Features
The HGST 4U60 Storage Enclosure is a high-density, scalable, and cost-effective
design, using 60 Ultrastar 3.5-inch drive modules in a 4U enclosure. It offers 2x2x4-lane
SAS 12GB/s performance, high availability (HA), and hot-swappable components. The
design is targeted towards data centers that need a dense solution with HA capabilities,
while maintaining a low power profile.
- 60 integrated Ultrastar® drive modules
− Available with 512e or 4Kn sector size (by part number)
- Host connectivity 2 x SAS QSFP+ receptacles per IO Module; optional connectivity
cables are available
− QSFP+ to HD mini SAS cables for host
- QSFP+ to QSFP+ cables for daisy-chaining2
- Hot Swappable: two power supplies (with integrated fans), drive modules, and IO
modules
- Fully compliant with SAS 3.0 specification for operation up to 12Gbps
- Cable management arm simplifies maintenance of hot-swappable CRUs
- SCSI Enclosure Services (SES-3)
- 5-year limited warranty
1 One MB is equal to one million bytes, one GB is equal to one billion
bytes, one TB equals 1,000GB (one trillion bytes) and one PB equals 1,000TB when
referring to storage capacity. Usable capacity will vary from the raw capacity due
to object storage methodologies and other factors
2 Up to 4 storage enclosures supported for daisy-chaining
SAS Expander Module
The SAS Expander Canister Module provides SAS connectivity and enclosure management
within the 4U60 Storage Enclosure. The SAS Expander Canister is not SBB 2.0 compliant
and is a custom form factor designed to support an overall length of 860mm for the
4U60 Storage Enclosure chassis.
Each SAS Expander Canister Module provides two (2) external SAS 4x QSFP+ (SFF-8436)
connectors (one "upstream" and one "downstream" for expansion), a RS-232 serial
port, and three status LEDs. Firmware in the canister provides SAS topology configuration,
enclosure management, and canister-canister synchronization. 4U60 Storage Enclosure
supports up to two SAS Expander Canisters in a single system.
The following features are available in the 4U60 Storage Enclosure SAS Expander
Canister:
- Supports native 12G connections for supporting of SAS 12G HDD and SSD
- PMC SAS 3.0 12G x 68-port SAS expander
− 60x SAS 3.0 connections to disks
- Two SAS 4x to external QSFP+ connectors
- Integrated SCSI Enclosure Service firmware
- Two SFF-8436 compliant QSFP ports , one for upstream link and one for downsream
cascading
- SCSI Enclosure Service (SES) firmware for SAS topology configuration, enclosure
management, and canistercanister synchronization
- Supports PSU output power monitor
- All target ports support spin-up control for SAS drives
- One RS232 port, through RJ45 connector, on a faceplate for product configuration
and support
