Disaster recovery solution
Disaster recovery solution for data centers
Disaster recovery solution for manufacturing companies, using server virtualization and redundant storage subsystem.
It may include local network redesign and upgrade, with added redundancy using trunking / physical connections bonding, if redundancy does not exist yet.
Disk data is synchronously replicated over redundant LAN. Optionally, fully automated failover in case of emergency can be implemented using Pacemaker clustering software.
All physical and virtual servers and web and networks services are actively monitored. Monitored data is available through web user interface.
Tools used: Enterprise Linux, DRBD, Archipel, Zabbix, network IEEE802.3ad (LACP) protocol, BIND, Apache, Exim, Courier-IMAP
