I did have some calls at that point from customers who couldn&#8217;t understand why the &#8220;passive&#8221; controller had all the connections. It did take some explaining to tell them, there was nothing wrong, and this was all part off the Equallogic virtualization.<\/p>\n<p>From type 3 I believe it was, until the type 10 controllers, we only had the controller failover, where the whole controller was failed over to the secondary.<\/p>\n<p>BUT now it&#8217;s back to basics, Dell has re-introduced the &#8220;Vertical Port Failover&#8221; on type 11 and 12 controllers. This is a significant gain, as you can fail a single network cable, and still be sure you have maximum throughput. As an old Equallogic guy this sweetens my heart.<\/p>\n<p>By the way, Dell has also introduced some new arrays with the type 11 and 12 controllers. The type 11 is actually for the new PS6100 series 1Gbit arrays, and besides 4 x 1Gbit ports this also feature a separate management port. The PS6100 comes in different flavours, the 4U 24&#215;3.5&#8243; disk SATA based, and the 2U 12&#215;3.5&#8243; or 24&#215;2.5&#8243; disks in SAS or nearline SAS drives.<\/p>\n<p>The type 12 controllers is the PS4100 with same configuration options as the bigbrother, but still the 4000 departemental arrays still has 2x1Gbit networking ports, and a management port.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A good colleague of mine pointed out a very interesting feature in the new PS6100 arrays, recently announced by Dell, the vertical port failover.
