Flex Slot BBU packs power into your rack


In this Coffee Coaching session, Darrel Gaston looks at a few of the HP and Microsoft technologies created to keep customers' IT highly available.





First, Darrel looks at a feature from Microsoft. In Windows Server 2012 R2, Microsoft implements a Failover Clustering feature, which provides high availability and scalability for many server workloads. For this feature, the clustered servers (called nodes) are connected by physical cables and by software. If one or more of the cluster nodes fail, other nodes begin to provide service (a process known as failover).


Microsoft is not the only one with technologies to help customers; HP is doing a lot too!


Did you know that HP is the largest provider of X86 servers? Because of this, they are constantly looking for new technologies to enhance their customers’ experiences with their products. A new example of this is the Flex Slot Battery Backup Unit (BBU) introduced for the Gen9 DL360 and DL380 server platforms in March 2015.


Starting with Gen9, the power team utilized new technologies, which allowed HP to make the power supply smaller than ever. This new form factor is called Flex Slot. Flex Slot power supplies convert the incoming power to be compatible with the server. Likewise, the Flex Slot BBU monitors the server power and provides up to 750W for 60 seconds in the event of a power outage.


To save batter capacity in the event of back-to-back outages, the Flex Slot BBU will terminate the discharge mode of the BBU after incoming power has stabilized (in the case that the power goes out but then returns after a brief time).


On the back of the Flex Slot BBU, there is an LED to indicate its status:

  • Green means the BBU is fully charged and ready to support the server in the event of an outage
  • Amber means the BBU is in charge cycle
  • Blinking green means the BBU is in discharge mode
