Simplivity OVC memory size

[jskim88]

How is the OVC memory size configured based on the storage size in Simplivity 380 Gen10 G node and Gen10 Plus models?

Hello @jskim88,
Thank you for using HPE SimpliVity forums. 

The amount of memory on the OmniStack controllers is preconfigured based on the model and size of the node. The larger the system it will have more minimum memory requirements.

I understand that the larger the storage size, the more OVC memory.

For example, I want to know the OVC memory size when there are 6 x 1.92TB SSDs and the OVC memory size when there are 12 x 1.92TB SSDs.

I want to know the amount of OVC memory that SimpliVity allocates based on all disk specifications.

6 x 1.92 TB SSD kit --> OVC Memory Size ?
8 x 1.92 TB SSD kit --> OVC Memory Size ?
9 x 1.92 TB SSD kit --> OVC Memory Size ?
12 x 1.92 TB SSD kit --> OVC Memory Size ?
16 x 1.92 TB SSD kit --> OVC Memory Size ?
18 x 1.92 TB SSD kit --> OVC Memory Size ?
24 x 1.92 TB SSD kit --> OVC Memory Size ?
8 x 3.84 TB SSD kit --> OVC Memory Size ?
9 x 3.84 TB SSD kit --> OVC Memory Size ?
12 x 3.84 TB SSD kit --> OVC Memory Size ?

It is important to inform the customer in advance.

At the moment I don't have any document with that information to share with you. You may need to go through your account team.

From my own calculation based on the online sizer, it’s these OVC mem reservations ( but please double check ).

6 x 1.92 TB SSD kit --> OVC Memory Size --> 48 GB
8 x 1.92 TB SSD kit --> OVC Memory Size --> 72 GB
9 x 1.92 TB SSD kit --> OVC Memory Size --> 68 GB ( FTT2 )
12 x 1.92 TB SSD kit --> OVC Memory Size --> 92 GB
16 x 1.92 TB SSD kit --> OVC Memory Size --> 116 GB
18 x 1.92 TB SSD kit --> OVC Memory Size --> 107 GB ( FTT2 )
24 x 1.92 TB SSD kit --> OVC Memory Size --> 193 GB
8 x 3.84 TB SSD kit --> OVC Memory Size --> 122 GB

9 x 3.84 TB SSD kit --> OVC Memory Size --> 115 GB ( FTT2 )
12 x 3.84 TB SSD kit --> OVC Memory Size --> 197 GB
