Last month, Oracle released Oracle VM Server for SPARC release 3.2 which includes numerous enhancements. One of these is improvement for virtual disk multipathing, which provides redundant paths to virtual disk so that disk access continues even if a path or service domain fails.
When Docker first rocketed into the nerdosphere in 2013, some wondered how we at Joyent felt about its popularity. Having run OS containers in multi-tenant production for nearly a decade (and being one of the most vocal proponents of OS-based virtualization), did we somehow resent the relatively younger Docker?
A friend mentioned that small/middle companies are using mainframes, but I think an argument could be made that Google and Facebook and friends are really creating the new mainframe with there various server nodes that are often made up of custom tasked designed hardware/servers.
As part of a work-related project, I'm writing code that needs to resolve DNS names using Go, on illumos.
While doing this work, I noticed a very surprising thing. When a host has both IPv6 and IPv4 addresses associated with a name (such as localhost), Go prefers to resolve to the IPv4 version of the name, unless one has asked specifically for v6 names.
