Storage Center 7.5.10 Release Notes

Environmental and system requirements

This section describes environmental and system requirements in this release.

Storage Manager 2020 R1 or later is required to manage storage systems running Storage Center 7.5.10 and Storage Center 7.5.10 supports the following storage system models:

  • SC9000
  • SC8000
  • SC7020F
  • SC7020
  • SC5020F
  • SC5020
  • SC4020
  • SCv3000 Series
  • SCv2000 Series
NOTE Storage Center 7.5.10 supports cabling mixed-speed expansion enclosures. SC400, SC420, and SC420F expansion enclosures can be cabled with SC200 and SC220 expansion enclosures.

Storage System Scalability Guidelines

The following table lists the scalability guidelines for dual-controller storage systems:
Table 1. Scalability Guidelines for Dual-Controller Storage SystemsScalability guidelines
Storage System (memory per controller) Raw (512 KB pages) Addressable (512 KB pages) Raw (2 MB pages) Addressable (2 MB pages) Raw (4 MB pages) Addressable (4 MB pages)
SC9000 (128 GB or 256 GB) 1500 TB 1000 TB 6000 TB 4000 TB 12,000 TB 8000 TB
SC8000 (64 GB) 750 TB 500 TB 3000 TB 2000 TB 3000 TB 2000 TB
SC7020F or SC7020 (128 GB) 1000 TB 650 TB 4000 TB 2600 TB 8000 TB 5200 TB
SC5020F or SC5020 (64 GB) 540 TB 350 TB 2160 TB 1400 TB 4320 TB 2800 TB
SC4020 (16 GB) 263 TB 175 TB 1054 TB 700 TB 1054 TB 700 TB
SCv3000 Series (16 GB) 250 TB 169 TB 1000 TB 675 TB 2000 TB 1350 TB
SCv2000 Series (8 GB) 168 TB 112 TB 672 TB 450 TB N/A N/A
NOTE In the release notes for Storage Center 7.2 and Storage Center 7.1, the supported maximum storage space for an SC4020 using a 512 KB page size was incorrectly calculated as 500 TB raw and 400 TB addressable. The correct supported maximum storage space for an SC4020 using a 512 KB page size is 263 TB raw and 175 TB addressable.
