Session Initiated Protocol (SIP): A Five-Function Control Protocol by F5 Networks
44; a standard method of providing sessions is needed.

Many protocols came before SIP, such as H.323. While H.323 provided an all-in-one solution, it was not flexible enough to provide for much beyond voice services. SIP also brings Web 2.0 concepts into fruition, but in a completely different manner.

SIP is a primitive in that it does not provide services; it provides a conduit for services. For example, consider SIP a regular telephone line. The telephone line doesn't provide a...
Achieving Common Internet File System (CIFS) Acceleration by F5 Networks
for various higher level Microsoft communications protocols, as well as for network printing, resource location services, remote management/administration, network authentication (secure establishment services) and RPC (Remote Procedure Calls).

Arrays Score with Both File and Block by Storage Magazine
There are pros and cons to running multiple protocols through a single array controller. File-system protocols like CIFS and NFS treat files as a single entity. For example, when a user opens a file, it's opened in its entirety and then locked to prevent others from modifying it. This is ill-suited for apps where data is accessed at a sub-file level, such as databases where small pieces of information are continuously read and updated within a larger file. Without question, block...
Get Your iSCSI Game On: Best Practices by Storage Magazine
You don't have to be an iSCSI cheerleader, but you should know the score when it comes to this maturing protocol. iSCSI, the flagship IP SAN protocol, now enjoys or should enjoy the same respect as Fibre Channel (FC). But with respect comes responsibility. While some storage administrators may be hesitant to have iSCSI in their environments, it should be treated as a mature protocol and deserves the same level of administrative discipline deployed for FC networks. There are plenty of...
