. A USB3 drive will be fast enough for the vast majority of HD projects. Expect to spend more for the readers of Thunderbolt2.

    Here is a good article on configuring systems with external drives.

    Good luck.

  • What is the best HDMI switch for use with Apple tv 4

    What is the best HDMI switch for use with Apple tv 4. I heard some do not work and the automatic switch has problems because Apple tv is still using power?

    I installed on a cutting and not because the automatic switch works because it isn't always. It came with a remote control that is almost as good, so don't mind the fact that automatic switching does not work well. The reason why I chose cutting is because it was the first device that gave me the good picture and sound quality with my AppleTV, the Xbox 360 and the PS4. (Don't ask!)

  • HP: unlock OEM windows 7 for use with another computer?

    Hello

    I recently got a HP computer with an OEM windows installation 7. After the machine (fatal hardware failure), I tried to use the windows key to install it on another computer. However, the key is an OEM product and would not activate, so after talking to microsoft they sent me here to ask if the manufacturer could "unlock" the key for use with another computer (that I build from scratch).

    So all this possible? Or do I have to buy a new license?

    Okay, Ive talked to HP and microsoft and it turns out that the key has been blocked (pirates). So much for the purchase of second hand.

  • Any camera regardless of the interface is available for use with the LabView interface.

    Hello

    I intend to go for some CMOS camera,

    but I have a huge doubt before buying, the camera of menttioned above is not anywhere in this list. Nor can I see any type being supported USB device.

    The question is

    1. is a camera regardless of the interface is available for use with the LabView interface?
    2. Can I build a VI to communicate with any device image and recording of camera and take the data?

    Any kind of help or advice is greatly appreciated... I have to buy a CMOS camera and begin to run.

    Thank you...

    Hello Virginia,.

    I am pleased that this information has been useful, one thing I wanted to mention is that USB 3.0 has its own standard USB 3.0 Vision which is currently not supported. If this camera is also Direct Show compatible then you will be able to acquire an image using IMAQdx and manipulate all the attributes that are published to the API Live Show.

    I hope that USB 3.0 Vision will be supported in the near future, and we tentatively announced for this standard of communication for the August 2013 Vision Acquisition Softwareupdate.

    See you soon,.

    Looking at the website of Olympus, it would appear that we do not
    There are.

    But you do not need a driver because you do not need to connect your
    camera to the computer. Just put the memory card in a card reader and
    access like this instead. I prefer to do it with my camera,
    because it is easier, faster and uses no battery in the camera.
