Page 8: Overview
"Controller enclosure—rear panel layout" on page 15 "Rear panel LEDs" on page 69 The MSA 2070/2072 enclosures support virtual storage. For virtual storage, a group of disks with an assigned RAID level is called a disk group. MSA 2070/2072 enclosure user interfaces MSA enclosures are managed by the Storage Management Utility (SMU), which is a web-based application for configuring, monitoring, and managing the storage system. -
Page 9: Features And Benefits
"Connecting hosts" on page MSA SAS controllers provide four (MSA 2070/2072) high density mini-SAS (mini-SAS HD) ports per controller module. The mini-SAS HD host interface protocol uses the SFF-8644 external connector interface defined for SAS 3.0 to support a link rate of 12 Gb/s using the qualified connectors and cable options. - Page 10 NOTE The table above provides titles of related MSA documents used with this guide.

MSA 2070/2072 supports 2U24 and 2U12 chassis as controller enclosures and disk enclosures. MSA 2072 uses two SSD drives pre-installed in drive slots 1 and 2. MSA 2070/2072 controller enclosures support only MSA 12Gb disk enclosures that are described in this guide. Earlier MSA 6Gb LFF and SFF disk enclosures are incompatible. -

To observe disk LEDs during enclosure operation, you must remove the enclosure bezel. Optionally, you can monitor disk activity using management interfaces when the bezel is attached. NOTE A partial assembly view shows bezel insertion into the right ear hubcap slot. Simplified conceptual graphics illustrate the enclosure bezel attachment procedure. -

MSA 2072 enclosures These enclosures support the same disk types supported by MSA 2070 enclosures. A notable configuration exception is that for these enclosures, two SSDs are pre-installed. One SSD is installed in drive slot 1 and the other SSD is installed in drive slot 2. -
Page 15: Controller Enclosure-Rear Panel Layout
IMPORTANT HPE MSA enclosures support dual-controller configurations only. If a partner controller fails, the array will fail over and run on a single controller until the redundancy is restored. A controller module must be installed in each controller module slot to ensure sufficient airflow through the enclosure during operation. -

Page 19: Non-Volatile Memory
Supercapacitor pack To protect RAID controller cache in case of power failure, HPE MSA controller modules are equipped with supercapacitor technology, which in conjunction with internal non-volatile memory, provides extended cache memory backup time. The supercapacitor pack provides energy for backing up unwritten data in the write cache to the non-volatile memory in the event of a power failure. -

Page 37: Connecting To The Controller Cli Port
Connecting to the controller CLI port Device description The MSA 2070/2072 controllers feature a command-line interface port used to cable directly to the controller and initially set IP addresses, or perform other configuration tasks. This port employs a micro-USB Type B form factor, requiring a cable that is supplied with the system, and additional support described herein, so that a server or other computer running a Linux or Windows operating system can recognize the controller enclosure as a connected device. -
Page 38: Preparing A Windows System For Cabling To The Cli Port
IMPORTANT Although Linux systems do not require installation of a device driver, on some operating system versions, certain parameters must be provided during driver loading to enable recognition of the MSA 2070/2072 controllers. To load the Linux device driver with the correct parameters on these systems, the following command is... -

USB CLI port connection MSA 2070/2072 controllers feature a CLI port employing a micro-USB Type B form factor. If you encounter problems communicating with the port after cabling your computer to the USB device, you may need to either download a device driver (Windows), or set appropriate parameters via an operating system command (Linux). - Page 45 Use the CLI. View the enclosure LEDs. Monitor notifications With notifications configured and enabled, you can view alerts or event logs to monitor the health of the system and its components. Alerts inform the user of conditions requiring action to maintain availability and prevent potential loss of data.

Page 46: Performing Basic Steps
View the enclosure LEDs You can view the LEDs on the hardware (while referring to "LED descriptions" on page 64 for your enclosure model) to identify component status. If a problem prevents access to either the SMU or the CLI, this is the only option available. However, monitoring/management is often done using the SMU interface rather than relying on line-of-sight to LEDs of racked hardware components. -

Page 79: Weight Guidelines
The system requires voltages within minimum fluctuation. The customer-supplied facilities' voltage must maintain a voltage within the range specified on the equipment's electrical rating label. The customer facilities must also provide suitable surge protection. Site wiring must include an earth ground connection to the DC power source. Grounding must comply with local, national, or other applicable government codes and regulations. -
Page 80: Cabling Requirements
Leave a minimum of 15 cm (6 inches) at the front and back of each enclosure to ensure adequate airflow for cooling. No cooling clearance is required on the sides, top, or bottom of enclosures. Leave enough space in front and in back of an enclosure to allow access to enclosure components for servicing.
