Disk enclosure connection guidelines
• Expansion disk enclosures can be connected to an operational MSA Storage Array, see the HPE MSA
1050/2050/2052 Best Practices Guide.
• Mini-SAS to Mini-SAS 0.5 m (1.64 ft) cables are provided with all supported expansion Disk Enclosures.
• The maximum length cable supported for connecting disk enclosures is 2 m (6.56 ft).
• Cables longer than those supplied with the disk enclosure must be purchased separately. For a list of
cables available from HPE, see the HPE MSA 2050/2052 QuickSpecs.
• The maximum number of enclosures supported with an MSA 2050/2052 solution is eight (one MSA
2050/2052 and up to seven expansion disk enclosures).
Example MSA 2050/2052 disk enclosure connections
MSA 2050/2052 firmware supports both fault-tolerant and straight-through SAS cabling to cascaded disk
enclosures. For more information about these cabling schemes and for additional cabling examples, see the
HPE MSA 2050/2052 Cabling Configuration Guide.
Connect the MSA Controllers to data hosts
Direct-connect and switch-connect environments are supported. For direct-connect configurations, connect
cables from the MSA controller host ports to the host. For switch-connect configurations, connect cables from
the MSA controller host ports to the switch ports and from the switch ports to the hosts.
For cabling examples, including connecting directly to a server, see the HPE MSA 2050/2052 Cabling
Configuration Guide.
MSA 2050/2052 connection guidelines
• No host interface cables are shipped with MSA 2050/2052 Storage Systems. For a list of cables available
from HPE, see the HPE MSA 2050/2052 QuickSpecs.
• In direct-connect deployments, connect each host to the same port on both of the MSA controllers.
• In switch-connect deployments, connect an MSA Controller A port and the corresponding MSA Controller
B port to one switch, and connect a second MSA Controller A port and the corresponding MSA Controller
B port to a separate switch.
Connect the MSA Controller to a remote management host (recommended)
A remote management host directly manages systems out-of-band over an Ethernet network.
If a remote management host is included in your environment, connect an RJ-45 Ethernet cable from the
network management port on each MSA 2050/2052 controller to a switch that your management host can
access (preferably on the same subnet).
Connect two MSA storage systems to replicate volumes (optional)
HPE MSA Remote Snap Software is an optional licensed disaster-recovery utility that performs asynchronous
(batch) replication of block-level data from a volume on a primary MSA storage system to a secondary volume
