Module 2 Flashcards
Block Storage
Block storagebreaks up data intoblocksand then stores thoseblocksas separate pieces, each with a unique identifier.
File Storage
is a hierarchical storage methodology used to organize and store data on a computer hard drive or on network attached storage (NAS) device. In file storage, data is stored in files, the files are organized in folders, and the folders are organized under a hierarchy of directories and subdirectories. To locate a file, all thecomputer system needs is the path —from directory to subdirectory, to folder, to file.
Object Storage
Object storage, often referred to as object-based storage, is a data storage architecture for handling large amounts of unstructured data. This is data that does not conform toor cannot be organized easily intoa traditional relational database with rows and columns.
Software Defined Storage (SDS)
Is a storage design that separates storage software from hardware. It typically includes a form of storage virtualization to separate the storage hardware from the software that manages it.SDS provides the flexible storage foundation users need for hybrid cloud, digital transformation and more.
Backup
Backupis the process of making an extra copy (or multiple copies) of data. Usersback up data to protect it. A user might need to restore backup data if they encounter an accidental deletion, database corruption, or problem with a software upgrade.
Disaster recovery
refers to the plan and processes for quickly reestablishing access to applications, data, and IT resources after an outage. That plan might involve switching over to a redundant set of servers and storage systems until a primarydata center is functional again.
Backup and restore
Refers to technologies and practices for making periodic copies of data and applications to a separate, secondary device and then using those copies to recover the data and applications, n the event the original data and applications are lost or damaged due to a power outage, cyberattack, human error, disaster, or some other unplanned event.
Types of backup
Tape Drive,Hard disk (HDDs) and solid state (SDDs),Back up server,Cloud backup
Disaster Recovery on Power System VS
The Power Systems Virtual Server instance restarts the virtual servers on a different host system if a hardware failure occurs. This process provides basic High Availability (HA) capabilities for the Power Systems Virtual Server service.
Zerto
This service provides replication and disaster recovery capabilities, which can be integrated into the deployment offerings to protect and recover data in a VMware virtual environment on IBM Cloud.
Veeam
Veeamprovides recovery points and time objectives for userapplications and data. The recovery points and time objectives can be provided in less than 15 minutes after configuration is completed.
IBM Spectrum Protect Plus
s a service that provides an efficient and scalable solution for data protection, data reuse, and data recovery for virtual environments. Users can implement the service as a stand-alone solution, or it can be integrated with the IBM Spectrum Protect environment to offload copies for long-term storage and data governance.
MIMIX
MIMIX Availability delivers robust high availability and disaster recovery protection for IBM i that keeps a customer’s business running, no matter what. Real-time replication to a secondary server that is continuously audited for synchronization gives them confidences that their business operations can switch to a waiting standby server at a moment’s notice.
Endurance tiers and performance tiers are considered provisioning options for which of the following?
