2 2 Storage Opslag DAS Direct Attached Storage NAS Network Attached Storage SAN Storage Area Network

3 3 Wat is een SAN ? 1)Gecentraliseerde opslag op basis van een extern schijvencabinet voor verschillende typen servers « alles in één doos » gecentraliseerd beheer hoge schaalbaarheid door veel schijfruimte hogere hardware redundantie en databeveiligingsfuncties : RAID, spare disks 2) Speciaal storage netwerk Fibre-Channel grote afstand (optische kabels ) hoge bandbreedte (4Gb) iSCSI ethernet direct toepasbaar en flexibel lage TCO en infrastructuurkosten

4 4 Voordelen van gecentraliseerde opslag Flexibel en eenvoudig toewijzen van capaciteit Gemiddelde benutting in een DAS-omgeving is < 50% (SAN = 85%) Schijf en tape in hetzelfde opslag netwerk (50-75% minder tape drives) Minder LAN-verkeer Gecentraliseerd beheer Beheer met minder mensen (efficiency stijgt met factor 10) Opslag, switches en tape toevoegen zonder applicaties stop te zetten Zo veel redundantie als gewenst

5 5 iSCSI Storage iSCSI staat voor Internet SCSI (Small Computer System Interface). Dit is een op het Internet Protocol (IP) gebaseerde standaard voor IP netwerken. Deze technologie is een versmelting van twee technieken die zich in de industrie bewezen hebben. Het gaat om de technologie die ontwikkeld is voor communicatie (ip netwerken) en de technologie bedoeld voor dataopslag, SCSI opslag. Door deze te combineren werd het mogelijk zowel de data als de dataopslagcommando's over ip-netwerken te versturen. Een netwerk protocol voor storage netwerken Gebruikt de standaard ethernet tcp/ip netwerktechnologie eb hardware

6 6 Fibre Channel SAN Fibre Channels work on a single popular storage networking protocol that offer compatibility to all common storage and database servers. Fibre Channels use the FCP protocol ( Fibre Channel Protocol) which is simply a serial bus SCSI protocol. This FCP (Fiber Channel protocol) works really well in networks with a high bandwidth requirement. Fibre Channel is een protocol dat voornamelijk wordt gebruik om data binnen storage netwerken te transporteren. Vaak wordt Fibre Channel geassocieerd met alleen glasverbindingen, maar het protocol kan zowel over glas als koperverbindingen worden gebruikt.

7 7 iSCSI voordelen door Eenvoud Geen noodzaak meer om te investeren in FC technologie of FC kennis Ethernet is bekende technologie Ethernet heeft een lagere TCO en infrastructuur Geen noodzaak meer om te investeren in FC technolog of FC kosten Geen FC HBAs meer nodig, optionele iSCSI ethernet kaarten voor hogere prestaties

11 11 Typical Storage Array Architecture Monolithic Array Not scalable Controller head becomes bottleneck Scales capacity only Single point of failure Forklift upgrades

22 22 Network Storage Server (NSS) Intelligent Storage Virtualization True heterogeneous intelligent storage virtualization Application-aware data protection WAN optimized disaster recovery services protect operations and save on WAN costs Increased storage efficiency through Thin Provisioning of resources Your Storage, Your Infrastructure, Your Solution

23 23 TOTALLY Open Storage Virtualization Platform Data Physical Existing SAN volumes via Storage Service Enabler Virtualized SAN volumes Thin provisioned SAN volumes LinuxSolarisHP-UXAIXNetware ExchangeOracleVMwareNotesSQL SAP DB2 Windows Any application Any operating system Virtual Any storage protocol Any disk array

24 24 Control storage management cost and complexity Consolidate heterogeneous storage management through virtualization Minimize storage costs with thin provisioning Centralized management of client systems simplifies operations

25 25 The Solution Starts with Consolidation Enhanced storage utilization Consolidated storage management Opens the door for a host of solutions and innovations Application Servers File Servers Backup Severs Critical Applications SAN

26 26 How storage virtualization works Quickly create virtual volumes from across or within any physical disk resources - Simple wizard interface - Physical LUN and virtual devices up to 16TB -Expand volumes as needed Securely assign volumes to servers through NSS interface Virtual disks Physical disks

27 27 Storage abstraction layer Move the storage intelligence and security into the SAN fabric NSS creates a storage abstraction layer Storage services no longer dependent on vendor-exclusive disk functionality Consolidates services and operations Hosts Fabric Storage abstraction layer Disk

28 28 Thin Provisioning: Better Storage Utilization Create a virtual volume to match size of data provisioning request Allocate a smaller amount of actual physical disk space Additional physical space allocated automatically as needed Reduces wasteful over provisioning of storage Saves disk space and power consumption Data Virtual Thin provisioned SAN volume Physical 200 GB 800 GB “800 GB”

29 29 Minimize downtime Highly available systems ensure continuous operation Cross-array mirroring for ultimate data protection Seamless, zero-downtime data migration

30 30 NSS high availability deployment model NSS appliances deployed in failover pairs Each NSS server supports its own set of client servers during normal operations If one devices fails, the second device takes over servicing clients Shared Storage Failover SAN

31 31 Data mirroring, zero downtime migration Any-to-any storage array synchronous data mirroring Ultimate data protection across arrays Seamless data migration across storage devices. Create mirror Switch primary/mirror status without any break in application processing Remove mirror (old array) PrimaryMirror PrimaryMirror Writes acknowledged from both arrays to ensure integrity

32 32 Ensure comprehensive data protection Application-aware snapshots provide rapid data recovery WAN optimized data replication for disaster recovery and failback Host-free, accelerated backup eliminates all backup windows

33 33 Application aware snapshots Up to 256 snapshots per volume Instant recovery to any captured point in time Fully mountable as read/write volumes Application agents and consistency groups for 100% transactional integrity MS Exchange Oracle VMware DB2 Informix SAP MS SQL Sybase Notes/Domino Progress Pervasive SQL 8:009:0010:0011:00 1:005:009:00 1:001:302:002:30 Each volume has its own snapshot schedule

34 34 WAN Optimized Disaster Recovery Full replicas Copy to tape DR Site … … Snapshots WAN optimized out of the box Includes WAN data encryption, compression and QoS Easily configured any-to-any remote replication Continuous or periodic modes

35 35 WAN Optimized Data Replication Applications and file systems write far more data to disk than actual changes NSS scans the changes at a 512 byte level and replicates only the changed data - Avoids constant re- sending of duplicate data 512 byte = empty disk sector = data written by application or file system = sector with actual data change A typical 8k write of data. Many systems send all 8k or more. CDP sends only the truly changed sectors. 512 byte Disk sectors
