Slide 1: The Best Storage Virtualization Platform on the Planet that your Competitors will die for Hu Yoshida VP and CTO Hitachi Data Systems Sun Storage Academy – APAC August 2007
Slide 2: The Dynamics of Storage Growth • Storage growth rate is compounding • Regulations and disaster recovery drive longer retention, with redundant copies • Transaction access rates growing faster than capacity for operational data • Technology changes faster than capitalization rate • Utilization of storage is still fairly low 30% • Many companies are approaching the knee of the growth curve Capacity Growth Rate A refresh cycle follows 3 to 5 years behind
Slide 3: Who Took My Storage? Lead Time Buffer Stranded STORAGE RAID Overhead Copies 3 to N ALLOCATED/Unused Data
Slide 4: HW Costs Are Only Part of the TCO Iceberg… Device Migration Backup and Recovery Management Cost Scheduled Down Time Change Management Environmental Lead Time Buffer Stranded STORAGE The ratio of Management to hardware costs are 2:1 to 4:1 or more As a result the Cost of IT is not tracking to Revenue Hardware Costs Copies 3 to N ALLOCATED/Unused Data
Slide 5: Outdated Storage: 20 Year Old Architectures • Expensive High Function Monolithic Storage • Lower Cost, lower function, Modular Storage • 20-year-old architectures that were designed for: > > > Direct attached storage – No sharing Two Shift Operations – Maintenance widows GBs of Capacity – Easy to manage and migrate
Slide 6: Niche Storage Application Products Create Islands of Storage CAS Nearline RISS AXIOM NAS InServ S800
Slide 7: What Happened to the Promise of SAN? • SAN promised consolidation through the elimination of islands of storage • Ten Years later the utilization of storage is still about 20% to 30% What happened? • SAN Networked servers to storage but left the islands of storage • Storage systems are not networked to work together • Storage systems are still provisioned separately • There is no data mobility between storage systems
Slide 8: Control Unit Virtualization: The key Enabler • Only storage controller based virtualization: > Provides common storage and NAS Mainframe Apps CAS VTL data services for all heterogeneous storage and application requirements WAN > Adds no complexity or latency > Is not limited to SAN connection > Preserves end-to-end security > Enables seamless integration of future capabilities > Provides data mobility that is transparent to the application
Slide 9: External Storage Virtualization Through The ST9900 Control Unit HOST HBA Port Target Port Host View Devices VDEV ELUN ELUN — LUN that is mapped to a LUN in an external storage device LUN LUN LUN LUN LUN LUN LUN USP Storage Controller VDEV LDEV LDEV LDEV Internal Devices LDEV LDEV LDEV LDEV External Port Mapped Mapped Target Port USP Internal Storage HDD Array Group External Storage LUN LUN
Slide 10: Volume Migration in a ST9900/ST9985 • Volume Migration is done in the controller cache • Data that has not been moved yet can be accessed from the S-Vol cache image • Information in the control store keeps track of where the data resides. • No impact to the SAN switches or to the host • Provides non-disruptive migration between multi tiers of storage
Slide 11: Dynamic Provisioning Software • Optimize Storage Capacity by provisioning only what is used • Optimize Storage performance by spreading the I/O across more arms • Simplify Management by allocating what is asked for and automatically provisioning only what is used • Simplify performance tuning by spreading the I/O across all the disks in the Pool Servers HDP Volume (Virtual LUN) HDP Pool LDEVs LDEVLDEVLDEVLDEVLDEVLDEVLDEVLDEV Array Groups/Disk Drives
Slide 12: Gartner – Thin Provisioning is Revolutionary "Thin provisioning coupled with virtualized back-end disks improves staff productivity by simplifying storage provisioning and eliminating most tuning activities associated with solving performance problems."
Slide 13: Different Approaches to Storage Virtualization “SAN’s are the third leading cause of application Mapping Mapping failures, with an average outage of 25.5 Table hours” Table Disaster-Resource.com 2006
Slide 14: All Storage Controllers Do Virtualization Today • Host servers talk to cache images of disks in a storage controller - not to the actual physical disk • Storage Controllers create a Logical Unit Number (LUN) from a Redundant Array of Independent Disks (RAID) • Controllers have years of proven data mobility functions like snap copies, remote replication, Copy on Write • The storage control unit is the best platform for virtualization of external storage > Because it has all the information needed to virtualize storage
Slide 15: Why Don’t Other Storage Vendors Do the Same? No other Storage Controller has a Dynamic Cache Architecture • Dynamic cache enables changing storage configurations without disruption to applications • Virtual ports enable physical ports to support thousands of host connections • Host Storage Domains provides each virtual port with it own address space for safe multitenancy • Logical Partitioning insures QoS for critical applications by partitioning resources like cache • Switch architecture insures availability by switching around failures and hot spots
Slide 16: The Evolution of Hitachi/SUN Storage Virtualization 1995 Global Cache with separation of control and data 2000 Introduction of first scalable crossbar switch architecture 2002 Introduction of Virtual Storage Ports and Host Storage Domains with second generation of crossbar switch architecture 2003 Introduction of Storage Area Management and heterogeneous (external) storage management 2003 Cross-System Copy is introduced to move data between Lightning V and Thunder V without host intervention 2004 ST9900 enables large-scale virtualization of externally attached storage behind third generation crossbar switch architecture ST998v Increased performance and Dynamic Provisioning 2007
Slide 17: Security Features • Separation of Control and Data – Administrators can not touch data • Audit Logging – Transaction format, NTP, SYSLOG • Management Interfaces – HTTP/SSL and server side certificates – Roles based Access for admin, auditor, Account manager – Anti Virus • Data Protection Feature – WORM capability with shredding • Privacy Feature – Data Shredding with tiered storage movement Security is integrated in the Architecture Not bolted on • Secure multi-tenancy – Private Virtual Storage Machines- Logical partitioning – Virtual Ports and Host Storage Domains • FC-SP CHAP - End to End authentication • Encryption with Appliances
Slide 18: Taking Back Your Storage Lead Time Buffer Lead Time Buffer Virtualization and Dynamic migration Virtualization and logical partitioning Stranded STORAGE Stranded STORAGE RAID Overhead Reduce RAID overhead with RAID 5 Copies 3 to N Dynamic Provisioning and lower cost tiers Dynamically migrate between RAID types ALLOCATED/Unused Data Data Dynamic Provisioning Reduce cost with lower tiers RAID Overhead
