Module 2: Storage Administrator Flashcards
(34 cards)
Setup and configure ONTAP as a new cluster
How do you complete the initial cluster set up according to the installation and set up instructions set up and configure on top software by using an TLI take a moment to review the steps in setting up and configuring on tap software on a new cluster cluster administration instructor lead training covers setting up and configuring on tap software, using CLA and app on top manager Also see the top nine documentation. The link to the documentation is provided in the resources page of this module. Alternatively, you could use a single modules for configuration management and automation of software.
1 - Cluster initialisation, set an admin password for the cluster set up cluster management and node management networks
2 - local tier set up; create local tiers form the available disks or SSDs in your nodes.
3 - Networking; setup the cluster interconnect, management network for cluster admin, and data network for data access.
4 - Protocol Configuration; depending on the licences enable the desired protocols on your cluster
5 - Storage provision; you can now provision storage. The options that you see depend on the licenses that are installed.
Unified storage; NAS, SAN and object storage
Operating systems and applications request data at the file level the block level or the object level provides access to data on a storage system. Data is accessible from the network that uses net app on tap services. The services include SMB, of which is CIFS is a dialect and NFS, in an environment and software controls the system. SAN provides block level access to data typically in units of 512 bites solutions can use iSCSI, FC, LEFCNNVME over fibre channel or NBME over FC protocols and environment. The host operating system controls the file system storage to provide object level access to data on object store server manages data as simple storage service or S3 objects, instead of file or block storage that’s provided on tap in sand servers. Data that consist of the object, data and data can be accessed directly through API or HTTP@ https. Ontap based storage system is a unified storage system that includes NAZ, SAN and object protocols.
ONTAP based storage architecture
It don’t have software discs are grooved in the rate groups and aggregate is a collection of visible disk space that contains one or more red groups. Each aggregate has a raid configuration and a set of assigned discs. The discs rate groups and aggregates make up the physical storage layer the top storage architecture uses a dynamic virtualisation engine in which data volumes are dynamically mapped to physical. Space a SVM or storage virtual machine. Also known as VM contains date volumes and lifts the date of store client data which is accessed through a lift inside a storage VM. You have flexible volumes or on tap, flex group, volumes, volumes, contain file, systems, lUNS, and VM spaces and buckets together. These elements make up the logical storage layer.
Data Volumes
On top software provides two types of volumes, flex ball, volumes and flex group volumes. Flexible volume is loosely coupled to a containing aggregate which the volume can share with other flexible volumes. Therefore one aggregate could be the shared source of all the storage that use by all the flexible volumes that the aggregate contains Because of flexible volume is managed separately from the aggregate you can create small flex volumes. You can also also increase or decrease the size of flex ball volumes. Flex group volumes are an ideal complement to the on scale out architecture flex group volumes, enable you to join multiple flexible volumes so that they appear to NA clients like a single name. space With flex group volumes, you can easily provision a massive single space in the constituent volumes in a flex group, collaborate to dynamically, balanced and space among themselves.
Flex Volume - are contained within an aggregate, and an aggregate can hold multiple flexVol volumes. Can contain NAS, SAN or both types of data (mixing not recommended). Can increase or decrease in size, as needed.
Flex group Volumes - Are shared pools of FlexVol volumes. Have component volumes that span multiple aggregates. Are within one namespace, and almost without limits.
