ESXi 4 has Jumbo frame support?

Similar Questions

• ESXi 5 and Jumbo frames

  What is the proper way to configure some jumbo frames for an ESXi cluster used shared storage NetApp?  Configure extended frames to the bottom of the VM Guest NETWORK card or I stop at the dvSwitch?  I already configure jumbo images throughout the storage on the physical hardware.  It's just the virtual machine where I'm not sure and if I do not set up the virtual machine, will there be problems?

  Thank you!!

  Then, you don't need to do anything for the virtual machines.

• No on free ESXi 4.1 jumbo frames?

  Hello

  I'm testing a Dell R710 connected to a SAN, iSCSI and Dell MD3200i according to the documentation, I find that I am out of luck if I want jumbo frames because it must be configured using the CLI tool, and this tool is not usable without having to buy a license. Is this correct, that I need at least the package Essentials to use CLI and therefore the frames?

  Thank you

  This is the API vCLI,... which is limited read-only in the free version. However, you can connect to the console (or ssh) directly to execute the necessary commands.

• Broadcom 57711 + ESX/ESXi 4.1 + Jumbo frames

  Having a few problems getting Broadcom 57711 NIC working on ESX/ESXi 4.1 with MTU 9000.

  ESX/ESXi 4.0 U2 I have no problems to do and work MTU 9000 and I can push our strong enough EQL PS6010 SAN get 550 000 kbit/s with e/s meter runs inside 4 x VM.

  I read the documentation and found that an MTU of 1500 is supported only for the NIC in ESX/ESXi 4.1 57711. It has somethig to do with the fact that these cards have hardware iSCSI unloading, there is additional iSCSI adapters that appear under the storage adapters heading 4.1 hosts.

  I everything configured properly with 1:1 binding maps iSCSI network to ports VMK iSCSI with an MTU of 1500. When configured, this is the max that I can get out the SAN is 280 000 kbit/s. If I try the same process using the virtual machine a MTU of 9000 / host appears to stop responding.

  While I understand that it is a limitation of 1500 when using iSCSI NIC hardware I am unable to get the iSCSI Software to work with a MTU of 9000 on ESX/ESXi 4.1. If I try the software iSCSI using a MTU of 9000 of the VM / host appears to stop responding.

  Is also a limitation, or am I missing something.

  Is there anyone else out there has the same problems as me?

  Looks like a CD to update the Broadcom Driver (1.60.50.v41.2) was recently published in the area of downloads/drivers & tools vsphere.  I have not tried yet, hopefully, it will solve this problem.

• VMware ESXi4.1 with Jumbo Frames on iSCSI (how to install?)

  Hello

  I've read various articles relating to ESXi 4.1 and frames. They all pretty much say the same thing. I'm having some trouble understanding step 3 in the section "Creating a Jumbo Frames - enabled VMkernel interface" in the link below. Could break you the order for me?

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1007654

  Step 3 says: to create a VMkernel connection with Jumbo Frame support, run the command:

  esxcfg-vmknic - a-i

  My stacked switches cisco 3750G are configured for frames.

  Thank you all. This is my first post.

  Mike

  Assuming you want to create a vSwitch separated with NIC dedicated to iSCSI traffic, you should do this:

  1.) create a new virtual switch, i.e.

  esxcfg-vswitch - an iscsi switch

  2.) enable Jumbo on this virtual switch, i.e.

  esxcfg-vswitch - m 9000 iscsi switch

  3.) create a port for the VMkernel module group

  esxcfg-vswitch - a GRPE-iscsi iscsi-switch ports

  4.) create VMkernel. You must specify an IP address for use with the VMkernel, and a network mask and the MTU size, i.e.

  esxcfg-vmknic - a-i 192.168.100.1 - n 255.255.255.0 m 9000 iscsi-portgroup

  5.) associate a physical NETWORK card with the new switch, i.e.

  esxcfg-vswitch - L VMNIC5 iscsi switch

  You must run the command-line jumbos steps since there is no GUI Option - at least none that I'm aware off the coast.

• The e2000 wireless router does support jumbo frames?

  I can't find (unless I missed it) and in the e2000 on how documentation set sizes of frame of reference.  Is that supported?  If so, what are the steps?

