There is a new Single Sign On service that increases security and control by allowing the software components to communicate with each other through a secure token mechanism. Depending on the size and complexity of your installation, there may also be a changed setting for the vCenter Server Administrator(s) of your organization.

Using Tunneling to Transition to IPv6

Cisco, Cloudera, Featured, Professional Development, Project Management, Routing & Switching, Technology, Training in Business

One of the many useful features of tunneling is to carry non-IP traffic across an IP network, and this is still the case when dealing with IPv6 traffic. This transition mechanism makes use of a configured tunnel to transport IPv6 over a native IPv4 network, which may consist of two sites or more. Unlike the previous transition mechanisms, tunneling is not monolithic; while the basic principles may be similar, the operations are different. The following chart gives a breakdown of the current, major tunneling types in use, particularly in a Cisco environment:

Maintaining the High Availability of Server-based Data

Cisco, Cloudera, Featured, Professional Development, Project Management, Routing & Switching, Technology, Training in Business

Obviously, maintaining the availability of Server-based data is one of the primary objectives of any Server Administrator. With the “Data Verification and Auto Correction” process provided by ReFS we’re able to support that availability goal. While the self-healing aspects of such a file system existed in the Server 2008 versions of the operating system, ReFS takes that support capability to a level of higher resiliency. As described above, ReFS can auto-detect data corruption and then “self-heal.” This means that the file system can perform any corrections and repairs necessary without needing to take the file system offline.
