Dell PowerVault MD3860i Storage Arrays: руководство по обслуживанию

Technical Specifications

Table 1. Physical Disks. This describes Physical Disks
Physical disks Up to sixty 3.5 inch or 2.5 inch SAS or nearline SAS physical disks or 2.5 inch SAS SSDs
Table 2. RAID Controller Modules. This describes RAID Controller Modules.
RAID controller modules Two hot-swappable modules with temperature sensors

4 GB or 8 GB of cache per controller

Dell PowerVault MD3860i storage arrays Provides host-to-controller 10 Gbps iSCSI connection and two 12 Gbps SAS connections
Table 3. Expansion Modules. This describes Expansion Modules.
Dell PowerVault MD3060e expansion enclosures Supports 120 physical disks, in addition to 60 physical disks in the RAID enclosure

Redundant path connectivity provides redundant data paths to each hard drive

  • NOTE: Support for 180 physical disks is a premium feature and requires activation. The maximum number of physical disks supported without using the premium feature is 120.
  SAS connectors Two SAS IN ports to connect hosts

One SAS OUT port for expansion to an additional PowerVault MD3060e expansion enclosure

  • NOTE: SAS connectors are SFF-80644 compliant.
  Serial connector (debug port) Six pin port
  • NOTE: For technical support use only.
Table 4. Back-Panel Connectors (Per RAID Controller Module). This describes Back-Panel Connectors (Per RAID Controller Module)
  SAS connectors

Two SAS IN ports to connect hosts

  • NOTE: SAS and iSCSI connections to the same host is not supported.
  • NOTE: SAS and connections to the same host is not supported.

Two SAS OUT ports, it is recommended that you use the first port for expansion to an additional PowerVault MD3060e expansion enclosure. Only one expansion port is supported at any given time.

  • NOTE: SAS connectors are SFF-8644 compliant.
  Serial connector (debug port)

One 6-pin mini serial port

  • NOTE: For technical support use only.
  Management Ethernet connector One 100/1000 Mbps Ethernet connection for out-of-band management of the enclosure and the second Ethernet port is reserved.
  iSCSI connectors Two 10 Gbps iSCSI IN connectors to connect hosts
  • NOTE: Directly attaching to the FC ports is not supported. The host connection must use a FC switch.
Table 5. Power. This describes power.
AC power supply (per power supply)  
  Wattage 1755 W
  Heat dissipation (maximum)
  • NOTE: Heat dissipation is calculated using the power supply wattage rating. The heat dissipation values are for the entire system which includes chassis and two controllers.
5988 BTU/hr
  Voltage
  • NOTE: This system is also designed to be connected to IT power systems with a phase to phase voltage not exceeding 230 V.
220 V AC, autoranging, 50 Hz/60 Hz
Battery 6.6 V DC, 1100 mAh, 7.26 W Lithium ion battery
