Software
The following functions are included with every ThinkSystem DS4200:
Intelligent Real-time Tiering for HDDs : Storage tiering helps optimize storage use with intelligent
data placement to improve system performance, reduce costs, and simplify management. The
DS4200 automatically and dynamically moves frequently accessed data to higher performing HDDs
in the system without manually creating and managing storage tier policies.
All Flash Array (AFA) capability: Meets the demand for higher speed storage and provide higher
IOPs and bandwidth with lower power usage and total cost of ownership than hybrid or HDD-based
solutions.
RAID levels 0, 1, 5, 6, and 10 : Provide the flexibility to choose the level of data protection required.
Virtualized storage pools: Enables rapid, flexible storage provisioning and simple configuration
changes. Stored data is distributed across all drive groups in the pool (wide striping) which helps
improve performance, lower latency, and achieve higher volume capacities. When a new drive
group is added to the pool, the system performs automatic rebalancing to utilize all drives in the
pool for better performance.
Thin provisioning: Optimizes efficiency by allocating drive storage space in a flexible manner
among multiple applications, based on the minimum space required by each application at any
given time. With thin provisioning, applications consume only the space they are actually using, not
the total space that has been allocated to them, which allows clients to purchase storage they need
today and add more as application requirements grow.
SSD Read Cache: An extension of the controller's cache to improve performance of read-centric
workloads
