54 Configuring Storage
Dell EqualLogic PS Series
Dell EqualLogic PS Series iSCSI arrays simplify storage deployment by
offering high performance, reliability, intelligent automation, and seamless
virtualization of a single pool of storage.
The foundation of an EqualLogic storage array is a PS Series group — an
iSCSI SAN including one or more PS Series storage array members connected
to an IP network and managed as a single system. Each array has fully
redundant hardware and up to three active network connections for
maximum bandwidth. Integrated virtualization firmware provides:
• Seamless scalability
• Automatic RAID configuration and spare disk configuration
• Automatic network, performance, and capacity load balancing
The Dell EqualLogic PS5000E line spans from 2 to 16 TB in capacity in a
single array, utilizing SATA drives ranging in size from 250 GB to 1 TB.
PS5000X arrays offer 6.4 TB of raw storage capacity utilizing 400 GB (10,000
RPM) Serial Attached SCSI (SAS) disk drives. PS5000XV arrays offer 2.3 TB
or 4.8 TB of raw storage capacity utilizing 146 GB/300 GB (15,000 RPM) SAS
disk drives. PS5500E arrays utilizes forty-eight 500 GB/1 TB (7200 RPM)
SATAII disk drives to deliver 24 or 48 TB of raw capacity in a 4U enclosure.
All PS Series models have dual active/passive controllers with three 1-GbE
ports per controller for a total of six 1-GbE ports.
By default, the physical network interface on which the XenServer
management interface is configured is chosen to route the IP storage traffic.
However, a different physical interface or a bond of two network interfaces
can be configured to segregate storage traffic from management traffic. See
"High Availability Configuration and IP Storage Traffic Segregation" on
page 67 for more details on specific configuration steps.
