The document provides an overview of storage technology options including network attached storage (NAS), storage area networks (SANs), and discusses specific NAS and SAN products. It highlights the key features of an iSCSI SAN brick platform including software for snapshots, replication, and continuous data protection. Appliance strategies and partnerships are also summarized.

3. Use Cases Drive Storage Requirements Applications Operating Environments : Storage Infrastructure Applications have varying needs for storage Operating Environments require storage infrastructure which can deliver a multitude of storage services SQL, Oracle, Web 2.0, CRM, ERP, Exchange, SharePoint, Audio, Video, PDF, Docs, etc. Windows, Linux, Solaris, VMware, Virtual Iron, Citrix/Xen Block Level Access, File Sharing, Data Protection, Data De-Duplication Disaster Recovery

4. General Storage Technology THINGS TO CONSIDER THE GOOD No Network or External Arrays Needed Fast Through-Put Difficult To Maintain Does Not Balance Loads Small and Predictable Storage Flat File Storage Simple To Configure And Maintain Primarily targeted at storing files, not blocks Data Back Up Simple Extra Storage Moving Large Blocks Of Data, Scaleable, Reliable, Ease Of Management Price Point Bandwidth Intensive Mission Critical Data WHO SHOULD USE? DAS NAS SAN WHERE IS THE BEST FIT Local Operating System Flat File, Simple data changes I/Op Intensive, quick block changes, Databases

36. SnapShots & Replication

38. Snapshots – Recovering Data Snapshot created at 10:00 AM This report Is due This report Is due File is recovered at 10:12 AM The file is recovered from the snapshot image created at 10:00 AM and in that time the user made some changes. However, the majority of the report is the same. File is accidentally deleted at 10:10 AM This report Is due today

43. FalconStor ‘Disk Safe Agents’ Real time, continuous client / server disk protection

44. Disk Safe Agents for Continuous Data Protection Disk Safe agent software resides on client and server disks the customer wants to protect. As a protected disk is written to, the agent simultaneously sends the written data to the iSCSI Brick Should a protected disk fail completely, the disk can be replaced, the system PXE booted, and the entire disk recovered. PROTECTED!!! PROTECTED!!! PROTECTED!!! PROTECTED!!!
