Clustered Data ONTAP 9 Administration

Clustered Data ONTAP 9 Administration

NetApp® ONTAP® 9 operating system, a major advance in enterprise data management software that combines new levels of simplicity and flexibility with powerful capabilities and efficiencies. With ONTAP 9 software, enterprises can quickly integrate the best of traditional and emerging technologies, incorporating flash, the cloud and software-defined architectures to build a Data Fabric foundation across on-premises and cloud resources.

Optimized for Flash 

ONTAP 9 software is optimized for flash with improved performance and capacity utilization. With this announcement, NetApp becomes the first all-flash array provider to offer customers 15TB solid state drives (SSDs), which are 50 percent larger than the largest hard-disk drives available today. NetApp also announced the FlashAdvantage 3-4-5 program, which includes the industry’s only guaranteed efficiency reduction of 4:1. This program makes it simple, cost effective, and low risk for customers to adopt flash.

New inline data compaction enables more data to fit in a smaller footprint and brings down the cost of flash beyond traditional compression and deduplication. This capability increases efficiency and makes NetApp all-flash systems extremely cost-effective compared to hard disk drive-based systems.

Simplicity, Flexibility and Security Across Flash, Disk and Cloud Deployments 
Users of ONTAP 9 software have three options to meet their needs. ONTAP 9 is targeted for general on-premises enterprise use, ONTAP Cloud (formerly NetApp Cloud ONTAP®) delivers enterprise-class data management in the cloud. The new ONTAP Select offers a software-only data management solution.

ONTAP 9 benefits include:

• Simplicity—Easy to set-up and manage, ONTAP 9 can be deployed and serving data for critical workloads in as few as 10 minutes. Also, with enhanced system monitoring, enterprises can use it to centrally manage performance, capacity and data protection across their IT environment.
• Flexibility—The ONTAP 9 software is the ideal platform for workload consolidation. The platform offers common data services across general purpose server hardware deployments as software defined storage (SDS) in addition to NetApp engineered systems, converged infrastructure, third-party arrays, next-to-the-cloud systems, and the cloud.
• Security—Customers can achieve up to 100 times greater security against drive failures and meet stringent data retention policies with new triple-parity RAID protection and expanded storage encryption and compliance features.

1. Download the ontap 9 cluster sim from netapp support site.

Deploy the OVA to the vmware work station and power on the simulator.

2. Select the advanced boot menu, option 4 to clear config and initialize the disk.

 3. Acknowledge it to do zero and create a new file system on disks.

4. Now it will create a new root Aggregate and creates root file system.

5. Next is cluster setup, first node use the command 'create'

6. Specify the cluster name and add the cluster base license key.

7. This process will create an cluster master and add the cluster services.

8. Now Set the cluster management port and ipaddress.

 9. Set the node management port and set the ip address.

10. Check with cluster show command.

11. Access via remote system using Putty with SSH

12. List the cluster RDB unit details.

13. List the disks.

14. Assign the disks now.

15. Access the cluster vis NetApp oncommand system manager.

16. New Ontap 9 System Manager's Dash Board.

19. Cluster performance list.

20. Network interface information.

21. Storage Details.

22. List the Aggregate details.

23. List the data protection snap shot polices and schedules.

24. Complete cluster configurations and update information.

25. Add capacity to an existing root aggregate aggr0.

26. Create a new aggregate.

27. Select a RAID Level. NetApp Ontap 9 Supports the following RAID levels.

RAID4 (Single disk Failure)

RAID DP (Dual Disk Failure)

RAID TEC (Triple Disk or Media Failure)

28. Create a new vserver(SVM).

29. Add the protocols to the SVM.

30. Create a new volume.

31. Create a new LIF with role Inter cluster communication.

Thank You.

Iscsi Target Configuration in Linux

Iscsi Target Configuration in Linux

iSCSI is a block level Protocol for sharing RAW Storage Devices over TCP/IP Networks, Sharing and accessing Storage over iSCSI, can be used with existing IP and Ethernet networks such as NICs, Switched, Routers etc. iSCSI target is a remote hard disk presented from an remote iSCSI server (or) target.

Features of iSCSI Target

§  Possible to run several iSCSI targets on a single machine.

§  A single machine making multiple iscsi target available on the iSCSI SAN

§  The target is the Storage and makes it available for initiator (Client) over the network

§  These Storage’s are Pooled together to make available to the network is iSCSI LUNs (Logical Unit Number).

§  iSCSI supports multiple connections within the same session

§  iSCSI initiator discover the targets in network then authenticating and login with LUNs, to get the remote storage locally.

1. Check whether the iscsi target has been installed or not. If it is not installed, install using YUM or RPM -ivh command.

2. Check the target daemon status and if it is not started, start the daemon.

3. Create the partition on new disk which supports LVM.

4. Now create a physical volume using the above partitions.

5. Create a volume group.

6. Create a Logical Volumes, and these logical volumes are act as LUN's.

7. Edit targets.conf file.

8. Reload the file configuration immediately.

9. From the host side, windows server check the disk drive information from the device manager.

10. Add the target portal information in iscsi initiator application.

11. Once the discovery portal added, then this will discover the assigned LUN's from the iscsi storage.

12. Login to the device.

13. Now the RAW disk is added to the windows host.

14. Now do the disk management like Disk partition, Format and Mount.

15. Same as you can discover the LUN from linux also. First check the iscsi initiator has been installed.

16. Add the target portal information.

17. Now you can able to see the new disks in linux server.
