This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM System Storage® DS8870 storage system. The book provides reference information to assist readers who need to plan for, install, and configure the DS8870.
The IBM System Storage DS8870 is the most advanced model in the
IBM DS8000® series and is equipped with IBM POWER7® based

1 TB of cache. The DS8870 also features enhanced 8 Gbps device
adapters and host adapters. Connectivity options, with up to 128
Fibre Channel/IBM FICON® ports for host connections, make the
DS8870 suitable for multiple server environments in open systems
IBM System z® environments.
The DS8870 supports advanced disaster recovery solutions, business continuity solutions, and thin provisioning. All disk drives in the DS8870 storage system have the Full Disk Encryption (FDE) feature. The DS8870 also can be integrated in a Lightweight Directory Access Protocol (LDAP) infrastructure. The DS8870 is equipped with high-density storage enclosures and can be equipped with solid-state drives (SSDs).
The DS8870 can automatically optimize the use of each storage tier, particularly SSDs through the IBM Easy Tier® feature, which is available at no extra charge. With Licensed Machine Code 7.7.10.xx.xx, Easy Tier offers new features, still at no charge.