  A fact important is jumbo frames are not compatible at a speed lower than 1000 Mbps

  I think that Linksys E2000 already has Gigabit Ethernet ports.

  And I think that you can change the size of the image on the properties of the Ethernet adapter if the card is a Gigabit Ethernet card.

• SGE2000 extended frames support

  All switches Cisco/Linksys line, why the SGE2000 single gigabit managed that is pass has all kinds of great features including some features of routing layer 3, but does not support true Jumbo Frames?  It is only supported for so-called "mini jumbo frames" 1600 bytes, which is little about as useful as... Well, he is a polished community, so I'll just say it's useless.

  Cheaper switches are supported 10K or 9K jumbo frames.

  The SGE2010 supports 9K jumbo frames.  The SGE2010 is supposed to be the 48-port version of the SGE2000.

  Are there plans to include frames jumbo 9K (or bettter) in a future update for the SGE2000?  Are there any plans even to update the firmware of the SGE2000?

  SGE2000 supports jumbo frames up to 10K today. In fact, the frames extended up to 10 K is supported on all Small Business Smart and Managed Gigabit switches.

  We will have the datasheet corrected - sorry for the validated information.

  Thank you

• Jumbo frames, change the MTU size without VM guest tension

  I'm trying to disable jumbo frames, specifically to change the size of the mtu to 1500 (instead of 9000) in vcenter on some hosts. Some hosts run esxi 4.1, others are running esxi 5.0. I wonder if it is absolutely necessary to turn off the virtual machines that are connected to the iscsi san network while making this change, or is it relatively safe to make this change, while VMS are running.

  Each VM has active multipathing, 2 vswitches with 1 NIC associated with each.

  I know how to make the changes, regarding my questions whether it is possible to safely make changes while VMS still access the SAN.

  Yes, it is something that I do in my lab quite frequently without using maintenance mode. Memaad notes, maintenance mode is always preferable to avoid unnecessary risks, but it's finally to you.

  See you soon.

• Jumbo frames based on VI3 3.5 / iSCSI initiator of material?

  Hello

  Apologies if this has already been posted. If so please point me to the thread, but I just wanted to confirm with you guys jumbo frames based on VI3 3.5.

  As much as I know frames are not taken in charge for software iSCSI but it is supported for the hardware iSCSI initiators but please correct me if I'm wrong. Now what hardware initiator you recommend for jumbo frames?

  Thanking you in advance,

  Saludos,

  Jose Maria Gonzalez,

  In ESX 3.5, 10 gigabit Ethernet and jumbo frame are NOT supported on storage traffic (for example, the software initiator).

  In ESX 4 are supported.

• iSCSI Flow Control vs Jumbo Frames

  It seems with my setup (HP 1800 - 24G switches) I'll have to choose between two frames of flow of GOLD for iSCSI san access control. I am running of frames with a MTU of 9000 bytes. Enabling flow control in addition to yields close to zero rate transfer jumbo frames, so I guess that its not supported by ProCurve 1800-24 G.

  Which option would you recommend to improve the performance of a 2 esx Server (HP DL380G5 ESX 3.5 U2), 1 san installation (HP MSA 2012i, two controllers)?

  Virtualized applications include databases (SAP, Exchange) aswell as moderate use fileserver (actions of the user, company documents).

  I have read other threads on this topic but did not come to a clear conclusion.

  Best regards, Felix Buenemann

  the 1800-24 has a size of 500KB packet buffer.  The specs don't say if this is by port or chassis however since 1800-8A 144KB of buffer space I guess it's chassis, it is not very good news for iSCSI.

  If you have not enough space buffer per port, you can run with a loss of images during periods of high flow.  Loss of images means that TCP will re-transimt the framework and which is slow (compared to normal operation).  I would choose allow control of flow on Jumbos, flow control indicate the end device to stop sending framesuntil the switch has had time to process these images.

• Airport Extreme Gigabit Ethernet and Jumbo frames

  Hi all.

  Can anyone support me kindly about Gigabit Ethernet & Jumbo Frames with Airport Express?

