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

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.

vSphere 5 ? New High Availability Agent ? FDM

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.

VMware vSphere 5 features a new ESXi firewall

VMware
VMware vSphere 5 features a new ESXi firewall that you can configure though the vSphere Client or command line. The addition brings a feature to ESXi 5 that was previously found only in the recently discontinued ESX hypervisor. VMware argued that ESXi didn't require a firewall, because the lightweight hypervisor had hardly any services or ports open, leaving it with almost nothing to attack. I believe VMware added a firewall to ESXi 5 for few reasons. With a firewall, ESXi 5 isn't missing a notable feature found in the old ESX Server. Also, a firewall signals to customers and partners that VMware is committed to security. And finally, vSphere 5 is just as secure as before, if not more so. Five things to know about the ESXi 5 firewall It?s…
