An enclosure is a container for drives that store data written to the S32 Node or drives that store the S32 Node internal database. An S32 Node includes one base enclosure, one expansion enclosure, and, optionally, up to eight more expansion enclosures.
The base enclosure contains the two server modules that run the HCP S Series software. The expansion enclosures for S32 Nodes are interchangeable with the S11 and S31 Node expansion enclosures, but the base enclosure is for S32 Nodes only.
Base enclosure hardware
Each base enclosure includes the hardware listed below.
- Rail kit
- The rail kit, with left and right rails, is used to mount the base enclosure in a rack. The base enclosure rail kit consists of mounting rails that attach to the rack.
- Two power and cooling modules
- The two redundant power and cooling modules at the rear of the enclosure. Each module has a 764W power supply that provides power to the enclosure and a fan that provides cooling for the base enclosure components. The power supply has one power inlet.
- Six database drives
- The six 800GB SAS solid state drives (SSDs), with drive carriers, store the internal database used by the S32 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. In the remaining space, database drives can store object data and object and system metadata.
- The six small form factor (SFF) database drives are located in the front of the base enclosure.
- Two IEC 320 C13 to IEC 320 C14 power cables
- These 2.3-foot (0.7-meter) long power cables are used to connect the power supplies in a base enclosure to two different PDUs.
Expansion enclosure hardware
The expansion enclosures have a main bay and a controller bay. The main bay holds most of the drives. The controller bay holds the I/O modules and some additional drives.
Each expansion enclosure includes the hardware listed below.
- Rail kit
- The rail kit, with left and right rails, is used to mount the expansion enclosure in a rack. The expansion enclosure rail kit includes inner mounting rails that attach to the expansion 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 expansion enclosure to the PDUs, and the SAS cables that connect expansion enclosures to other enclosures. The cable management arm also keeps the cables securely connected to the expansion enclosure when the expansion enclosure is pulled partway out of the rack for service.
- The cable management arm comes with two brackets, one that attaches to the expansion enclosure and one that attaches to the right outer mounting rail.
- 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 2000W redundant power supplies at the rear of the expansion enclosure provide power for the expansion enclosure.
- 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 S32 Nodes located in EU member countries.
- Four rear fans
- The four fans at the rear of the expansion enclosure provide cooling for the drives and SAS expanders in the main bay.
- Data drives
- These 10TB, 16TB, 20TB, or 24TB SAS hard disk drives (HDDs), with drive carriers, store object data and object and system metadata. An expansion enclosure holds 42, 74, or 106 data drives, 10 in the controller bay and the rest in the main bay.
- Two I/O modules
- The two I/O modules, located in the controller bay, enable communication with the drives in the 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 S32 Node.
- Eight SAS expanders
- The eight SAS expanders in the main bay connect the I/O modules 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 I/O modules to 24 drives. The other SAS expander in each pair connects the other I/O module to the same 24 drives.
- Two IEC 320 C19 to IEC 320 C20 power cables with left-angle connectors
- 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
- 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
- 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 S32 Node includes the hardware listed below.
- One CPU
- The CPU provides the processing power for the server module.
- Four 64GB memory cards
- These memory cards provide a total of 256 GB of RAM.
- Two 512GB M.2 NVMe SSDs
- The two mirrored SSDs store the HCP S Series operating system (OS) and store logs and software used by the S32 Node.
- Two 25/10Gb SFP28 ports
- The two 25Gb/10Gb SFP28 ports are used for the access network, which provides external access to the S32 Node for data access and, optionally, management purposes.
- Two 1Gb Ethernet ports
- The server module has two 1Gb Ethernet ports. One port is used for the management network, which provides external access to the S32 Node for management purposes. The other port is unused.
- Two SAS ports
- The two SAS ports are used to connect the server module to the I/O modules on the first two expansion enclosures.
- One four-port SAS PCIe card (optional)
- Three of the four ports on the SAS PCIe card are used to connect the server module to I/O modules on expansion enclosures when the S32 Node has more than two expansion enclosures. The fourth port is unused.
- Two USB 3.0 ports
- The USB ports let you connect USB devices to the server module. A USB hub is required for connecting more than two USB devices to the server module at the same time.
- One serial port
- The serial port lets you connect a laptop computer to the server module at the customer site for the purpose of reinstalling the HCP S Series OS and software or performing other service functions.
- One Micro HDMI port
- The Micro HDMI port lets you connect a VGA monitor to the server module by means of a Micro HDMI to VGA adapter. The monitor is used, for example, to display the server module console during the installation of the HCP S Series OS and software.
- Airflow baffle
- The airflow baffle directs airflow to cool components in the server module.
Additional hardware
Each S32 Node comes with the additional hardware listed below.
- One Micro HDMI to VGA adapter
- Used for connecting a VGA monitor to the Micro HDMI port on a server module
- One four-port USB hub
- Used for connecting multiple USB devices to a server module at the same time
- One USB flash drive
- Used by authorized service providers to perform maintenance procedures at the customer site
- One serial cable
- Used for connecting a laptop computer to a server module or I/O module
