Support for 512-GB and 256-GB Performance Acceleration Module (PAM
II)
Data ONTAP 8.0.1 7-Mode and later Data ONTAP 8.0.x 7-Mode releases
support a PCIe-attached Performance Acceleration Module (PAM II also
known as Flash Cache module) that uses Flash technology.
The addition of PAM II optimizes the performance of random read-intensive
workloads such as file services, messaging, virtual infrastructure, and OLTP
databases without using more high-performance disk drives.
For more information about PAM II modules supported with your storage
system models, see IBM System Storage N series Introduction and Planning Guide.
Support for SSDs
Data ONTAP 8.0.1 7-Mode and later Data ONTAP 8.0.x releases support
solid-state disks (SSDs). SSDs are flash memory-based storage devices that
provide better overall performance than hard disk drives, or HDDs, which are
mechanical devices using rotating media.
For more information about SSDs, see the Data ONTAP 8.0 7-Mode Storage
Management Guide. For information about which storage system models
support SSDs, see IBM System Storage N series Introduction and Planning Guide.
Support for 900-GB SAS disks
In Data ONTAP 8.0.2 and later releases, 900-GB disks are supported for
EXN3500 SAS storage expansion units. These are performance disks (rather
than capacity disks) and their speed is 10K.
Supported tape drives
Data ONTAP 8.0.1 and later releases support Quantum LTO-4, Quantum
LTO-5, Hewlett-Packard LTO-4, Hewlett-Packard LTO-5, and IBM LTO-5 tape
drives.
Support for 3-TB SATA disks
In Data ONTAP 8.0.2 and later releases, 3-TB SATA disks are supported for
the SAS disk connection type.
The 3-TB SATA disks have a right-sized capacity of 2,538 GB (where GB =
1,000*1,024*1,024), and 5,198,943,744 available blocks (sectors).
Support for 2-TB SATA disks
In Data ONTAP 8.0 and later releases, 2-TB SATA disks are supported for both
the SAS and FC disk connection types. With these larger disks and 64-bit
aggregates, you can create larger aggregates before being affected by spindle
and aggregate size limits.
