VNX DPE / DAE SAS cabling

A quick note to clarify SAS cabling between EMC VNX and extra enclosures or DAE’s as they are called.

When setting up a VNX with only the base DPE enclosure, there’s no need for cabling.

When adding the first and the second enclosure, you need a special kind of SAS cable, called the “mini-SAS to mini-SAS HD cables”.

When adding a third enclosure or more, you need a “mini-SAS to mini-SAS cable”.

VNXSAS3

 

The following is an overview on the partnumbers for both situations:VNXSAS

you know the problem, the application window maximizes, but outside the Windows 8 viewing area and no way to retrieve it, resize, move….. #DOH !

the trick:

  • use ALT-TAB to select the application
  • then use the combination WINDOWS + LEFT ARROW keys to move the screen back in sight !

#Netgear #WNDR4500 down, power led blinking green

Last week, I woke up and noticed my wifi was not working.
After investigation, my wifi-router, NETGEAR WNDR4500 N900, seem to be in some kind of trouble.
The powerled was blinking green and I could not access it anymore.

The blinking green led means that the routers suffers from corrupted firmware, don’t know why this happened.

More info can be found at http://kb.netgear.com/app/answers/detail/a_id/18989/kw/wndr4500%20corrupted%20firmware%20recovery%20tool%20lost%20cd

Anyway the solution in short is to download a firmware package, then upload this to the router via TFTP and after a reboot, the green blinking led will stabilize and all functionality will return.
In my case the config was intact, so no harm was done.

In the meantime I also a logged a support call with NETGEAR Support, the morning after, they already responded with via email that “The router is suffering from a corrupted firmware. This cannot be restored so the router has to be exchanged.

Thanks you Netgear Support, but I consider myself technical enough to go for the self-repair option.
