Planning the model 993 rack configuration
Ensure that the rack where you plan to install your storage system meets the rack requirements.
About this task
When you are planning the rack for your DS8910F Rack Mounted storage system (model 993), you must
answer the following questions that relate to rack specifications and available space:
• Where are you installing the storage system? The model 993 is a rack mountable system. There are
three different rack scenarios:
– An existing IBM Z model ZR1
– An existing IBM LinuxONE Rockhopper II model LR1
– Other standard 19-inch wide rack that conforms to EIA 310D specifications:
- 19-inch EIA rails
- Minimum rail depth of 700 mm
- Maximum rail depth of 780 mm
• Does the rack in which you are installing the model 993 have adequate space to accommodate the
components? The rack must have a minimum of 15U contiguous space to mount the modules.
– The standard 19-inch wide rack installation (feature code 0939) supports an optional second High
Performance Flash Enclosure Gen2 pair (feature code 1605). If you plan to order the second High
Performance Flash Enclosure Gen2 pair, you must have an additional 4U contiguous space in your
standard 19-inch wide rack. The optional second High Performance Flash Enclosure Gen2 pair is not
available with the model ZR1 installation (feature code 0937) or the model LR1 installation (feature
code 0938).
– The standard 19-inch wide rack installation (feature code 0939) supports an optional 1U keyboard
and display (feature code 1765). If you plan to order the 1U keyboard and display, you must have an
additional 1U contiguous space in your standard 19-inch wide rack. For accessibility, the keyboard
and display must be mounted at a height of 15 - 46 inches. If you add the keyboard and display,
ensure that you provide adequate space to accommodate them. The optional 1U keyboard and
display are not available with the model ZR1 installation (feature code 0937) or the model LR1
installation (feature code 0938).
