Create a Folder in c:\VMware_Backup

• To create a folder in windows is very easy, right click on c: and create a new folder VMware_Backup. You can choose whatever location you want, in this case it is c:

Create a scratch Partition in ESXi host

• Login to ESXi host using Putty

• Type commands

cd tmp

mkdir scratch (* If this folder exists already, you don't need to create one)

cd scratch

mkdir downloads (* If this folder exists already, you don't need to create one)

Now open up vCli

Hit Ok

One requirement

Go to ESXi Firewall and enable syslog ports on it

Now see you Syslog server Location for files, you should see some files on Data folder under syslog Server

How to convert Disk throughput and Block size into IOPS
How to convert IOPS and Blcok size to throughput

Formula

To calculate IOPS

IOPS = (MBps throughput / Block Size) * 1024

Explanation:

Throughput is how much a disk can write per seconds
Block size is how much one IO can write per seconds
1024 is given from the formula to conversion like KBps or MBps

Example:

• What number of IOPS should be used with Storage I/O Control to limit disk throughput to roughly 10MBps if the guest application writes 64KB blocks?

1. IOPS= (10 / 64) *1024

         = 160 IOPS


To calculate Throughput

Throughput = (IOPS * Block Size) / 1024

Example:

• What number of IOPS should be used with Storage I/O Control to limit disk throughput to roughly 10MBps if the guest application writes 64KB blocks?

1. Throughput = (160 * 64) /1024

                           = 10
