An S11 or S31 Node comes with one base enclosure and, optionally, one expansion enclosure (S11 Nodes) or one through eight expansion enclosures (S31 Nodes). Each enclosure contains an initial set of drives and, optionally, one or two capacity upgrade drive sets:
- The initial drive set for a base enclosure consists of 30 data drives and six database drives.
- The initial drive set for an expansion enclosure consists of 42 data drives.
- A capacity upgrade drive set consists of 32 data drives.
Data drives are 10TB, 14TB, 16TB, 18TB, or 20TB HDDs. Database drives are 400GB or 800GB SSDs.
The tables below show information about the initial drive sets and capacity upgrade drive set for 10TB, 14TB, 16TB, 18TB, and 20TB drives. Each table shows the information listed below.
- Total raw capacity
- The total of the manufacturer-specified capacities of the data drives.
- Total storage
- The total amount of storage that the S11 or S31 Node can use for storing, protecting, and repairing object data and object and system metadata. For the base-enclosure initial drive set, total storage includes the space that can be used for data and metadata on the database drives.
- Total storage is not the same as the amount of data that can be written to an S11 or S31 Node. The space required for metadata, protection, and repair reduces the amount of storage available for the data written to the S11 or S31 Node. However, single-instancing of data enables the amount of data written to exceed the total amount of storage.
- Licensable storage
- The maximum amount of storage that can be licensed on the S11 or S31 Node. This value is the amount of storage available for storing and repairing object data and object and system metadata. Licensable storage does not include the additional storage required for protecting data and metadata. For the base-enclosure initial drive set, licensable storage includes the space that can be used for data and metadata on the database drives.

Approximate total storage on an S11 or S31 Node
To estimate the total storage on an S11 or S31 Node, add together the storage provided by the applicable drive sets. Here are some examples of total storage, where the totals are calculated using exact numbers of bytes and then rounded to terabytes instead of being calculated using the rounded values shown in the tables above:
- The total storage on a two-enclosure S11 Node that uses 10TB data drives and 400GB database drives and has two capacity upgrade drive sets in each enclosure is approximately 1,813.18 TB.
- The total storage on a five-enclosure S31 Node that uses 14TB data drives and 800GB database drives and has two capacity upgrade drive sets in each of the first four enclosures and one capacity upgrade drive set in the fifth enclosure is approximately 6,167.07 TB.
- The total storage on a nine-enclosure S31 Node that uses 16TB data drives and 800GB database drives and has two capacity upgrade drive sets in each enclosure is approximately 13,657.12 TB.
- The total storage on a nine-enclosure S31 Node that uses 18TB data drives and 800GB database drives and has two capacity upgrade drive sets in each enclosure is approximately 15,363.12 TB.
- The total storage on a nine-enclosure S31 Node that uses 20TB data drives and 800GB database drives and has two capacity upgrade drive sets in each enclosure is approximately 17,070.09 TB.
