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® lineup 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 Gpbs device adapters and host adapters. Connectivity options, with up to 128 Fibre Channel/FICON® ports for host connections, make the DS8870 suitable for multiple server environments in both open systems and IBM System z® environments. The DS8870 supports advanced disaster recovery solutions and business continuity solutions and also supports thin provisioning.
All disk drives in the DS8870 storage system have the Full Disk Encryption (FDE) feature. If desired, the DS8870 can be integrated in an LDAP infrastructure.
The DS8870 is equipped with high-density storage enclosures populated with 24 small-form- factor SAS-2 drives or storage enclosures for 12 large-form-factor nearline SAS drives. The DS8870 storage subsystems can also be equipped with Solid-State Drives (SSDs).
The DS8870 can automatically optimize the use of each storage tier, particularly SSD drives through the IBM Easy Tier® feature, which is available for no extra fee.
