The lack of programmability in existing networking hardware is a problem—especially to private cloud and virtual data center customers. Such users need better programmability in the network in order to deliver applications and services. Software Defined Networks (SDNs) answer this need, and most companies such as Cisco, HP and Juniper are delivering on an SDN strategy, as is VMware.

xStream family 4.1 will include a feature enhancement, which is important for internal compliance and audit: Message of the day banner (MOTD). This banner can include organization-specific warnings and messages that appear to any one that is accessing the system after the login credentials were provided successively.

Since this question is being asked more frequently, I decided to...

In the following few days we will be releasing the next version of Director xStream product family (Director xStream, iLinkAgg xStream and xBalancer). One of the more important capabilities in this release, which is currently in beta, is High Availability and device redundancy, which is available for selected xBalancer customers for more than a year and now will be available for all 3 products customers as part of the software update.

The High Availability and redundancy feature (I’ll name it HA from this point on) applies to all three xFamily models – Director xStream, iLinkAgg xStream...
