As KVM seems more and more interesting, at work we wanted to do a Proof-of-Concept. The KVM hypervisor cluster had to be controlled by CloudStack and also integrate with NSX (formerly known as Nicira). NSX is owned by VMware these days and is one of the first Software Defined Networking solutions. At Schuberg Philis we […]
The IPoIB driver supports two modes of operation: Unreliable Datagram (UD) and Connected Mode.
In Unreliable datagram mode, the IB UD (Unreliable Datagram) transport is used and so the interface MTU has is equal to the IB L2 MTU minus the IPoIB encapsulation header (4 bytes). In QDR, the default NTU value is 2044. In FDR onwards, the default MTU value for Unreliable Datagram is 4096.
Born in the logic of ones and zeroes and forged in the heat of battle, two hypervisors–sworn foes in the realm of virtualization–are about to unite in a way many never thought possible. Over beer and code.
It’s still a hot topic in my customer conversations: Should we use Oracle Data Guard or something else for providing disaster recovery?
I’ve written an explanation a while ago. Recently I also created a powerpoint slide comparing various features – in an attempt to be as unbiased as possible (I think I partly succeeded ;)
There is one big problem in research for better logging methods: no good logging sample repositories exist. Well, not even bad ones... I am currently doing some preliminary steps towards a new, better log normalization system. Among others, it will contain a structure analyzer which will remove much of the manual burden of creating normalization rules. But, guess what: while the project looks very promising, lack of log samples is a real big problem!
You can use the ibdiagnet to generate the topology of the IB Network simply by using the “-w” switch
