3 Data Size! Gigabytes (10*9) (Billion) of disk storage - most customers Terabytes (10*12) (Trillion) of disk storage - large customers Petabytes (10*15) (Quadrillion) of disk storage - a few customers today! Petabytes (10*15) (Quadrillion) of tape storage - large customers Exabytes (10*18) (Quintillion) of tape storage - a few accounts by 2001 Zettabytes (10*21) (Sextillion) WW digital data by IDC Yottabytes (10*24) (Septillion) - How Long will it take?

4 Topics 7 tiers of disaster recovery defined by SHARE Users group 1993 Key Technologies Storage networks Disk storage Tape automation Software Solutions

5 Understanding Your Business Risks How long can you afford to be without your IT systems? Recovey Time Objective (RTO) How much data can your company afford to lose? Recovery Point Objective (RPO) How much of your companies network must be restored in order to continue operations? Network Recovery Objective (NRO)??

6 Seven Tiers of Business Continuity Tier 0 - No offsite data Tier 1 - Pickup truck access method (PTAM) Tier 2 - PTAM + hot site Tier 3 - Electronic Vaulting Tier 4 - Active secondary site Tier 5 - Two-site two-phase commit Tier 6 - Zero data loss

7 Tier 0 Tier 0 - No offsite data no saved information (data, instructions, documents) no determination of requirements no backup hardware no contingency plan Typical recovery time unpredictable (includes never)

8 Tier 1 Tier 1 - Pickup truck access method (PTAM) selectively saved data determination of requirements optional backup hardware and backup facility available contingency plan available Typical recovery time usually more than a week Daily

9 Tier 2 Tier 2 - PTAM + hot site all requirements of tier 1 sufficient hardware and network to support the installation's critical requirements Typical recovery time usually more than one day Daily at Recovery Time

10 Tier 3 Tier 3 - Electronic Vaulting all requirements of tier 2 electronic vaulting of a some subset of information (e.g. transaction logs) Typical recovery time usually about one day Daily Daily at Recovery Time

11 Tier 4 Tier 4 - Active secondary site active management of recovery data by a processor at the recovery site bi-directional recovery physically separated Typical recovery time usually up to one day High Bandwidth connections Daily at Recovery Time

12 Tier 5 Tier 5 - Two-site two-phase commit requires tier 4 selected data in image status (updates to both sides within a single commit scope) requires partially or full dedicated hardware on secondary site capability to automatically transfer workload Typical recovery time less than 12 hours High Bandwidth connections

13 Tier 6 Tier 6 - Zero data loss immediate and automatic transfer to secondary site data is considered lost if ENTER has been accepted at the terminal, but the request has not been satisfied on the storage device Typical recovery time a few minutes advanced coupled High Bandwidth connections Data Sharing system

14 Where is your critical Service Level? Data Loss Weeks Tier 1 Tier 2 Days Tier 3 Hours Tier 4 Minutes Tier 6 Tier 5 Minutes Hours Days Weeks Service Loss

15 Key technologies Storage Networks - distance and connectivity Advanced disk copy functions Tape automation Software - more than just storage management Host 1 LAN Site 1... Host 12 up to 10km or 70km with additional fabric components Site 2 Host 12 LAN... Host 1 FC switch FC switch FC switch IFC switch Disk Storage Server Disk Storage Server

16 Storage Networks Application Server Direct Attached SCSI or FCS SCSI Protocol No sharing Limited connectivity Server centric storage Inefficient and expensive Application Servers Storage Area Network (SAN) FCS SCSI Protocol S A N Multiple heterogeneous servers sharing storage High performance dedicated storage network Extended distance - up to 100km High connectivity/availability - multiple paths Capacity and data sharing. Clients & Servers Network Attached Storage IP Network File Protocol (CIFS,NFS,HTTP,FTP,etc) NAS Clients sharing files Uses existing IP network and skills Very large distances - LAN, MAN, WAN Quick and easy to implement Capacity and file sharing

17 Storage Networks Clients & Servers IP Network NAS Gateway File Protocol (CIFS,NFS,HTTP,FTP,etc) NAS Gateway S A N SCSI Protocol Connecting SAN and NAS NAS 300G Combines advantages of sharing SAN storage with Client access over IP Block IO Application iscsi Attached IP Network SCSI Protocol Storage Clients sharing storage Uses existing IP network iscsi proposed standard NAS 200i and 300i Cisco SN5420 iscsi storage Router Application Servers Storage Virtualization SAN Virtual Storage Pool The next step... a Single storage pool Heterogeneous storage resources Copy functions across different storage vendors - unlimited distance Eliminate vendor specific storage limitations e.g. # and size of LUNs
