Sharing of files between DAS solutions is possible via the network.

Consists of a server/host with its locally connected disk drives.

More scaleable in capacity than a SAN solution.

Backups are centrally made on a special backup server.

The primary controller processes the I/O requests from application servers and the secondary controller is in the idle state.

The active-active mode achieves load balancing, full utilization of resources, and system performance improvement.

Two controllers process the I/O requests from application servers concurrently.

If a controller becomes faulty, the other takes over the work of the faulty controller without disrupting ongoing services.

Implement a NAS storage with the CIFS file system.

Implement an IP SAN network with Ethernet switches.

Implement a FC SAN with FC switches and SFP.

Implement a NAS storage with the NFS file system.

Statement 1 is true; Statement 2 is false.

Statement 1 and 2 are true.

Statement 1 and 2 are false.

Statement 1 is false; Statement 2 is true.

To be able to swap out the disks when the temperature is too hot.

To swap out the hard disks after proper shutdown of storage system.

Maintain the temperature of the disks to prevent overheating.

To swap out the hard disks without turning off the storage system.

FALSE

TRUE

ICT is slowly being replaced by other new technologies such as IT and CT.

The initial phases of ICT focuses on office automation but slowly changed towards changing business flows.

ICT trend is changing slowly with little significant changes.

ICT has become the core in the production systems in the recent years.

Both the CIFS as well as the NFS protocol requires file format conversion.

One disadvantage of CIFS is that Windows clients must be equipped with dedicated software.

NFS is a stateless protocol while CIFS is a stateful protocol. NFS can be automatically recovered from a fault while CIFS cannot.

CIFS is a network-based sharing protocol. It has high demands on network transmission reliability, so it usually uses TCP/IP.

SmartTier supports a High Performance, a Performance, a High Capacity and a Capacity Tier.

Only when a snapshot is activated will the system record all changes to the original LUN.

To write data to the secondary LUN of a clone pair, the pair must be split.

A snapshot needs to be removed from the LUN group to be fully unmapped.

Average access time

Sector size

Capacity

Rotational speed

When it has been stored in the right file format.

When it has been stored in a digital form.

When the company understands the data and learns from it.

All of the above.

SAN and NAS convergence

SSD and HDD convergence

No need for heterogeneous convergence anymore

Primary and Backup convergence
