Network of twinning with Port trunks to support the host ESX VShere 4 with several NIC for load balancing across a HP ProCurve 2810 - 24 G

We are trying to increase production of our ESX host.

ESX4 with 6 NIC connected to HP Procurve 2810 - 24G 2 ports; 4; 6; 8; 10 and 12.

The

grouping of parameters on ESX is rather easy to activate, however, we do not know

How to configure the HP switch to support above connections.

Pourrait

someone please help with a few examples on how to seup the HP switch.

Help will be greatly appreciated as we continue to lose tru RDP sessions

disconnects.

Best regards, Hendrik

Disabling protocols spanning-tree on the Procurve ports connected to the ESX host is going to promote a recovery more rapid port. Similarly, running global spanning tree is not recommended if you mix some VLAN iSCSI and data in the same fabric (i.. e. you do not want a STP process to hang storage IO). Spanning tree on your switches, look PVST (or Procurve BPMH) to isolate the STP VLANs unique events.

In regard to the load balancing is, by default (route based port ID) value algorithm requires less overhead on the ESX hosts. You may not use LACP on the Provurve the lack of facilities LACP ESX. You must use "route based on the IP hash" sideways ESX and 'static trunks' on the side of Procurve. Unless you have specific reasons why your network need loads this configuration, I'd caution against it for the following reasons:

(1) IP hash requires thorough inspection of packages by the ESX host, increasing CPU load as load package increases;

(2) the static configuration puts switch physics rigid and critical ESX host port mapping. Similarly, groups of ports all will fail as the Procurve batteries for management only and won't be on switches 802.3ad circuits Group (i.e. all ports of a group of circuits must be linked to a single switch) - this isn't a limitation of the port ID routing;

(3) K.I.S.S. love port ID mix of port ID, beacon probe and failover on the port assignments you will get segregation of the raw traffic without sacrificing redundancy - even through switches.

I hope this helps!

With forms 10g server load balancing
Hello

I have a client who is just now dealing with a migration from a platform of client-server 6i (using Terminal servers) to a platform of web forms 10 g with several application 10 g standalone servers.

In the end, customer wants to activate load balancing in order to have some manage to each application server workload.

The idea to accomplish is to have a hardware load balancer. The customer has already a CISCO CSS 11503 SSL.
Is there a documentation where I can check more info on compatibility/configuration for this architecture.

Thank you for your attention.

Kind regards
Pedro Ribeiro
You can check this doc link: [http://download.oracle.com/docs/cd/B14099_19/hpux.1012/install.1012/install/toc.htm]
It say everything and anything mention on a load balancer, but I'll try to keep the research.

NAT network between the host ESX with DVS

Hello.
In my test of vSphere 4, I have two ESX hosts. I want to share an IP address between all the virtual machines on these two ESX hosts. In this regard, I have a virtual machine that acts as a NAT router. This virtual machine has two network that is connected to each their own vNetwork Distributed Switch connection. We have a physical NIC (on each ESX host) which has the Internet connection. The other has no physical network connection.
To test if it works I created a VM test on both ESX hosts. The system works on the virtual machine that is on the same ESX host as the virtual machine that acts as a NAT router is located, but not the virtual machine on the other ESX host. The other VM have no contact with the router and receives no DHCP data.
Any suggestions? I know I did something wrong because DVS is new to me, but I really want this to work.

Hello

That ends up being a vNetwork design more than anything even with vDS. For example, if you have a NAT that works for all your hosts you would then have a NAT virtual appliance such as:

PSwitch external network <->Teddy <->vSwitch <->vPG <->NAT VM <->vPG <->vSwitch <->Teddy <->network internal pSwitch

Now the vSwitches in the above can be traditional vSwitches or vDS' the key is that the "seconds" vSwitch must be connected on the same vSwitch on all other hosts, so it has an uplink to a physical switch that is also connected to all other hosts. vDS does NOT lighten your vNetwork is the need of cable to allow the communication of the VM.

The VM NAT can move from host to host as long as there is communication to this virtual machine on each host on each network in this case, the external network and internal.

Load balancing across the NETWORK interface card

Hello
Our ESX Server's NIC six, two for SAN, one to the dedicated Service Console and three for the virtual computer LAN traffic. I noticed one thing look in the performance tab in VC, is that all LAN traffic seems to go on one of the three the NIC and the other two are practically inactive.
If I look at the network configuration for the vSwitch those with three cards network, grouping of NETWORK cards is set for 'road based on the original virtual port code '.
Can anyone advise how to get a more 'democratic' usage of the three NETWORK adapter?

As seen on http://www.eqlforums.com !

