Okay, so lots of problems, here....lets take one at a time, and I'll guide you.... lets start with iSCSI.<br />
<br />
What is the NAS/SAN ?<br />
<br />
NFS may be a better choice than iSCSI!

<div>
Hey Andrew<br />
Thank you so much for your help.<br />
My Nas storage Terra &nbsp;4 tb , and Luns are work ,if i connect from my laptop with ISCSI connection
</div>


<div>
i think first i &nbsp;need to learn, configuration ISCSI connection how on esxi :<br />
<br />
how can i plan my ISCSI connection on esxi01 and esxi02?
</div>


<div>
do i need to connect switches: are they correct?<br />
<br />
esxi01:192.168.0.5<br />
vmnic0 --&gt; switch(192.168.0.200) port1<br />
vmnic1--&gt;switch(192.168.0.<wbr />200)port2<br />
<br />
esxi02:192.168.0.6<br />
vmnic0 --&gt; switch(192.168.0.201) port1<br />
vmnic1--&gt;switch(192.168.0.<wbr />201)port2
</div>


<div>
at the moment i try to learn how TRUNK configuration on HP 1820-24G switches. I have read somewhere ,first i need TRUNK connection if i want to use with ESXI servers.
</div>


<div>
<blockquote>
4.ISCSI connection to ESXI , This my big problem at the moment . Do i need to use different IP &nbsp;subnet for ISCSI ? do i need to connect VLAN ISCSI the same portgroup where is all my VMs(VM Network) or do i need to create VM Network 2 ? if yes how connect my VMs on VM Network 2 to VM Network ?<br />

</blockquote>
<br />
I would use a non-routable IP Address e.g. 10.x.x.x or 172.16.x.x. and create a VLAN which you connect network cables to, so it's on it's on VLAN, e.g. 40 - no need to tags of anything, and you will want to connect one interface from each ESXi host server to each switch.<br />
<br />
Okay, I have an article for Best Practice as to how you configure iSCSI.<br />
<br />
You do not use TRUNKS with iSCSI storage, you use two single network interfaces at minimum.<br />
<br />
Please see my EE Article Tutorial, step by step with screenshots<br />
<br />
<a href="https://www.experts-exchange.com/A_9250.html" rel="ugc">HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0</a><br />
<br />
also you will want to enable Jumbo Frames on ESXi, HP Switches and NAS<br />
<br />
<a href="https://www.experts-exchange.com/A_9132.html" rel="ugc">HOW TO: Enable Jumbo Frames on a VMware vSphere Hypervisor (ESXi 5.0) host server using the VMware vSphere Client</a><br />
<br />
all articles are valid for ESXi 5.x and 6.0.<br />
<br />
So that's iSCSI and Bindings.<br />
<br />
Do you need VLANS, and what is going to communicate between the VLANS, e.g. Clients and Servers on different VLANS will not be able to coimmunicate without routing, or Inter-VLAN routing.<br />
<br />
Next create at least a two port STATIC Trunk (NOT LACP - not supported) on each physical switch, but ideally again you will want to connect each ESXi host to both switches to avoid a single point of failure, on that trunk you will want to use Tag VLANS 10,20,30.<br />
<br />
on ESXi, you will then want to add those Tags to networks, 3 virtual machine networks that you create.<br />
<br />
But you will have to think how traffic is going to get from VLAN 10, VLAN 20, VLAN 30 and communicate with each other if required...

<div>
Very nice Artikel. i am so sorry for stupid question,<br />
<br />
I choose 172.16.x.x range for ISCSI VMKernel . NAS IP address should be in this range ? Because at the moment on my network 192.168.0.253.<br />
&nbsp;Thank you for very nice guiede
</div>


<div>
Yes, your NAS will also need an IP Address on your iSCSI storage network.<br />
<br />
You may have options on your NAS to configure different IP Addresses
</div>


<div>
yes ! i did &nbsp;iscsi and i can see LUNs on esxi server. i connected one more network card bought esxi server , now i have 3 cards now . I use 2 for iscsi connection.<br />
<br />
1. Nas IP i did not change 192.168.0.253 ,jumbo is enabled all are switch and NAS<br />
esxi01:<br />
1.VMkernal 1 192.168.0.101 <br />
2.VMkernal 2 192.168.0.102<br />
<br />
esxi02:<br />
1.VMkernal 1 192.168.0.103 <br />
2.VMkernal 2 192.168.0.104<br />
<br />
vlan section on vmkernel not added . do i need ? At the moment I do not know how CORRETLY create vlans on HP 1820-24G.
</div>


<div>
you do not need to add VLAN to iSCSI, just create tags on those network ports in use by iSCSI &nbsp;on the switch to set them VLAN.<br />
<br />
There is no console on the HPE switch, so it's all done via a Web GUI.
</div>


<div>
I am so sorry Andrew , i did not understand what you mean &quot;&nbsp;just create tags on those network ports in use by iSCSI &nbsp;on the switch to set them VLAN.&quot; <br />
<br />
you mean ,i need to create VLAN on switch .example:<br />
<br />
VMKernal1 connected HP switch1 port1 and VLAN 10 Created --TAGGED ,is it correct?
</div>


<div>
and i write VLAN 10 on the VMKernal VLAN ID section.
</div>


<div>
There is NO need to change anything in ESXi for iSCSI storage network. You do not have trunk ports, you are using single ports. e.g. access port.<br />
<br />
You just need to create VLAN Tagged Ports on the physical switch and you do that by selecting the port on the switch and adding it to a VLAN.
</div>


<div>
ISCSI work very quickly Now , IT was never so :)))) thank you
</div>


<div>
i woud like to create 3 x vlans Andrew. <br />
VLAN10 Clients<br />
VLAN20 Servers<br />
VLAN30 DMZ <br />
can you please explain me what do i need to do?
</div>


<div>
I did not belive every thing goes so quick. Many Nights and many days i try ,Now works ! I cant belive it
</div>


<div>
should have posted here first!
</div>


<div>
oh now i Need trunk ! Hmmm i think i need little bite read again HP giuede :)
</div>


<div>
you are right ,i just tried google read
</div>


<div>
oh i think ,i understand ,TRUNK need because i have only ONE REST NETWORK CARD &nbsp;and card must be now where vlan 10 or vlan 20 or vlan 30
</div>


<div>
trunks are normally, two ports on a switch. a trunk port.
</div>


<div>
if i add all my vlans to trunk then u think my previoues &nbsp;ping problem will be gone (windows 10 cleint cant ping to domain controller which are on the same IP range but diffrent vlans)
</div>


<div>
thank you so much for you quick VERY QUICK HELP.<br />
I wish you all the Best.<br />
Till new Problems :))

ESXI configuration with Vlan

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Windows OS

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

Microsoft SQL Server

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
