3. Agenda Storage Trends DAS (Direct Attached Storage) NAS (Network Attached Storage) SAN (Storage Area Network) 1 Benefits of NetWare ® as a storage platform 2 iSCSI the solution for testing and training Clustering 3 Configuring iSCSI storage – Demo 4 Installing Novell Cluster Services™ (NCS) – Demo 5 Creating and migrating Cluster resources - Demo 6 Novell ATT courses 7

4. Companies are detaching storage from servers to manage escalating storage needs This means deploying NAS and SAN technologies Storage area networks and network attached storage require 75% less personnel to maintain than traditional direct attached storage Storage Today—DAS, NAS, and SAN Direct Attached Storage (DAS) Windows NT/2KLinux/UnixNetware Network Attached Storage (NAS) Windows NT/2KLinux/UnixNetware Storage Area Network (SAN) Netware Windows NT/2K Linux/Unix Storage FC Switch NAS

5. The Problem with DAS Direct Attached Storage (DAS) Data is bound to the server hosting the disk Expanding the storage may mean purchasing and managing another server Storage is often provisioned badly In heterogeneous environments, management is complicated Windows NT/2KLinux/UnixNetware

6. NAS Issues Network Attached Storage (NAS) Each appliance represents a larger island of storage Data is bound to the NAS device hosting the disk and cannot be accessed if the system hosting the drive fails Storage is labor- intensive and thus expensive Windows NT/2KLinux/UnixNetware NAS

7. Benefits of SANs Storage Area Network (SAN) Server Consolidation Storage Consolidation Storage Flexibility and Management LAN Free backup and archive Modern data protection (change from traditional tape backup to snap-shot, archive, geographically separate mirrored storage) Windows NT/2K Linux/Unix Netware SAN Switch

8. Storage Area Networks (SANs) Result of applying core networking principles to storage Retains the flexible topologies, scalability and dynamic behavior of networks Servers are attached to 2 distinct networks Back-end – servers connect to storage devices Servers become clients of storage devices Front-end – Unchanged LAN Clients see the SAN as DAS (Direct Attached Storage)

9. Key Benefits of NetWare 6 as a Storage Platform Totally scalable, high-performing, feature-rich, distributed SAN file system: Novell Storage Services™ (NSS) Up to 8 TB volumes (no limit to the number of volumes) Journaling Compression Open file backup support Mirroring and striping Disk quotas Volume pooling and junctions High integrity volumes-flush cache on close Shared disk support for better SAN integration XML-based management infrastructure

10. Novell clients (NCP) Windows clients (CIFS) Unix clients (NFS) Macintosh clients (AFP) Web and Internet clients (HTTP, HTTPS, FTP, and WebDAV) Key Benefits of NetWare 6 as a Storage Platform (cont.) Native support for all major client access methods

11. Up to 32 servers in an all-active cluster Fan-out failover for load balancing on failover Transparent failover Enhanced cluster resource management Integrated with eDirectory™ Intelligent cluster volume operations Built in cluster volume manager allows for dynamic volume changes in the SAN without rebooting any servers Key Benefits of NetWare 6 as a Storage Platform (cont.) Highly-scalable, load-balancing, directory-enabled clustering environment

12. General purpose backup for all SAN data No more zoning off portions of the SAN for specific operating systems No need to learn and deploy multiple clustering solutions No more mis- provisioned disks on servers or NAS devices Novell Cluster Services Windows NT/2K App Server Linux/Unix App Servers Windows, Mac, Unix, and Novell clients NetWare 6 Storage Area Network (SAN) Netware6 Cluster

13. So, get a SAN!

14. NTS problem We can’t teach a clustering course on enterprise equipment because the hardware is too expensive and too heavy.

15. iSCSI to the rescue Any computer that meets NW6 hardware requirements can become a SAN storage device Use existing servers as your shared storage. iSCSI can run as an additional service. iSCSI on Gigabit Ethernet Hardware is a fraction of the cost of a full Fibre Channel SAN solution. iSCSI is slower but even cheaper on 100 Mb.

17. iSCSI Software Stack Target (storage server) appears as local storage device to Initiator(s) Initiator(s) are storage clients that connect to the target server Target Initiators

18. iSCSI Software Stack iSCSI Target: iscsinit.nlmInitiator controller iscsiham.hamNetWare HAM driver ion.ncf,Batch file to load initiator ioff.ncfBatch file to unload initiator iSCSI Initiator: iscsitar.nlmTarget controller Ton.ncfBatch file to load target Toff,ncfBatch file to unload target iscsilib.nlmiSCSI common functions iscsinrm.nlmNovell Remote Manager plugin ioctl.nlminterface functions Iscsixml.nlmXML interface module red_flag.gif Novell Remote Manager icons green_flag.gif yellow_flag.gif iSCSI common files:

19. iSCSI Target Create a single iSCSI partition on target machine. Load iscsi target (ton.ncf) on the target machine. It will display the GUID of the iSCSI partition.

20. iSCSI initiator(s) Load SCSIHD.CDM if not already loaded. Run ION.NCF (loads files) Use NoRM or command line to connect to Target (ip address) In NoRM, select Storage Services -> iSCSI Services. Click on the New Session button and enter the ip address of your target. Or at the command line, enter: iscsinit connect View the available disk: In NoRM: Manage Server->Volumes->Disk Partitions Command line: list devices ConsoleOne: Properties of server->media tab->devices

21. Initialize the iscsi disk, make it sharable & create an NSS partition using ConsoleOne ® or NoRM. You don’t have to use all the space available. Create a Pool on your newly created partition. Create a volume(s) in your pool. If users will need file access Cluster Enable the Volume Chose access protocols - NCP, CIFS, AFP Mount the volume iSCSI initiator(s) – (Continued)
