Technical Specifications
The following tables provide technical specifications for the SC5020 series storage systems.
| Drives | |
|---|---|
| SC5020: SAS hard drives |
Up to 30 2.5-in. SAS hot-swappable HDDs (12 Gb SAS) |
| SC5020F: SAS SSDs |
Up to 30 2.5-in. SAS hot-swappable SSDs (12 Gb SAS) |
| Storage Controllers | |
|---|---|
| Storage controllers |
Two hot-swappable storage controllers with one I/O card slot and one optional mezzanine card per storage controller. Each storage controller has an internal battery backup unit. Write cache is mirrored between the two storage controllers. If a power failure occurs, the battery backup unit provides power to the storage controller so that the write cache can be saved to an SSD within the storage controller. |
| Storage Connectivity | |
|---|---|
| Configurations |
SC5020: Supports a total of 222 drives and up to 192 drives on a single SAS chain. The SAS chain supports up to sixteen SC400 expansion enclosures, eight SC420 expansion enclosures, or three SC460 expansion enclosures. SC5020F: Supports a total of 222 SSDs and up to 192 SSDs on a single SAS chain. The SAS chain supports up to eight SC420F expansion enclosures . |
