DataCore DataCore-V with ESXi, vSphere 4.1 iSCSI running
I have looked everywhere and come short on my problem, if this is a problem? In the past, I have always connected all ESX / ESXi host through corn and now I work more with iSCSI. I always try to get a handle on it. It's one thing to read about iSCSI and he put in place of the other. OK, now that I have that came down my chest, here is my question.
Should the two iSCSI connections in DataCore-V show ready if I have both connected?
Here's a high level race down the environment.
1. a single node of DataCore
2. a single ESXi host
3. the two dual iSCSI ports
4. on the DataCore node, only one port shows ready
5. on the ESXi host two connections show connected
Help, please
Hello
To meet ask you: It will say connected when a host 'iSCSI IQN init' is connected, simply because he says tell-connected does not necessarily mean that the 'network' is down... The host/s are not, cannot connected. (or none have been configured).
More information about your configuration will be useful, however check over the info / recommendations below (Simple config)
1. you set the "Port" Type for the two iSCSI ports on the DataCore for "FE" "Front End" Server?
2. you have defined two separate IP addresses for the iSCSI on DataCore iSCSI ports ports?
3 for simplicity on the ESX host, you have two distinct vSwitches for iSCSI with a NIC each with a vmKernel configured with IP to talk to the DataCore "target Ports.
Therefore to confirm you can test the interfaces between them... now connect connection to DataCore target ports
If you use software iSCSI Init, enable it on the ESX host... then you will need to "Discover" ports "targets" (static or dynamic)
Once you add the two DataCore target Port IP please make sure that you "Login" for them to the ESX host. (BOTH)!
If it worked, now you can join the 'Host' ESX in DataCore-V interface and assign the "iSCSI initiator" (from the ESX host) to it. (Only will be there for iSCSI Software...
Now, remember, there is that a single iSCSI Software initiator, the important thing is to make sure this initiator is recorded in the TWO ports of DataCore target... Check the DataCore-V 'Remote Ports"tab on each port of 'target' for the IQN of the ESX host name.
NOTE: DataCore servers don't support not multiple sessions to the same IQN to a vSphere Host to a unique DataCore iSCSI Target
XXXXXXXXXXXXXXXXXXXXXX
Also, please see best practice information about DataCore for your settings of the NETWORK adapter on the server of DataCore.
Let us know how you and perhaps give a bit of monitoring more than info...
Best regards
Bernie.

Having problems with ESXi/vSphere Client Network
First of all, I apologize if it's thread is in the wrong section.
I recently installed ESXi v6.0.0 in VMware Workstation 12.0 trying to familiarize myself with ESXi as I recently graduated and I forgot most of what I learned from the class I took.
Then, ESXi installed smoothly and was very painless.
Then, I tried to create a virtual machine. It's when things are messy. I can't understand why, but I don't get any network connectivity after obtaining a DHCP address to all within the virtual machine, in addition to being able to ping the host ESXi itself.
First of all, networking is like so:
10.10.10.1 router/gateway
10.10.10.254 DHCP, DNS, server, VMware Workstation files 12
10.10.10.250 ESXi host
10.10.10.244 ESXi reviews - Windows 7
Googles DNS 8.8.8.8
VMware workstation 12:
AMD FX-8350
Intel Corporation 82574L Gigabit Network Connection
NVIDIA Corporation GF119 [GeForce GT 520] (rev a1) - However, not allowed to work with VMware VMware or xvnc throws a fit to this topic

