Storage and Data Management

Big Data Dimensions

• A limitation is that it isn't the most widely used topology supporting a maximum of 127 devices.

Disk Drive Performance Statements

• Disk drive with a low latency performs better than a disk drive with a high latency

Data Migration with SmartTier

• If no data migration plan is set, with SmartTier enabled, there will be no data movement at all between tiers

Clustered NAS Architecture Element

• Global Namespace allows file system consolidation, needs no separate management

Cloud Service Model

• Infrastructure As A Service (IaaS) provides storage, networks, servers, and virtualization.

Correct RAID 2.0+ statement

• Chunks of a file will never be on the same physical disk

IP SAN Scenario

• IP SAN can be used for networking deployment if the services don't need high access speed.

QoS Principle

• I/O Latency Burst is not a working principle of QoS.

App Program Interface (API)

• API (Application Program Interface) is a set of routines, protocols, and tools for building software applications.

Volume Statement

• Multiple volume groups can be created from a physical volume, not a logical volume.

ICT Infrastructure OS Types

• The servers can run different OS like Windows, Linux or AIX

Hard Disk Size Divisions

• Sector, Cylinder and Track are divisions of a hard disk

HyperReplication for HUAWEI OceanStor V3

• FC links can be used between data centers
• iSCSI links are not supported

Disk Domain Rebuild Time

• With 40 disks it rebuilds faster than with 20

Storage Area Networks (SAN)

• SAN is a storage architecture that connects storage devices and application servers through a network.

Requirements of Parity in RAID Configuration

• Requires data reliability and improvements
• Parity data should be stored on different disks

Intermittent Network Connection

• Most likely caused by crosstalk and interference

Data Loss Backup Strategies and RTO

• Data loss still occurs when tape is used as a restore method
• High RTO is expected when using tape

Purpose of Context for Data

• Gives meaning to data collected
• Without context, data is meaningless

OceanStor Expansion

• Adding additional controllers to an existing HUAWEI OceanStor system requires a Smart I/O card.

Classification Storage Information

• Data access frequency classifies online, nearline and offline storage

Mounting via Linux Command

• mount /dev/sdb5 /mnt/sdb5 correctly mounts in Linux systems

Backup Frequency

• Retention period determines frequency of backups
• Incremental backups won't take a long time to complete

RAID 2.0+ and traditional RAID

• Offers better protection against data loss and performs much better than traditional RAID
• To rebuild, a protected failed drive takes a lot of time because all drives are involved with the spare disk

Access to DeviceManager

• The maintenance network port is used by the DeviceManager for daily management
