IBM Redbooks Product Guide
Today's global organizations depend upon the ability to unlock business insights from massive volumes of
data. Now, with IBM FlashSystem 900, they can make faster decisions based on real-time insights and
unleash the power of the most demanding applications, including online transaction processing (OLTP)
and analytics databases, virtual desktop infrastructures (VDIs), technical computing applications, and
cloud environments.
Easy to deploy and manage, the IBM FlashSystem 900 is designed to accelerate the applications that
drive business. Powered by IBM FlashCore™ Technology, IBM FlashSystem provides the following
characteristics:
Extreme performance with IBM MicroLatency™ delivers 90 µs write latency and 155 µs read latency
z
Macro efficiency lowers operating costs and increases efficiency of IT infrastructure by using much
z
less power and space than traditional hard disk drive (HDD) and solid-state disk (SSD) solutions
Enterprise reliability protects critical assists with two-dimensional RAID protection, IBM Variable
z
Stripe RAID, redundant and hot-swappable components, and concurrent code loads
FlashSystem 900 can be configured in capacity points as low as 2.4 TB usable after RAID 5 protection.
Coupled with 10 Gbps iSCSI, FlashSystem is positioned to bring extreme performance to small and
medium businesses (SMBs) and growth markets. Figure 1 shows FlashSystem 900.
Figure 1. FlashSystem 900
At the heart of FlashSystem 900 is IBM FlashCore Technology, which consists of the following three key
elements:
Hardware-accelerated architecture that is engineered for flash, with hardware only data path
z
IBM MicroLatency modules that are designed for low latency, density, and reliability
z
IBM Advanced Flash Management that improves MLC flash endurance 9x over standard
z
implementations without sacrificing latency
