vSphere: обеспечение катастрофоустойчивости

Understanding vSphere Disaster Recovery/Avoidance options – Part I
Understanding vSphere Disaster Recovery/Avoidance options – Part II (understanding EMC VPLEX partition and VM HA) "TODAY there’s no way for VPLEX (or VM HA for that matter) to differentiate a “failed inter-site communication link” (which happens disturbingly often) from “one site is a smoking hole” (which happens more rarely).   Other options for this sort of thing are 3rd party “voters” (which have some sort of “keepalive” signal to the two sites – though 3rd part voters can add as much complexity as they eliminate)."

Service Console - ESX Server Firewall Commands

The firewall built into ESX server uses iptables, the very commonly used Linux firewall. However to create the rules another esxcfg tool is used, which is esxcfg-firewall.

To list the services currently controlled by the firewall:

esxcfg-firewall -s

To list the firewall rules:

esxcfg-firewall -q [servicename]

esxcfg-firewall -q

Enable a service:

esxcfg-firewall -e [servicename]

esxcfg-firewall -e sshClient

Disable a service:

esxcfg-firewall -d [servicename]

esxcfg-firewall -d sshClient

Open a port:

esxcfg-firewall -o 465,tcp,out,out-smtps

Close a port:

esxcfg-firewall -c 465,tcp,out
