IBM Systems and Technology Group EMC Invista Host Attachment § Attaches to Linux, UNIX and Windows SAN Switches and Directors § External storage must be SAN attached § Requires special “intelligent” SAN switches that can run in-band software Invista Appliances § Pair of appliances manage mapping tables § Communicate to intelligent SAN switches via IP network Storage § § 72 Internal storage: NONE External storage: variety of disk systems, expected to have RAID protection © 2008 IBM Corporation
IBM Systems and Technology Group What you really need to know about Invista § Limited Interoperability § § § – Limited to devices supported by EMC Power. Path, HP PV-Links and Symantec DMP Invista Control Path is an “out of band” appliance – CPC is Intel-based hardware running Windows OS – If you lose both CPC’s… you lose access to data – No scalability for the CPC – 2 or 4 DCP on intelligent switches CISCO SSM, or Brocade AP 7600 B/FA 4 -18 Poor Performance and Scalability – No cache! No SPC-1 or SPC-2 benchmarks! – Add 30 µseconds on all IOs – Scalability: 8000 Virtual Volumes and Storage elements; 800 initiators (host HBAs) Management – Not integrated with SMI-S, Limited integration with EMC Control Center – Web-based GUI and CLI – No reporting tool Unlike IBM SDD, EMC Multipath is not free of charge Array based Mirroring – Licence and flexibility issue – Mirroring is done by SVC Product was GA in Dec. 2005 EMC has only announced a single customer reference and claims about 200 cutomers 73 © 2008 IBM Corporation
IBM Systems and Technology Group What you really need to know about Invista – Cont. § Limited Advanced Copy Services – Data migration and Volume Cloning only – Invista does not handle Remote Replications – Invista depend on external replication solutions Disk array replication Result in array and vendor bindings – DMX-DMX, CLARii. ON-CLARii. ON, no intermix – Other replication solutions like EMC Recover. Point – Not integrated into Invista, separate solutions – Invista and Recover. Point cannot run on same AP 7420/SSM blade, need dedicated hardware – Recover. Point and Invista (Recover. Point = Kashya) Virtualization solution 74 Virtualization solution © 2008 IBM Corporation
IBM Systems and Technology Group Review questions • • 75 How is SVC priced and who is the major competitor? • It is priced by TB and EMC Invista • It is tier priced and HP True Copy • It is processor based priced and HDS Tagamastore • One time charge and Sun Planet What the 4 major components of TPPC? • Date, Disk, Fabric, and Replication • Data, disk, fabric, provisioning • Disk, tape, fabric, and virtualization • Disk, energy management, fabric, and virtualization Tivoli Storage Manager support the ability to set policies for storage of data based on access needs, performance, and cost. What is that function called ? • Data Deduplication • Hierarchical Storage Management (HSM) • Storage Virtualization • Global Mirroring Name 2 key benefits of SVC • Data deduplication and low price • Non disruptive data migration and utilization of non IBM replication services • Non disruptive data migration and elimination of non IBM replication services • Price and support of tape systems © 2008 IBM Corporation
