XP12000 Client Host Interface Processors (CHIPs)• Client Host Interface Processors (CHIPs) provide connections to

hosts or servers and come in pairs− Maximum of four pairs per XP 12000 system− Fibre Channel

• 16 and 32-port 1- to 2-Gbit Auto sensing Fibre Channel in both short and long-wave versions

− ESCON• 16-port ExSA Channel (ESCON compatible)

− FICON• 8 and 16-port 1- to 2-Gbit auto-sensing FICON in both short and long-wave versions

XP12000 Array Control Processor (ACP)

• The ACP performs all data movement between the disks and cache memory− The ACP also provides data protection through RAID 1 mirroring and RAID 5 parity

generation− Each ACP provides 8 redundant 2 Gbps FC-AL loops (16 loops total per pair) and

supports up to 64 dual ported drives per loop

• Maximum of four ACP pairs per XP 12000 system− ACPs are configured in pairs for redundancy

• Choice of standard performance (4 microprocessors) or high performance (8 microprocessors) ACP pairs− Standard performance and high performance ACPs can not be mixed in a system

Best for…•Multi-Site implementations

•Update data (Sidefile) is stored in Cache•Primary side initiates updates•1:1 configurations onlyStrengths•Potential for better data currencyBest for…•1:1 implementations

Flex Copy XPFeatures

− Allows use of HP MSA storage for low-cost point-in-time copies of production data

− Point-in-time copy to and restore from MSA storage

− CLI or GUI Configuration

Benefits− Reduced TCO in mixed product/non-

production − Offloads production data from

secondary operations− Allows for distributed remote data and

hi performance two-stage backup/archive configurations

Cost-effective, external point-in-time copies

Storage Partition XPCache Partition XPEasy Secure Consolidation• logically partition the

resources in an XP12000• create independent

configurable and manageable “sub arrays”

• Partitions Cache or Array (cache, storage, port) resources− Allows array resources to be

focused to meet critical host requirements

− Allows for service provider oriented deployments

− Array partitions are independently & securely managed

− Can deploy in an mixed deployment (Cache, Array, Traditional)

Continuous Access XPJournaling CA

Operation1. Primary Site server writes to Cache and Data Volumes, I/O is immediately acknowledged

by array2. Primary Journal Volume is asynchronously updated with primary data changes (change

data and metadata)3. Remote Site XP array reads Primary Journal Volume changes, and then updates Remote

Journal Volume4. Remote Site Journal Volume changes are applied against the Remote XP Array Copy

– History of write data is stored in journal on disk instead of in sidefile in cache memory– Data is copied by means of a special, more efficient read I/O initiated by the remote

array– Journal can be shared between multiple sites (not in 1st release)– no performance impact to host if link bandwidth is exceeded for extended periods of

time– Journal is not limited by cache size and does not limit available cache to other

operations– I/O sequence maintained during temporary link failures and recovery
