Key Features - IBM FlashSystem 900 Product Manual

Key features

FlashSystem 900 provides extreme performance with IBM MicroLatency™, macro efficiency, and
enterprise reliability.
Scalability and performance
FlashSystem 900 has the following scalability and performance features:
IBM FlashCore technology for consistently high performance at lower cost
90us/155us read/write latency
Up to 1.1 million random read 4 K IOPS
Up to 10 GB/second read bandwidth
IBM-enhanced Micron MLC technology for higher storage density and improved endurance
Flexible interface types of Fibre Channel, Fibre Channel over Ethernet (FCoE), iSCSI, and InfiniBand
Up to 16 ports of 8 Gbps or eight ports of 16 Gbps Fibre Channel
Up to 16 ports of 10 Gbps FCoE
Up to 16 ports of 10 Gbps iSCSI
Up to eight ports of 40 Gbps quad data rate (QDR) InfiniBand
Slots for up to 12 hot-swappable IBM MicroLatency storage modules (1.2 TB, 2.9 TB, or 5.7 TB)
Configurable 2.4 - 57 TB of capacity for increased flexibility
Enterprise-class reliability features
FlashSystem 900 delivers the following enterprise-class reliability features:
Concurrent code load enables customer applications to remain online during firmware upgrades to all
components, including the IBM MicroLatency modules.
Hot-swappable IBM MicroLatency modules by way of tool-less front panel access. If a MicroLatency
module failure occurs, critical customer applications can remain online while the defective module is
replaced.
All active components are redundant and hot-swappable, including IBM MicroLatency modules, RAID
controllers, management modules, interface, batteries, fans, and power supplies.
All components are easily accessible through the front or rear of the enclosure, so IBM FlashSystem
900 does not need to be moved in the rack and no top access panels or cables need to be extended.
Two-dimensional (2D) Flash RAID, which consists of IBM Variable Stripe RAID and system-wide
RAID 5. Variable Stripe RAID technology helps reduce downtime and maintain performance and
capacity in the event of partial or full flash chip failures. System-wide RAID 5, with easily accessed hot
swappable flash modules, helps prevent data loss and promote availability.
IBM Advanced Flash Management improves flash endurance 9x over standard implementations with
IBM engineered ECC, advanced wear leveling, and proprietary garbage collection, relocation, and
block picking algorithms.
Energy and space efficiency
FlashSystem 900 has the following energy and space efficiency characteristics:
40% greater density than previous generation
4x greater capacity than competitive all-flash products
Reduced power, space, and cooling with only 625 watts typical operating power and 2U form factor
