These extended RAID options are ONLY available on the "double wide" Limulus desk-side case (Models 1202, 1302, 1222)
To ensure safe data storage, all bulk storage on Limulus system uses RAID arrays. This storage is optional and not needed for basic Limulus operation. To be properly configured this upgrade must be purchased with a Limulus system.
Drives are high quality and data center rated ( "spinning disk" ) with a 5 year warranty.
These options in include all the standard RAID sized plus additional sized up to 180TB. All RAID is configured and managed using Linux "md" (multidisk) software RAID.
The amount of storage is implemented as follows
| Usable-Storage-Size | Drives | Drive-Size | RAID-Level |
| 14 TB | 2 | 14 TB | 1 |
| 24 TB | 6 | 6 TB | 6 |
| 40 TB | 6 | 10 TB | 6 |
| 56 TB | 6 | 14 TB | 6 |
| 72 TB | 6 | 18 TB | 6 |
| 100 TB | 12 | 10 TB | 6 |
| 140 TB | 12 | 14 TB | 6 |
| 180 TB | 12 | 18 TB | 6 |
NOTES:
- All drives are enterprise quality (not consumer grade shingled storage).
- All Limulus systems come with professional grade SSD drives for basic OS and user storage. Hadoop/Spark systems use SSD drives for HDFS. The RAID sets above are for optional bulk centralized storage. Check the specification for your model.
- These RAID sets are available on all Limulus models and MUST be included as part of the original specification. These are not user installable upgrades.