Files, LUNs, NVMe namespaces and buckets
Date of the stored in a volume for an environment is stored as files or file shares files could be documents, database, files and logs, audio and video or application data on software manages the file system operations and clients access. The data data extort in a sand environment is stored in a logical container, which represents a scuzzy disc called one block And NASA or final data or treated differently files and Lowans should not be placed in the same flexible volume and NBME space is a quantity of envy ma’am that could be formatted into logical blocks name spaces are the equivalent of lines for FC and the protocols name spaces can be accessed using the NVEC protocol. Amazon S3 are kept in buckets. Amazon S3 objects are not nested as files inside directory that is inside other directories, the object store servers are associated with storage VM and the servers manage the objects, buckets and users. Review the actions that you can take on a volume you can change some options and the configuration of a flexible volume that affects the efficiency and quality of service or QOS to protect the data in the volume net on tap system manager formally on command system manager provides two levels of data protection, local and remote. The default remote protection policies could be either an asynchronous replication policy or a synchronous replication policy on tap software provide snapshot functionality, snap, mirror, functionality and snap mirror archival functionality to replicate and back up the date of blocks
Volumes properties
Actions: Create, edit, resize, delete, clone, move, restore
Volume options: Storage efficiency, storage Quality of service
Levels of data protection and tools: local, remote (asynchronous and sync), snapshot copies, mirror copies, archival
Managing Volumes
You could perform actions on volumes by using on tap system, manager or the CI volume commands. You can create a flexible volume for your data by using the volume dialogue box in system manager if the volume will be used for NAS protocols, you might need to create export and shares as necessary Environments. You can create created volume to create a flex group. Use the same procedure that you use to create a flexible volume in the ad, volume details page, scroll down until you reach the storage and optimisation section, selecting the distribute volume data across the cluster chat box causes system manager to create a group volume Rather than a flex volume can log into the CI to create the volume click the CI command button to review the commands that you use to create volume
Volume Move
FlexVol volumes could be moved from one aggregate or no to another within the same storage virtual machine or SVM a volume move does not disrupt access during the move. You can move volumes for capacity use such as more spaces needed. You can move volumes to change performance characteristics such as a controller with HDD one that uses solid drives SSD. You can also move volumes during service.
Application-aware data management
Application aware, data management enables you to describe the application that you want to deploy over on software in terms of the application rather than storage terms. The application can be configured and ready to serve data quickly with minimal input by using rest API application aware, data management feature incorporates relevant practices to optimum provision applications with placement of storage jobs, based on desired performance levels and available system resources Placement simplifies provision by eliminating questions, such as where is the capacity to match my application requirements or node or no have CPU head to take on additional work.
Balance placement (storage service levels)
Storage service levels help to ensure that limited or expensive cluster resources are dedicated to high priority. Workload effects are more noticeable, the larger cluster and the greater controller models and types in the cluster.

Manual selection of a local tier during volume provisioning, and Policy based storage management
Just if you could base selections on balanced placement logic system manager enables you to manually select the physical storage that you want to use when provisioning volumes. This includes the ability to specify aggregate during flex group creation, provision, storage, workload, volumes, and lines on your clusters and manage those workload based on performance levels functionality workload, quality of service or QOS policies, however applied by using unified manager, provision and manage workloads across all clusters unified manager instances monitoring for Brownfield environments, unified manager provides recommendations where the workloads are created without using unified manager performance service levels PSL’s. In addition, unified manager enables users to implement the recommended PSL to the workloads that do not have PS assigned.
KCQ1 - True or False: FlexVol volumes span multiple aggregates
False
Local and remote replication
The key principles of data protection include keeping data safe and making it available. If a failure occurs, depending on the requirement you could replicate data locally or remotely. You can copy data, remote, location, or the cloud. You can also plan for long-term data back up to take additionally, you should enc data to protect it, so that it remains hidden from accessible to authorise users.
RPO and RTP
The two key parameters that defined a business continuity and disaster recovery plan. RPO and RTO parameters are measured in units of time is the maximum acceptable amount of data could be a disaster occurs means that you can restore an application more than 30 minutes earlier than the time the outage occurred, the RTO is the maximum acceptable amount of time data is made available after a disaster. The RTO identifies how quickly you must recover your IT structure and services after a disaster and RTO of 10 minutes means that an application or a data should be back online within 1010 minutes after a failureidentifying the RPO and the RTO helping an organisation select the data protection solution that meets their requirements
Data protection levels
System manager provides a simplified workflow for creating and managing data protection relationships depending on your data protection and back up requirements. System manager provides two levels of data protection, local and revoke. A snapshot copy is a local only point in time. Image of data you can use system manager to create an advantage, the snapshot copy, policies and schedules. One of the remote protection policies is a synchronous replication. The asynchronous replication could be at the volume level known as snap software at the storage, BM or storage virtual machine also known as SVM level called storage, BM disaster recovery or SMDR. The other remote protection policies are synchronous replication and snap mirror business continuity. Metro Pluster software is a solution that combines a cluster with synchronous replication to deliver continuous availability and data loss at the lowest cost efficiently and securely. Protect your data in the cloud and cross. Clouds have offers cloud solutions that are designed to help you to simplify protection of your data with rabbit recoveryavailable on tap cloud data protection solutions include cloud volumes on tab, snap, mirror, cloud, app, cloud, backup service app, cloud, sync service in the data protection course
Snapmirror replication
You use tap system manager to protect volumes as part of creation, protect an existing volume and create protection relationships from the destination. Snap mirror uses a snap mirror policy for the policy type you must select asynchronous mirror in the policy. You can also select whether to transfer all source snapshot copies from the source volume to the destination volume there are variance of the policies that are available for snap mirror. These variants that are listed on the screen are available through CL when you create a mirror relationship, you must configure a schedule the schedule defines when the updates occur. You can assign default schedules or create custom schedules. When you use on system manager to configure your snap mirror you use the option in the drawdown. The policy is equivalent to the mirror and policy, you can set up the mirror all snapshot policy, select source storage configuration option and exclude network interface option.

