Announcing the vSphere 6.5 Update 1 Security…

I am really pleased to announce the availability of the 6.5 Update 1 Security Configuration Guide (SCG). Normally a new guide is done only for numbered releases and not updates but the number of security updates that have made it into 6.5 Update 1 has warranted this SCG release. Also, we want to show how The post Announcing the vSphere 6.5 Update 1 Security Configuration Guide appeared first on VMware vSphere Blog .

HCI Bench – vSAN performance tool – Part 3: Tests and Results

Tests

Once you hit the “Test” button you can go watch some movies. It’s take a time depend on your HW. For me it was couple of hours.

  • It starts with VM deployment

  • It will create bunch of VM’s (each 4vCPU, 4GB of RAM, 9xHDD (total 250GB))

Testing was done by using Vdbench VM with input argument “-fvdb-8vmdk-100ws-4k-70rdpct-100randompct-8threads

Results

Tested VSAN configuration:

  • 4x Node configuration with 10gigabit connection
  • VC build: VMware vCenter Server 6.5.0 build-7515524

Each ESXi host:

  • Build: VMware ESXi 6.5.0 build-7388607
  • CPU: Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz ( Packages: 2, Cores: 20 )
  • Memory: 256 GB
  • Server vendor/model: Dell Inc. PowerEdge FC640
  • VSAN Disks:
    • SSD: Local TOSHIBA Disk (naa.58ce38ee2000c0ad)
      • TOSHIBA PX05SMB080Y
      • 800 GB
    • SSD: Local TOSHIBA Disk (naa.58ce38e06c8a274d)
      • TOSHIBA PX05SRB192Y
      • 1920 GB
    • SSD: Local TOSHIBA Disk (naa.58ce38e06c8a26fd)
      • TOSHIBA PX05SRB192Y
      • 1920 GB
    • SSD: Local TOSHIBA Disk (naa.50000397cc89cd79)
      • TOSHIBA PX05SMB080Y
      • 800 GB

Some time ago, I wrote about which policy changes can trigger a rebuild of an object. This came up again recently, as it was something that Duncan and I covered in our VMworld 2017 session on top 10 vSAN considerations. In the original post (which is over 3 years old now), I highlighted items like […] The post Which policy changes can trigger a rebuild on vSAN? appeared first on CormacHogan.com .

HCI Bench – vSAN performance tool – Part 1: Installation

What is HCI Bench

HCIBench stands for “Hyper-converged Infrastructure Benchmark”. It’s essentially an automation wrapper around the popular and proven VDbench open source benchmark tool that makes it easier to automate testing across a HCI cluster. HCIbench aims to simplify and accelerate customer POC performance testing in a consistent and controlled way. The tool fully automates the end-to-end process of deploying test VMs, coordinating workload runs, aggregating test results, and collecting necessary data for troubleshooting purposes.

HCIBench is not only a benchmark tool designed for vSAN, but also could be used to evaluate the performance of all kinds of Hyper-Converged Infrastructure Storage in vSphere environment.

HomePage:
http://labs.vmware.com/flings/hcibench

User Guilde:
http://download3.vmware.com/software/vmw-tools/hcibench/HCIBench_User_Guide.pdf

Prerequisites

  • vSphere 5.5 environment or higher with vCenter (doesn’t support deployment on a standalone ESXi host).
  • Good to have DHCP on VLAN where the benchmark VM will be deployed.
  • vMotion configured

Installation

  • Select name and location for your VM

  • Review details

  • Accept license agreement
  • Select storage. Put it outside the VSAN datastore

  • Select destination network
    If there’s no DHCP Server on the VLAN which Vdbench client VMs will be deployed on, or the VLAN for Vdbench client VMs can not be routed from the Public Network, map this Network to the VLAN and Enable DHCP Service in the Web UI if needed

  • Customize the VM. As I am using DHCP in my LAB so all Network fileds are empty. And at the bottom enter your password for root.

  • Review configuration data before deployment

  • Hit “Finish” and watch progress in “Recent Tasks”

5 Ways to Change Hostname of your ESXi host

This post is a quick recap of different ways to change a hostname of an ESXi host. There are different ways we work and different tools we use. Not every time we have the chance to use the tools we want, or we have an access directly to the server room or to the console.

VMware Capacity Reporting Part IV: VVol…

Storage capacity reporting seems like a pretty straight forward topic. How much storage am I using? But when you introduce the concept of multiple levels of thin provisioning AND data reduction into it, all usage is not equal (does it compress well? does it dedupe well? is it zeroes?). This multi-part series will break it … Continue reading VMware Capacity Reporting Part IV: VVol Capacity Reporting →

VMware Cloud Foundation – Technical Overview…

See how VMware Cloud Foundation brings together the core SDDC building blocks of compute virtualization (with VMware vSphere), storage virtualization (with VMware vSAN) and network virtualization (with VMware NSX), together with the automation capabilities of the VMware SDDC Manager, into a new unified SDDC platform that provides a vastly simplified SDDC experience.
