This IBM® Redbooks® publication describes the concepts, architecture, and implementation of the IBM DS8870. The book provides reference information to assist readers who need to plan for, install, and configure the DS8870.
The IBM DS8870 is the most advanced model in the IBM DS8000® series and is equipped with IBM POWER7+™ based controllers. Various configuration options are available that scale from dual 2-core systems up to dual 16-core systems with up to 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 and 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 features high-density storage enclosures and can be equipped with flash drives. An all-flash drive configuration is also available.
The DS8870 can automatically optimize the use of each storage tier, particularly flash drives, through the IBM Easy Tier® feature, which is available at no extra charge. Easy Tier is covered in separate publications: IBM DS8000 Easy Tier Concepts and Usage, REDP-4667; IBM System Storage DS8000 Easy Tier Server, REDP-5013; IBM System Storage DS8000 Easy Tier Application, REDP-5014; and IBM System Storage DS8000 Easy Tier Heat Map Transfer, REDP-5015.
