inch small form factor (SFF) drives in the controller enclosure; scalable up to 120 LFF drives per
system with the attachment of ThinkSystem DS Series LFF expansion units (12x LFF drives each) or
up to 240 SFF drives per system with the attachment of ThinkSystem DS Series SFF expansion
units (24x SFF drives each) to satisfy growing needs for storage capacity and performance.
Flexibility in storing data on high-performance SAS SSDs, performance-optimized enterprise SAS
HDDs, or capacity-optimized enterprise NL SAS HDDs; mixing and matching drive types and form
factors within a single system to perfectly meet performance and capacity requirements for various
workloads.
Support for self-encrypting drives (SEDs) to allow clients to secure their sensitive data and to comply
with various security regulations, when required.
Rich set of standard functions available at no extra cost, including virtualized storage pools,
snapshots, thin provisioning, rapid RAID rebuild, real-time HDD tiering, SSD read cache, and All
Flash Array (AFA).
Optional licensed functions, including higher number of snapshots for more scalability, real-time
SSD tiering for boosting IOPS performance, and asynchronous replication for 24x7 data protection
and disaster recovery.
Intuitive, web-based GUI for easy system set up and management, as well as Command Line
Interface (CLI).
Designed for 99.999% availability.
