This video covers storage or Sass cabling for new Power Protect Data domain 6900 systems. A standard Power protect DD 6900 system will have 1 to 8 ES 40 storage shelves and an ES 40 will have 15 4 terabyte disk drives. This video does not cover how the hardware is mounted in the rack.
Please refer to the installation guides for the various components for information on how to rack if you were to purchase a pre system. This is what it would look like. You can see the power protect DD 6900 and the eight ES 40 S. These are positioned in the rack to make cabling as simple as possible.
There are two reasons for the gap between the DD 6900 and the fifth ES 41 U. Of the gap is to allow for the cable management arms that are mounted to the rear of the power protect DD 6900. The remainder allows for the addition of a second power protect DD 6900 that will be used in an A A system. You can drop the ES 40 by three U. If you plan to never convert your system to H A.
This in turn leaves more space in the rack for equipment if desired. Here's the back view of an ES 40. There are two controllers with B on top and A on bottom. The port identifiers that the SAS cable can plug into are on the bottom. This is the back view of a power protect DD 6900 showing the location of the SAS controllers and their port identifiers.
The blue and green lines represent SAS cables. The blue lines go to the power protect DV. 6900 controller. On the right hand side, the cable goes from the PC IE Sass card port A two port A of controller A on the top ES 40. On the left hand side, the cable goes from the PC IE SA S card port A two port A of controller B on the bottom ES 40.
The four ES 40 S here are said to be in the same chain. The green line represents the cables that complete the chain. On the right hand side, it connects port B of controller B on the top ES 42 port A of controller B. On the next one down on the left hand side, it connects port B on controller A on the bottom ES 42 port A of controller A on the next one up, this continues on to complete the chain.
In this view, we see how the next four ES 40 s are connected. In this case, the purple lines represent the cables going from the SA S card port B on the right to the top ES 40 from the SA S card port B on the left to the bottom ES 40 of that group, the green lines are connected to the same as the first chain on the bottom that covers a non H A power protect DD 6900 system.
The ES four are installed from the bottom. Consider the use of an anti ti mechanism or have the rack bolted to the floor. This shows a full H A configuration. You'll notice that the two chains of the ES 40 are in the same position. The cabling here is the same as a non A system with the addition of an FS 25 as well as the network cables that interconnect to the second power protect DD 6900.
For the bottom ES 40 the yellow connections have been added on the left. They go from the second power protect DD 6900 SAS port A to the top ES 40 port B of controller A and on the right from the SA Sport A to the bottom ES 40 port B of controller A for the top chain, red connections have been added on the left.
They go from SA Sport B to the top ES 40 port B of controller B and on the right from port B two port B of controller A on the bottom es 40 of the chain, the third chain for both power protect DD 69 hundreds connect to the FS 25 from the first power protect DD 6900.
The orange connections on the left go from SA Sport C to the FS 25 port A on controller A and on the right from SA Sport C to the FS 25 port A of controller B, the light blue connections from the top power protect DD 6900 go from the left SAS port C to the FS 25 port B of controller A and on the right from SAS port C to the FS 25 port B of controller B, there's a fair amount of flexibility when installing a power protect DD 6900 in a rack.
These recommendations are based on creating a consistent layout so we can provide the correct cabling with an order and create a system that is accessible and serviceable as such. 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 new systems 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.