Looking for advice on my lab with ESXi 5 free
Hi all
I would like to know if I need a license to just virtualize machines in my scenario.
My goals:
- All virtualized Machines, I will not use virtualization features, I want just the availability virtualize my machines, I don't care management or vmotion. I know that in a production environment is not a good practice, but like I said, I just want a maximum of my machines.
Here I show my laboratory structure:
Servers:
- I have 2 servers with the following configuration:
- Intel Xeon 2630 V2
- Motherboard S2600CP2
- 64 GB OF RAM
- 4 1 TB HDs
- 1 SSD 240 GB HD
- 2 10/100/1000 integrated network in the motherboard cards
- I have 1 server with the following configuration:
- Intel Xeon 1356 - E5 07v2V2 24
- Card mother Intel S2400SC2
- 64 GB OF RAM
- HD 1 TB
- 2 10/100/1000 integrated network in the motherboard cards
Switches
All the switches used will be of Juniper Networks
- Thorns:
- following 2 switches with port configuration:
- 24 ports QSFP +.
- following 2 switches with port configuration:
- Leafs
- 3 following switches with port configuration:
- 48 SFP / SFP ports +.
- 2 uplinks QSFP + to connect on thorns switches
- 3 following switches with port configuration:
You can see a summary of my lab demonstration at the laboratory of attached file '. '. PNG ".
My doubts:
- Will it take any license of vmware to achieve what I want, even though I won't use it all functionality of virtualization, I want just the infrastructure. I read this link free virtualization with VMware vSphere Hypervisor (ESXi) | United States of America and I think I won't have a problem... What do you think??? Thank you.
WARNING: This is not legal advise and you're not my client. My TAM has confirmed that you can use unlimited ESXi licenses for your current setup without any problems. Please login to the portal of VMware and ask your ESXi unlimited licenses. Don't forget that you will need licenses paid if in the future you decide to deploy vCenter to manage these hosts and use of advanced features such as HA, vMotion. Feel free to ask more questions.

replication between different versions of ESXi vSphere
Hi all
Is it possible to use replication between different versions of ESXi vSphere? the scenario is as follows.
Source site:
vCenter 6
RS 6
Replication Unit 6
5.5 ESXi
The target site:
vCenter 6
RS 6
Replication Unit 6
6 ESXi
I understand that vCenter, SRM and VRA must match and vSphere replication 6 is compatible with ESXi 5 upwards and it is the vSphere host in the source location that replicates on the VRA rather than a host of ESXi target so it should work, but I wanted a certain Yes/No.
Thank you
Definite yes.

Create a local user with the vSphere Client
Hello
I want to create a new user with the permission of readonly. In the vmware documation salon, they say I have to go to the tab local users and groups, but there is no tab with that name.
And sorry for my English I'm not a native speaker.
Hi and welcome to communities,
This tab is visible only when you connect to the ESXi directly with the vSphere Client. You won't see when you connect to a vCenter server.

Storage vMotion possible with ESXi Std Edt or not?
Hi all
We have two implementations of VMware with ESXi Standard edition licenses installed on the two site. A site has vCenter Server Foundation edition while the other has vCenter Server Standard Edition.
The problem is that the site with vCenter Std and vSphere 5 Std doenst allow storage vMotion (see image below)
While, on the other hand, site 5 Stnd vSphere with vCenter Foundation allows storage Vmotion (see image below)
How is it so that vSphere Stndard this edtion of different characteristics in different places?
I had recorded the call and found the solution... VSphere 5.0 and 5.1 gives really different set of features with the same Std license vSphere. Take a look at the link for options available with vSphere 5.0 and 51 below.
1 compare vSphere 5.0 editions
Compare the editions of vSphere VMware for Cloud Computing, server and data center virtualization
VSphere editions 2 - compare 5.1
Compare VMware vSphere editions: managed Virtualization & amp; Cloud Computing
For a test, I used the same Standard edition server with 5.1 key to it has worked well with Storage vMotion Option available :-)

Talha Correia
Hello
You must download and install the client on your computer.
You can find in the download section of the website of VMware vSphere.
It comes to 5.0

Hello.
We have an application on redhat with hight cpu utilization.
For now, we use the server with 4 QuadCore CPU, then 16 core.
We believe the use of virtualization for this application.
I see the standard ESXi license has limitation of 4vCPU...
Can I make a virtual machine with 16 vCPU with ESXi or vmware product?
There's a special permit for this?
Scalability is good? Or it is better not to use vmware for this use?