Products for storage administrators
Learn how to set up and configure active, IQ unified manager, cloud, insights and snap as a storage administrator cell will find these products useful set up and configure active IQ unified manager
Active IQ unified manager
System three instances of unified manager constantly manager, the data centres and fourth instance of unified manager includes all the data centres along with all of their resources uses this for instance, mostly for reporting and performance monitoring purposes. You can deploy unified on a line server on a window server or as a virtual appliance on a VM warehouse The, unified manager, server infrastructure consist of a data collection unit, a database and an application server. It provides infrastructure services such as discovery monitoringcontrol auditing and logging installation and configuration of unified can be broadly classified in three steps. Take a moment to review the steps. See the unified manager documentation for more details. The lake is provided in the resources page of this module.
Installation and configuration (unified manager)
Install: (ensure pre request set for hardware and software), collect required conf info, install
Configure initial settings: launch the web UI, performance initial setup. Enter maintenance user email, configure auto support.
Add clusters
Configure admin settings: set up users, notifications, smtp, edit global health thresholds, configure performance thresholds.
Configure and setup quotas. Configure and setup alert for events
Unified manager: add clusters
You can add a cluster to active IQ unified manager so that you can monitor. The cluster monitoring. Includes the ability to obtain cluster information such as the health capacity performance and configuration of the cluster so that you can find and resolve any issues that might occur cell add clusters to the respective instance of active IQ unified manager after all the objects were a new cluster are discovered about 15 minutes. Unified manager starts to gather historical performance data for the previous 15 days. These statistics are collected by using the data continuity collection functionality, this feature provided over two weeks of performance information for a cluster immediately After the continuity collection cycle is completed by at least five minutes
Unified manager: SETUP notifications, and setup users
You can you unified manager to send alert notifications when an event is generated or when an event is assigned to a user you can configure the SMTP server that is used to send the alert and you can set notification mechanisms example, alert notifications can be sent as an email messages or SNMP traps.
In organisation, it is practically not feasible to constantly monitor unified manager for any risks in advance. It is required that you add users so they can be alerted in any events. You can add local users or database users by using the users page. You can also add remote users or groups that belong to an authentication server, you can assign These users and based on the privileges of the roles users can manage the storage jobs and data with unified manager or view. Data database group is a collection of storage group in unified manager to easily manages set of storage jobs rule can configure level health threshold, capacity, quotes growth, and for example, configure, volume threshold, group, action, simultaneously, change the volume threshold of all volumes in a group, an annotation rule is a criterion that you define to annotate clusters or SVM. Annotation pair can be dynamically associated with storage jobs by using annotation rules. When you associate storage jobs with predefined annotations, you can filter and view the events that are related to them, you can apply annotations to clusters volumes, NVM Provision storage workload, volumes and lines manage those workload based on a performance service levels. This functionality is like creating workload and system manager attention quality of service or QOS policies. However when applied by using unified manager, you can provision and workloads across all clusters that your unified manager instances monitoring for Brownfield environments unified manager provides recommendations where the workloads are created without using unified manager, performance service levels, PSL’s And attention unified manager enables users to implement the recommended PSL to the workload that do not have PSL assigned