How many virtual machines you host? With the load balancing algorithm you have selected (default), traffic is balanced to the vNIC level (i.e. all traffic from a given vNIC always through the same bear). This is the case for all, but the IP hash algorithm, which requires you to 802.3ad static port aggregation on your pSwitch. In most cases, there is no need to worry about the use of bear - if it's a GbE NETWORK card, you're probably not close to push the limits.

Connection to the AOP with several NIC data store

I have a situation where I need to have the computer that is running the tiara to be connected to two different networks. I have two NIC installed in the machine, NIC A and B NIC, we will call them. The reason for this is that I use Diadem to access the server on a machine of AVL PUMA AO. If I connect to the local network PUMA, PUMA sometimes breaks down, probably something to do with the IP address. So PUMA has need to be on a network that is not a router. My tiara computer must communicate with PUMA, as well as with local shared drives on our corporate network.

In any case, I have the company LAN hung on A NIC and hung on NIC B PUMA network. Tiara fails to connect when the two networks are connected, but connects to the data store no problem when that network PUMA is hung. Any ideas how to solve this problem? It seems tiara is looking for NIC - A instead of NIC B, as appropriate.

For reference, when the two NIC is connected, I can access other than readers, and separate computers to ping on both networks, without problem, is not a connection problem.

Any help would be appreciated.

-Russ

I guess poth NIC have different IP.

-Did you use IP instead of the server name.

-Do you use RPC or CORBA to access the PUMA Server?

-What version of DIAdem.

You can create a log file when the connection has failed?

With Adobe ID, is it possible to have a single account, but with several IDs for access to limited features?

I find it hard to manage all the needs of our unique Adobe ID is it possible to have a configuration similar to the following

With view 5.1 load balancer

Hey all,.
I have a question about to lift our load balancing program and perform in our view environment 5.1. I followed the article KB 2020913 to get our servers view running with SSL certificates. I'm doing our load balancer in place and I keep getting errors in SSL certificate. Here is a brief summary of our facility. I have two servers to view (VCS1 and VCS2) connection with our internal certificate authority SSL certificates. There is our program of load balancing. When you use VMware View Client and go to the view.company.com address of the load balancer, I get "pipe in the certificate name is invalid or does not match. I click on 'See the certificate' and it is to show the certificate of one of the connection view servers. A I mess up something with the installation program, or have I missed an obvious solution? Any help would be appreciated.
Thank you
-Kyle

Hello

It is the expected behavior. With SSL, the certificate name is checked by report specified by the client host name.

There are two ways to deal with this. If you are using certificates with another subject of your load-balanced alias name, it all will work.

for example if you have some certs on each connection to the server (or the Security Server) with the names cs1.myco.com and cs2.myco.com but customers do you think users will connect using a load-balanced alias view.myco.com, then by ensuring that each cert has another name of subject of view.myco.com then the hostname match control work.

See KB. VMware.com/kb/2006751 for more information.

twinning with several accessories

Hello

I intend to buy a bluetooth headset to pair with my Z3 Compact Xperia, but I already have a SmartBand speech, which is usually connected to my camera. So, is it possible to link the two headphones (or maybe some bluetooth speakers, too) and my SmartBand with my Z3C at the same time or just one at a time?

It would be great, if someone knew the answer.

Thank you very much!

You can pair the phone with a bluetooth headset and SmartBand talk. Only one can be connected to both good. So to use your bluetooth headset you must disconnect your SmartBand speech first.

Need to powershell script to gather the host ESX Info network

Hello

I need two scripts powershell to collect two types of information about the ESX host network.

1. information vNIC -& gt; information on the vmnic (physical ESX host network adapter) connected to vSwitches.

(Example) output expected:

2. Portgroup information

PortGroup | vNIC (s) with active / standby | PCI slot of vNIC (s) with active / standby | Physical switch with port number

Expected results (example):

Service console | vmnic0 (a) : (s) | 01 vmnic1: 00. 00 (a) : 02:00. 00 (s) | abcd-123 [GigabitEthernet10/10] : xyzf-7890 [Gigabitethernet11/11]

Please note if CDP is not active, then in the field of physical switch values can contain "CDP is not enabled"

Thanks in advance!

Noticed that the two threads under became a little mixed in the script.

This is the script with the devIds with the indication of the active / standby.

How to load the program on my new computer. I have the DVD disc. How can I got to talk to someone at Adobe? Don't they have any live support?

Hi wayneharder,

Use of the download link for Photoshop CS6 Extended below.

Download Adobe Creative Suite 6 applications

Once the application is downloaded and ready to install it, need you the serial number to activate it.

If you already have a copy of one of them, then it's fine, otherwise check out the link below to find your serial number registered.