8 - way SMP is currently the maximum supported by ESX and which will require the product under license (i.e. not 'free' license). There are speculations that this number will 8-way beyone in the next version, but there is no guarantee. Typical applications of virtualization are scale-out, not measure - upward for this reason. However, you can assign only 8 lanes practically in several ways:
1 x 8-core vCPU
2 x 4 vCPU strands
4 x vCPU 2 strands
8 x 1-core vCPU
Use the advanced cpuid.coresPerSocket setting to configure. I have more details about it in my blog:

Reload via Web Services with ESXi?
Is it possible to restart a virtual machine running on ESXi using Web Services? I tried the sample code provided with the SDK, but I get an error. RestrictedVersion.summary. ideas?
Thank you
ARIN
PS. I also tried the scrip poweroff_suspend_vm.pl with the same results.
To use the API or remote CLIs with ESXi, you must have a paid license. If you use the free version of ESXi, you will not be able to take advantage of the APIs or CLIs

Can be used with ESXi 4.0 HP system management tool?
Hello
I'm installing ESXi 4.0 on HP DL380 G4 server and I was wondering if the management of the HP tool system can be installed along side the hypervisor, so I can remotely check the condition of the equipment of the machine.
Anyone know if this is possible?
Thank you
I had little experience with HP SIM, it's been a while. So with ESXi, there is no agent that runs on the host computer, it uses the CIM (Common Interface Management) which is an API that can monitor the hardware and return this information to tell your server HP SIM. For the configuration and use, I recommend looking at HP and the involvement of the HP documents. If you have installed ESXi HP image, then from the point of view host you should be good. You must later have your SIM Server talk to host ESXi and sure he monitors the components you want and alert on it, etc.
Here are a few articles around ESXi and CIM blog:

We currently have a host running vSphere ESX. We also have another license for vSphere with the intention to build this second host soon. Is one of the things I want to start using vMotion, Storage vMotion, and obviously with this second host I can start doing this. My question is, can I do all this with ESXi 4.0 as well? If all I want to do is create virtual machines and have them fast vMotioning between the hosts, this free option will allow me to do? ESXi 4.0 does support vMotion and Storage vMotion?
What drawbacks are with ESXi? I'm looking to save money on licensing costs and put the money saved towards greater SAN storage.
Thank you very much for those who answer with the information!
So yes you can vmotion between both versions.

PowerEdge Raid700 in RD540 with ESXi Thinkserver
Hello
I'll put up a hypverisor 5.5 ESXi update 2 on a lenovo RD540. There is a RAID700 controller.
I use 3 HARD drive in a RAID6 configured with the tool of the bios (Mega RAID LSI)
The server works fine, but I don't see the healthy of the RAID on the ESXi.
I don't see the virtual disk, not the adapter of storage or physical disks. If one lose a disc ESXi does not know, I hear only the PIF from the server.
How can I solve this problem?
If I use the "Lenovo easy start' to install ESXi RAID adapter will be with ESXi?
Thank you in advance.
Concerning

Right now, I'm on the WebBios and I can't find where I can configure it

Could not detect my DPS and hdd with Esxi 6.0
Hello forum,.
I bought a relatively new desktop for my studies of cisco computer. I am completely new to exsi and took notes on the net to install esxi.
In "Select a disk to install or upgrade", I am unable to see the two hard drives.
I have,
CPU Intel I7 - 4790K, motherboard Asus Z97 - has
240GB Kingston SSD
Toshiba 1 TB HARD drive
I tried to format the two hard drive using windows 7 and tried to install Esxi 6, but the two remains undetected.
I tried 5.5 as well but the result is the same.
Help, please.
Thank you.
ESXi is built for server hardware, he may simply not support your disk controller. Since it is a lab environment, you can check if VMware experience before: how to make your unsupported work SATA AHCI Controller with ESXi 5.5 and 6.0 helps build a custom installation image that runs on your hardware.
