The DS5020 supports configurations of FC disks with or without Full Disk
Encryption (FDE), SATA disks with SATA-FC interposers, solid state disks (SSD),
FC-SAS disks (SAS disks with FC-SAS interposers), or a mix of disk drives. To
install FDE disks in a DS5020, you must purchase the Full Disk Encryption option.
In addition, the FC-SAS disk drives are formatted with 520 byte sectors, and
support T10 Protection Information (T10 PI) capability for the transfer of drive data.
Advanced DS5020 storage management, copy service options, and optional
advanced disaster recovery functions are available for the DS5020, including
FlashCopy
®
, VolumeCopy, and Enhanced Remote Mirroring. To install the SSD or
FC-SAS disks in the DS5020, the minimum versions of controller firmware installed
in the DS5020 must be 7.70.xx.xx or 7.77.xx.xx, respectively.
The DS5020 supports up to four hosts in a redundant direct-attached Fibre Channel
configuration. When using Fibre Channel or Ethernet switches, you can redundantly
connect up to 512 hosts to the DS5020 FC and iSCSI host ports. You can order up
to 128 storage partitions for the DS5020.
DS5020 storage subsystems are equipped with ac power supply and fan units that
support both NEBS/ETSI operating environments and standard IT and office
environments.
The DS Storage Manager client is also available for the DS5020. This storage
management software is designed to help centralize storage management, help
simplify partitioning of the DS5020 storage subsystem, and strategically allocate
storage capacity to maximize storage space.
