  1. Storage Overview And Architecture Arvind Shrivastava

  2. Enterprise Network Storage Architecture Unbounded performance and capacity Network Attached Storage Direct Attached + Software Core Technology Unprecedented flexibility Services + Storage Area Network Simplified management The lowest total cost of ownership =

  3. Direct Attached Storage(DAS) • Low Cost Solution • Simple to Configure • De-Centralized Storage • No Storage Consolidation • No High Availability • Low Performance

  4. Network Attached Storage(NAS) • Heterogeneous Environment • Centralized Storage • Low Performance • Limited scalability • Network Congestion during backups & Restore • Ethernet Limitations

  5. Storage Area Network • Heterogeneous environment • Centralized Storage Management • High Degree of Fault Tolerance • Best and superior performance • Storage Consolidation • Fast and efficient backups and restores • Dynamic Scalability • Expensive solution for small setups

  6. SAN V/s NAS

  7. Mid-Range Storage Features • • Excellent ease of use • • Virtualization • • Dynamic virtual disk expansion • • Business Copy functions • • Continuous Access functions • • High availability features • • High, middle*, and low models and configurations • • Multiple operating system support • • Single pathing support for all operating systems • • Coexistence with heterogeneous configurations

  8. Buisness copy Overview

  9. Continuous Access-Overview

  10. Flex Copy Concept Cost-effective, external point-in-time copies • Features • Allows use of low end storage for low-cost point-in-time copies of production data • Point-in-time copy to and restore from Low end 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 C1 Low end storage P Enterprise storage

  11. Product Positioning

  12. Additional Features EVA4000/6000/8000 • Additional features unique to the second generation EVA • • New controllers with improved performance, higher capacity • support, larger cache, more FC ports • • Up to 200TB of presented capacity (versus 35TB for the first • generation EVA) • • Support for 1024 LUNs (first generation EVA was 512) • • Support for active-active failover using multipath software • for all operating systems • • Increased support for boot from SAN (AIX, Solaris) • • Direct Connect support for Windows • • Additional CA functionality • • Support for native HBAs and HBA drivers • • Additional snapshot and snapclone functionality

  14. Storage backup Overview And Architecture Arvind Shrivastava

  15. BACKUP SOFTWARE • What is it? • Software that provides automated data protection for businesses with 24x7 availability needs. • What does it do? • Data Protection: copies data onto a storage device, so that in case of a need (loss, corruption, disaster), data can be easily recovered and made accessible. • Media management: easily manages the library catalogues to keep track of all media and copies of data for fast recovery. • Most important features: • Automated backups that scale from small workgroups to multi-site, heterogeneous SAN & NAS environments with thousands of servers. • Fully-integrated Zero-Downtime backup with Instant-Recovery.

  19. How to choose between tape drives and tape libraries servers

  21. Tape drives – Speeds and feeds - Comparison Complied by Ranganath Sadasiva

  22. Features • Features Required in any Backup software • Advanced backup to disk • Oracle/SAP Integrations • Zero Downtime Backup • Split mirror • Snapshot • Snapclone • Filesystem / application backup on inactive MC/SG node

  23. Overview – Advanced backup to disk • Why backup to disk? • Benefits • Fast random access allowing: • Fast single file restore • Space efficient backup • Instant recovery • e.g. switching for recovery instead of restoring data from tape • Faster restore of backup chains • No tape streaming problems • Ideal for RAID 5 • Easy to detect disk failures • More protected, e.g. it’s not easy to steal a disk

  24. Advantages of ZDB • The advantages of using Data Protector Oracle ZDB integration are the following: • • ZDB reduces the performance degradation of the application system. • • The tablespaces are in backup mode (online backup) or the database is shut down (offline backup) only during the short period required to create a replica (split the mirror disks or create snapshots). • • The time to create a replica is significantly reduced. Following its creation, tape backup can be created on the copied data, at leisure , using a separate backup system. • The Data Protector Oracle ZDB integration offers online and offline backup of your Oracle Server System (application system).

  25. BACKUP CONCEPT-SPLIT MIRROR BACKUP

  26. ZDB Setup • True online backup for integrated applications • Split mirrors may used for instant recovery or resynced • No performance impact on applications during backup • Mirror synchronization before or after backup • Automatic mirror rotation • API based integration XP Application host P M M M 0 1 2 Backup host P – primary LDEV M – mirror copy (MU0-2)
