IfMore specifically, the Planning for hardware section of that link, for instance:
https://www.ibm.com/docs/en/flashsystem-7x00/8.7.0?topic=hardware-control-enclosure-environmental-requirements
The FlashSystem 7300 is a 2 Rack unit 24 drive active active architecture that includes the ability to expand to additional capacity via SAS attach expansions. If you have only purchased the Controller with drives, you only need the 2Rack U. If you are planning for additional capacity growth over time, evaluate what your expansion unit is and the total planned max. Having said the above, with IBM Flash Grid you may want to consider scaling out rather than scaling up.
TLDR: 2 Rack U, Nezih has given you the primary link for all basic information, the link I have provided is the more specific link about the control enclosure you have purchased.
I hope that helps!

Hi Nezih. Thanks for quick response. So, as per our configuration this is what we will be needing. So looks like there will be one 2U Enclosure there with front side all the 18 drives, and rear-side the controllers/Ports etc for FC Hosts connectivity etc. Is that understanding correct. Please share some more details. Thanks.

Hello All. We've a new FS7300 upcoming. We want to identify how much rack space is needed in the DC. 2U or 5U and how many etc. Like space for Expansion Enclosure etc. We're referring to 'Physical Installation and Planning' Guide, but not able to find the exact info as it keeps mentioning ' must meet certain requirements' in each sentence. Also, like control enclosures have specific requirements. But what are those. As, we want to register that requirement with the Data Center people.
Our config is: 18 Drives , 19.2 TB each = 257.83 TiB Usable. So, basically one Controller Enclosure. And, is the 18 Drives enclosure is in the same Controller Enclosure Front side or it is a different enclosure. And, are these two 2U or 5U SAS Expansion Enclosures. How to identify that. Thanks.
