  1. 校園及企業資訊服務、安全、維運 Disaster Recovery備援 Virtual Tape Library虛擬磁帶機 Continuous Data Protection 連續數據保護 陳文賢 (eric.chen@falconstor.com) GM, APAC Chairman, Storage Networking Industry Collaboration (SNIC)

  2. At-A-Glance • Headquartered in Melville, New York. Large RD/Support center in Taiwan • Providing Network Storage Software to Optimize the Availability (Recovery) of Business-Critical Data • Innovative Technology OEMed by Major Industry Players • EMC, HP, IBM, Intel, McData/Broacade, Sun/StorageTek, Huawei-3Com, KEL, Acer, NEC • Public Company (NASDAQ:FALC) • Our idea is to use the Storage Networking Technology to provide Business Continuity Solutions: Storage Consolidation, Virtualization, Replication, Snapshot, Virtual Tape Library, etc.

  3. FalconStor’s Unified Storage Architecture Comprehensive Storage Services Snapshot Mirroring TimeMark Replication Zero-Impact-Backup WORM Disk NAS Disk iSCSI Disk FC Disk SAN Disk DLT LTO SQLserver Oracle Exchange SAP Notes Snapshot Agent Snapshot Agent Snapshot Agent Snapshot Agent Snapshot Agent IB CIFS NFS iSCSI FC 100% modular “Protocol-Independent” Host Connectivity Layer 100% modular “Hardware-Agnostic” Storage (Disk, Tape) Abstraction Layer I/O Load Balancing, Controller/Path Fail-Over/Fail-Back 100% modular

  4. IPStor for your Data Center & DR Site

  5. Traditional Disaster Recovery Schemes • Costly and difficult to manage • Labor intensive • Time to recovery is very slow • Tape restore not very reliable Offsite tape storage Host-to-host replication • Multiple individual points of management • Specific software needed for every operating system • Affects host processing • Lack of database support • Example: Veritas, DoubleTake • Cannot replicate across vendor barriers: supplier lock in • Costly channel extenders • May have limited OS support • Lack of database support • Example: EMC Disk array-to-disk array replication

  6. IPStor Disaster Recovery: Asymmetric and Many-to-One Key Benefits • Supports all open operating systems from a single console • Reliable recovery from disk • Database integration • No impact to host processing • Centralized services, easy to manage • Cost effective, low TCO • Works across all vendor storage devices • Rapid recovery of applications

  7. VTL (Virtual Library) and CDP (Continuous Data Protection)

  16. SIR (available in end of Q4,2006) • Integrating VTL and RDE within FalconStor SIR • Transparent and non-disruptive to existing environments • Decoupling the data services layer from existing data path • Out-of-Band processing • Rapid Client-based recovery • Platform, storage, and backup software agnostic • Falconstor Single Instance Repository = Redundant Data Elimination with rapid recovery

  21. Case Studies

  22. CDP case study

  23. 東海計中導入前之架構及遭遇的問題 • 各伺服器儲存空間獨立，無單一或集中化的管理機制。 • 資料存放不均，以致不足或過剩浪費資源，而無法有效率的管理。 • 儲存設備距離限制短，不易分享。 • 資料量持續且快速成長造成空間不足或預估不夠時，擴增程序繁雜不便。

  24. 東海計中導入Storage Consolidation後之架構 • 導入項目： • 光纖通道儲域網路（FC-SAN）：包括 FC Switch、HBA、Fibre cable。 • Storage Services System：IPStor Server

  25. 東海計中導入DR後之架構

  26. 東海計中導入後之效益 • 搭配儲存空間整合架構，易集中規劃管理。 • 訂定資料備份政策可依資料性質而訂定不同方式與規則，更能配合階段性任務機動調整資料備份或同步的時間間隔。 • 以磁碟為基礎的備份機制，備份窗口短，資料復原速度快。 • 達成異地備援、磁帶異地存放的目的。 • 降低長期整體擁有成本（TCO）
