Introducing VMFS 5: What you need to know in a nutshell – vSphere 5

VMware

It?s new, and it?s good :) VMFS-5 increases limits (without increasing extents) to 64TB. It enables 2TB+ RDMs. It uses a common allocation size of 1MB. It increases the small block allocations available for total use. It is a dependency for SCSI UNMAP It uses the VAAI HW accelerated locking more extensively. Be aware: While it can non-disruptively be upgraded from VMFS-3 to VMFS-5 - if it were my environment - I would tend to create new datastores and svmotion.

How to Install VMware Tools in CentOS 6.4

Linux, Video Tutorials, Workstation

VMware Tools is an optional, free set of drivers and utilities that enhances both the performance of a virtual machine’s guest operating system and interaction between the guest and the host. From time to time I find clients have not installed the VMware tools in their virtual machine’s (VM) operating system. Although the guest operating system can run without VMware Tools, you lose important functionality and convenience. Related Video: https://www.youtube.com/watch?v=pO7iZbuTYJU

Installing CentOS 6.4 in VMware Workstation 9.0.2

Linux, Video Tutorials, Workstation

What is CentOS? CentOS, which stands for the Community Enterprise Operating System, is a distribution of the Linux operating system based on Red Hat Enterprise Linux (RHEL). It is currently the most popular Linux distribution for web servers. CentOS uses the Red Hat source code base to create a product similar to RHEL. Unlike RHEL however, CentOS does not require a paid subscription. In January 2014, Red Hat announced that it would sponsor the CentOS project. As the result of these changes, ownership of CentOS trademarks was transferred to Red Hat. Related Video: https://www.youtube.com/watch?v=pO7iZbuTYJU

Video Tutorials, vSphere

Since vSphere 5.1 U1 it’s possible to install vCenter Server on Windows Server 2012. Also a Microsoft SQL 2012 is supported as an external database.

vSphere 5 ? New High Availability Agent ? FDM

VMware

Another new feature in vSphere 5 is the way it?s handled the HA process. There is no more AAM agent like in vSphere 4.1. Instead, there has been a new agent introduced which is named FDM ? Fault Domain Manager. The Primary/Secondary concept with 5 primary nodes which has been known in vSphere 4, is gone. You no longer needs to worry not to loose all those 5 primary nodes at the same time ?. and loose the HA functionality for the rest of the cluster. Now there is only one agent in the cluster which plays the role of Master. The agent is called FDM ? Fault Domain Manager. One host takes the role of Master. The other agents on other hosts plays only roles as a Slaves, and…

Design Best Practices for VMware vSphere 4.1 and NetApp or EMC Storage

VMware

Best Practices for VMware and Storage The best flexibility comes from a combination of VMFS and NFS Use NetApp or EMC vCenter plug-ins to automate your storage vendor best practices Use Multiple NFS datastores and 10GbE ( 1GbE requires more complexity to address I/O scaling due to one data session per connection with NFSv3) Avoid RDMs, use VMFS pools or NFS pools Make the VMFS and NFS datastores big Use SIOC if you have vSphere 4.1 or later ( Even if you do not use shares, it will ensure no VM swamps the others) Exception: Create planned datasore designs rather than having big pools for larger IO use cases. Oracle, Exchange, SAP etc.
