This video covers storage or SAS cabling for New Power Protect Data domain. 9900 systems. A standard Power Protect DD 9900 system will have 2 to 5 DS 60 storage shelves and an FS 25 shelf. The DS six have some number of eight terabyte disk drives organized in groups of 15, the FS 25 which there is only one of has either 10 or 16 3.84 terabyte S SDS used to accelerate various functions within the data domain operating system.
This video does not cover how the hardware is mounted to the rack if needed. Please refer to the installation guides for the various components. For further information, if you have purchased a pre racked system, this is what it should look like. You can see the power protect DD 9905 DS six S and the FS 25.
These are positioned in the rack to make cabling as simple as possible. Each DS 60 has cable management assemblies or C MA S located beneath it. There are two reasons for the gap between the power protect DD 9900 and the third DS 61 view of that gap is to allow for the cable management arms that are mounted to the rear of the DD 9900.
The remainder is to allow for the addition of a second power protect DD 9900 that would be used in an H A system. You can drop the DS 60 S and their C MA S by for you. If you plan to never convert your system to H A, the reason for the gap between the top Ds 60 the Fs 25 is to simplify, support.
The DS 60 is almost 1 m deep while the Fs 25 is much shallower. If the Fs 25 were mounted right on top of the DS 60 it would be very difficult to reach the back to add or remove cables or to swap power supplies or controllers. Here is the back of the DS 60. There are two controllers with B on the left and A on the right.
The port identifiers that SAS cables can plug into are on the bottom. The red and green lines represent SAS cables. The red lines go to the powertech DD 9900 controller. On the right hand side, the cable goes from port A on the PC IE SAS card to port zero on controller A on the bottom DS 60.
On the left hand side, the cable goes from port A on the PC IE SA S card to port zero of controller B on the second from bottom DS 60 these two Ds six are said to be in a chain. The green lines represent the cables that complete the chain. On the right side, it connects port zero on the second DS 62 port two.
On the first, on the left side, it connects port two on the second DS 62 port zero. On the first. In case you are wondering why there is a blank space on the bottom of the rack. When installed in some racks, there would be no room to get PDU power cables down through the middle of the rack. Without that space, you can judge whether it's necessary for your system. For the next chain.
The yellow lines represent the cables going from a scar port C on the right to the third DS 60 from the SA scar port C on the left to the fourth DS 60. The green lines are connected the same way as the first chain. The third chain is shown with pink lines which go to only one Ds 60.
This is a good example. In case you have just three Ds six, the cables go from port zero on H DS 60 controller to port B on the SAS cards. The final chain goes to the Fs 25. In this case, the orange lines represent the cables on the A S cards. They go from the respective Port D's and are connected to port A of the two controllers.
The Fs 25 is given its own chain for performance reasons. The DS six S are installed from the bottom because they're heavy. The Dell E MC racks that are used in pre rack systems are designed with an interlock that prevents more than one Ds 60 from being pulled out of the rack at a time. Any other racks must use an anti TI mechanism or be bolted to the floor.
Let's take a look at a full H A configuration. You'll note that the three Ds six are in the same position. The cabling here is the same as a non H A system. With the addition of the network cables that interconnect to the power protect DD 9900 for the bottom two DS six, the purple connection has been added on the left.
They go from a sport A to port two of controller B on the first DS 60 on the right from SA S port A to port two of controller a of the second DS 60 for the next chain, the blue connections have been added on the left. The connections go from SA S port C to port two of controller B on the third DS 60 on the right from SA Sport C to port two of controller A of the fourth DS 60.
The third chain for the fifth DS 60 has green connections on the left. The connection goes from Sport B to port two on controller B of the fifth DS 60 on the right from Sass port B to port two of controller A on the 50th 60. Finally, the fourth chain goes to the FS 25 which adds the connections on the left from SA S port D to port B of controller B.
And on the right from SA Sport D to port B of controller A, there's a fair amount of flexibility when installing a power protect DD nine and 900 in a rack. These recommendations are based on creating a consistent layout, meaning we can provide the correct cables with an order and create a system that is accessible and serviceable.
This is not the only way to create a system. Customers may have other requirements. We have rules and guidelines that can be applied to each system as well as upgrades. These are covered in greater depth in the documentation for more information about set up and configuration processes for power protect DD visit support dot E MC dot com.
