Seminar: Disaster Recovery met Hyper-V replication in Windows Server 2012

Bent u op zoek naar een Disaster Recovery (DR) oplossing zonder de hoge kosten zoals bij SAN replication komen kijken? Dan is Hyper-V Replica iets voor u. Deze nieuwe feature is bedoeld voor klein- en midden-MKB. Het is een storage log asynchrone opslagtechniek waarbij iedere 5 minuten alle wijzigingen van een Virtual Machine worden gerepliceerd naar de Disaster Recovery locatie. Hiermee heeft u een goedkope Disaster Recovery oplossing waarmee hooguit 5 minuten aan data verloren gaan. U kunt deze techniek ook gebruiken wanneer u geen Disaster Recovery locatie heeft, want de replica kan ook naar de public cloud!!

NUMA support in a virtual machine

• Projects NUMA topology onto a virtual machine

• Allows guest operating systems and applications to make intelligent NUMA decisions

• Aligns guest NUMA nodes with host resources

Non-Uniform Memory Access

Guest NUMA topology by default matches host NUMA topology

vNUMA node A vNUMA node B vNUMA node A vNUMA node B

NUMA node 1 NUMA node 2 NUMA node 3 NUMA node 4

• Multiple modes: switch dependent and independent

• Hashing modes: port and 4-tuple

• Active/active and active/standby

Copies of the configuration file and

saved state are copied to the destination

Validation occurs on the new host

If required, “fix it” wizard is used for repair operations
