IBM Flex System x240 Compute Node (E5-2600) 17
These features are described as follows:
RAID 6 Upgrade (90Y4410)

Adds support for RAID 6 and RAID 60. This is a Feature on Demand license.
Performance Upgrade (90Y4412)

The Performance Upgrade for IBM Flex System (implemented using the LSI MegaRAID FastPath
software) provides high-performance I/O acceleration for SSD-based virtual drives by exploiting an
extremely low-latency I/O path to increase the maximum I/O per second (IOPS) capability of the
controller. This feature boosts the performance of applications with a highly random data storage
access pattern, such as transactional databases. Part number 90Y4412 is a Feature on Demand
license.
SSD Caching Enabler for traditional hard drives (90Y4447)

The SSD Caching Enabler for IBM Flex System (implemented using the LSI MegaRAID CacheCade
Pro 2.0) is designed to accelerate the performance of hard disk drive (HDD) arrays with only an
incremental investment in solid-state drive (SSD) technology. The feature enables the SSDs to be
configured as a dedicated cache to help maximize the I/O performance for transaction-intensive
applications, such as databases and web serving. The feature tracks data storage access patterns
and identifies the most frequently accessed data. The hot data is then automatically stored on the
SSDs that are assigned as a dedicated cache pool on the ServeRAID controller. Part number
90Y4447 is a Feature on Demand license. This feature requires at least one SSD drive be installed.
Internal drive options
The 2.5" drive bays support SAS or SATA hard disk drives (HDDs) or SATA solid state drives (SSDs).
