The maximum number of disk enclosures cascaded using a 6 Gbit/s SAS expansion port on controller enclosures of OceanStor T Series S2200T/S2600T V100R005 storage systems (the number of disk enclosures cascaded in each loop): S2600T: 11 S2600T (single controller): 4 S2200T (single controller): 4 S2200T (dual controllers): 8

The maximum number of disk enclosures cascaded using a 6 Gbit/s SAS expansion port on controller enclosures of OceanStor T Series S5500T V100R005 storage systems (the number of disk enclosures cascaded in each loop): If a controller enclosure has 12 disk slots, an expansion port can cascade a maximum of 12 disk enclosures. If a controller enclosure has 24 disk slots, EXP0 and EXP1 can cascade a maximum of 11 and 12 disk enclosures respectively.

Method used to power on OceanStor T Series V100R005 storage systems: SAN storage system power-on procedure is as follows: switch on all the external power supplies > press the power button on any controller > power on Ethernet or Fibre Channel switches (applicable if the Ethernet or Fibre Channel switches are deployed but not powered on) > power on application servers (applicable if the application servers are not powered on). NAS storage system power-on procedure is as follows: switch on external power supplies > power on Ethernet switches > power on Fibre Channel switches > power on storage unit controller enclosures (SUCs) and storage unit disk enclosures (SUDs) by pressing either power button of the SUC > power on file engines by pressing the power button of file engine nodes in the cluster at an interval of one minute.
