An enclosure is a container for drives that store data written to the S11 or S31 Node and drives that store the S11 or S31 Node internal database. An HCP S11 Node includes one base enclosure and, optionally, one expansion enclosure. An HCP S31 Node includes one base enclosure and, optionally, up to eight expansion enclosures. The base enclosure for both S11 and S31 Nodes contains the two server modules that run the HCP S Series software.
Each enclosure has a main bay and a controller bay. The main bay holds most of the drives. The controller bay holds the server modules (base enclosure) or I/O modules (expansion enclosures) and some additional drives.
Enclosure hardware
Each enclosure includes the hardware listed below.
- Rail kit
- The rail kit, with left and right rails, is used to mount the enclosure in a rack. The rail kit includes inner mounting rails that attach to the enclosure and outer mounting rails that attach to the rack.
- Cable management arm
- The cable management arm is used to neatly arrange the power cables that connect the enclosure to the power distribution units (PDUs), the SAS cables that connect expansion enclosures to other enclosures, and, for base enclosures only, the network cables that connect the server modules to your networking infrastructure. The cable management arm also keeps the cables securely connected to the enclosure when the enclosure is pulled partway out of the rack for service.
- The cable management arm comes with two brackets, one that attaches to the enclosure and one that attaches to the right outer mounting rail.
- The cable management arms differ for base and expansion enclosures.
- Stabilizer bar
- The stabilizer bar, which is attached to the left and right outer mounting rails at the rear of the rack, provides support for the rails.
- Two power supplies
- The two redundant power supplies at the rear of the enclosure provide power for the enclosure. Each 3200W power supply in a base enclosure has two inlets to provide the extra level of power required by the server modules. Each 2000W power supply in an expansion enclosure has one inlet.
- The power supplies are not interchangeable between base and expansion enclosures.
- The newest power supplies are ecodesign-compliant power supplies that comply with the European Union (EU) ecodesign regulations regarding active efficiency and no-load power consumption. These power supplies are required in S11 and S31 Nodes located in EU member countries.
- Four rear fans
- The four fans at the rear of the enclosure provide cooling for the drives and SAS expanders in the main bay.
- Two controller-bay fans
- In base enclosures, the fans in the controller bay provide cooling for the server modules, personality modules, and drives in the controller bay. In expansion enclosures, the fans in the controller bay provide cooling for the I/O modules and drives in the controller bay.
- The controller-bay fans are not interchangeable between base and expansion enclosures.
- Data drives
- These 10TB, 14TB, 16TB, 18TB, or 20TB SAS hard disk drives (HDDs), with drive carriers, store object data and object and system metadata. A base enclosure holds 30, 62, or 94 data drives, all in the main bay. An expansion enclosure holds 42, 74, or 106 data drives, 10 in the controller bay and the rest in the main bay.
- Six database drives (base enclosures only)
- These 400GB or 800GB SAS solid state drives (SSDs), with drive carriers, store the internal database used by the S11 or S31 Node to hold information such as user-account and bucket definitions and various configuration settings. Database drives also store information that helps ensure high availability and data reliability.
- Four of the database drives are in small form factor (SFF) drive carriers in the controller bay. The other two are in large form factor (LFF) drive carriers in the main bay.
- Two personality modules (base enclosures only)
- Each of the two personality modules, located in the controller bay, provides connectivity between one of the server modules and the drives in the base enclosure. Each personality module contains a SAS controller and two SAS expanders.
- Two I/O modules (expansion enclosures only)
- The two I/O modules, located in the controller bay, enable communication with the drives in that enclosure. Each I/O module contains two SAS expanders and has four 4-lane 12Gb SAS ports.
- Each I/O module also has one serial port, which can be used for diagnostic functions, and two Ethernet ports, which are not used with an S11 or S31 Node.
- Eight SAS expanders
- The eight SAS expanders in the main bay connect the personality modules (base enclosures) or I/O modules (expansion enclosures) to the drives in the main bay.
- The SAS expanders are configured in four pairs. One SAS expander in each pair connects one of the personality or I/O modules to 24 drives. The other SAS expander in each pair connects the other personality or I/O module to the same 24 drives.
- Four 12Gb SAS ports (base enclosures only)
- The four 4-lane SAS ports on the back of the enclosure are used to connect the base enclosure to the I/O modules in an expansion enclosure.
- Four IEC 320 C13 to IEC 320 C14 power cables with up-angle connectors (base enclosures only)
- These power cables are used to connect the power supplies in a base enclosure to two different PDUs. For all regions except India, two of the cables are 6 feet (1.83 meters) long, and two are 8 feet (2.44 meters) long. For India, all four cables are 2.4 meters long.
- Four IEC 320 C13 to IEC 320 C14 power cable extensions (base enclosures only)
- These power cable extensions, which are 2.3 feet (0.7 meters) long in all regions, are used only if the base-enclosure power cables aren't long enough to reach the applicable PDU outlets.
- Two IEC 320 C19 to IEC 320 C20 power cables with left-angle connectors (expansion enclosures only)
- These power cables are used to connect the power supplies in an expansion enclosure to two different PDUs. For all regions except India, one of the cables is 6 feet (1.83 meters) long, and the other is 8 feet (2.44 meters) long. For India, both cables are 2.4 meters long.
- Two IEC 320 C19 to IEC 320 C20 power cable extensions (expansion enclosures only)
- These power cable extensions, which are 3 feet (0.91 meters) long in all regions, are used only if the expansion-enclosure power cables aren't long enough to reach the applicable PDU outlets.
- Two 4-meter SAS cables (expansion enclosures only)
- The two SAS cables are used to connect the expansion enclosure either to the base enclosure or to two other expansion enclosures.
Server module hardware
Each of the two server modules in an S11 or S31 Node includes the hardware listed below.
- One (S11 Nodes) or two (S31 Nodes) CPUs
- These CPUs provide the processing power for the server module.
- Two (S11 Nodes) or eight (S31 Nodes) 32GB memory cards
- These memory cards provide an S11 Node with a total of 64 GB of RAM. They provide an S31 Node with a total of 256 GB of RAM.
- Two 256GB M.2 SSDs
- The two SSDs store the HCP S Series operating system (OS). They also store logs and software used by the S11 or S31 Node.
