Storage Systems

Overview

Introduction:History: computing, networking, storage - Need for storage networking - SAN, NAS, SAN/NAS Convergence - Distributed Storage Systems - Mainframe/proprietary vs. open storage - Storage Industry Organizations and Major Vendors Market - Storage networking strategy (SAN/NAS or Distr storage) - Impact of Regulations: existing and new;Technology:Storage components - Data organization: File vs. Block, Object; Data store; Searchable models - Storage Devices (including fixed content storage devices) - File Systems - Volume Managers - RAID systems - Caches, Prefetching;Network components:Connectivity: switches, directors, highly available systems - Fibre Channel - 1GE/10GE, Metro-ethernet - Aggregation - Infiniband;Error Management:Disk Error Mgmt - RAID Error Mgmt - Distr Systems Error Mgmt;Highly available and Disaster-tolerant designs:Ordered writes, Soft updates and Transactions - 2 phase, 3 phase, Paxos commit protocols - Impossibility Results from Distributed Systems - Choose 2 of 3: Availability, Consistency and Partition Tolerance;Layering and Interfaces in Storage Protocols:eg. SCSI 1/2/3SNIA model;SAN Components:Fibre Channel - IP-based Storage (iSCSI, FCIP, etc.) - Examples - NAS - NFS - CIFS - DAFS;Large Storage Systems:Google FS/BigTable - Cloud/Web-based systems (Amazon S3) - FS+DB convergence - Programming models: Hadoop;Archival Systems:Content addressable storage - Backup: serverless, LAN free, LAN Replication issues - Storage Security - Storage Management - Device Management - NAS Management - Virtualization - Virtualization solutions - SAN Management - Storage Provisioning - Storage Migration - SRM