  I currently have and use a 5th generation Airport Express and you want to buy the QNAP TS - 453 Pro NAS. In any implementation of storage NAS, Gigabit Ethernet, the frames extended as matching Ethernet card well, are all very important to achieve broadband performance, so my questions are:

  5th generation Airport Express

  
  

  • Are the NETWORK Gigabit NIC Ethernet card?
  • It also works with extended frames (QNAP NAS supports 4074, 9000 and 7418 bytes for MTU)?
  • QNAP can trunk NIC (if more then one) with the following options:
    • IEEE 802.3ad (dynamic link aggregation)
    • Balance-tlb (Adaptive Transmit Load Balancing)
    • Balance-alb (Adaptive Load Balancing)
    • others (mainly for failover)

  Is 5th generation Airport Express enough or should I think about moving to the 6th generation?

  Thank you.

  You mix up the terminology... Express and Extreme are totally different.

  The title is correct... Extreme... your question text replaces by Express... they are only 10/100... and gen only 2 of them.

  Any airport extreme Gen2 - Gen6

  Use the Gigabit ports.

  Do not support jumbo frames

• CRIO-9082 Jumbo frames

  Hello

  Is it possible to activate the Frames/packets lying on a cRIO 9082?

  Thank you

  PJ

  Do you use the 9082 with installed Windows or real-time? It makes a difference, because it supports jumbo with Windows frames, but does currently support installed with LabVIEW RT jumbo frames.

• EqualLogic SAN and Jumbo frames

  I can't get the jumbo frames to work on our Equallogic PS6000.  We have the following configuration PS6000-> Dell PowerConnect 6248 (bunk)-> Windows 2008 Server.

  The network cards on the SAN has been set at 9000 MTU, ports on switches are set to MTU 9216 and the NIC on Server 2008 is fixed to 9014 with active RX & Tx flow control.

  When the server connects to the SAN, newspapers account connection iSCSI target to the initiator "172.21.X.X:3260, iqn.2001-05.com.equallogic:0-8a0906-xxxxxxxxxxx-23a001a955452af6-server1" ' 172.21.X.X:49156, iqn.1991 - 05.com.microsoft:server1' managed, using the length of the standard framework.

  When I ping the SAN of Server 2008 with a shitload of 8972 bytes, it works very well.

  C:\Users\system>ping 172.21.x.x f-l 8972
  Ping 172.21.x.x with 8972 bytes of data: reply from 172.21.x.x: bytes = 8972 times<1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="">

  Why 8972?  Told that some genius on the internet.  Any help would be greatly appreciated.

  Well we got it to work.  On Server 2008, we have Broadcom and Intel network adapters.  For our tests, we were just using the Broadcom NIC.  Properties Advanced NETWORK adapter, we initially have the value package Jumbo 9014 and it did not work.  So, we opened the Broadcom Advanced Control Suite that came with the NIC and searched and found that there are two parameters that need to be addressed.  There is a jumbo packet definition which has been set at 9014, which is what we wanted it in the advanced NIC Properties.  There is another parameter, MTU, which can be seen on the advanced NIC Properties.  It has been set at 1500.  Once we define to 9000, frames jumbo started working.  We then uncabled Broadcom NIC and wired the card NETWORK Intel and the value of frames 9014 on advanced network adapter properties.  Once we have that frame has worked on this NETWORK adapter, no other measures were needed.  If it's working now.  Thanks to everyone for their help.

• How do I configure jumbo frames

  PC 3548p

  Could not find orders for frames / mtu setting?

  want to set overall n switch?

  I don't see any mention in the technical specifications for the P switch 3548 it supports Jumbo frames.  The 5500 series is the first model to offer the frames extended as a supported feature.

  Thank you

• Jumbo frames

  I want to know the general thoughts on enabling Jumbo frames on my 5548 (stacked 4).  I do not use frames now on any device, but I'd like to in the future.  There has traps enabled on my switches Jumbo frames?  These stacked 4 5548 are my only switches of companies, all servers, devices and clients are running.  Thank you!  -Mark

  Here's a great article discussing the Need To Know: Jumbo frames in small networks

  www.SmallNetBuilder.com/.../30201-Need-to-Know-Jumbo-Frames-in-Small-Networks

  In general the frames are set up when connecting a switch to a storage device.  You can get a good idea if you've addressed this topic in the Forum of storage.

  Hope this helps,
