6. How to measure the cache memory read performance?
Read performance is measured in terms of the read hit ratio, or the hit rate, usually
expressed as a percentage. This ratio is the number of read hits with respect to the total
number of read requests.A higher read hit ratio improves the read performance.
7. What is cache mirroring?
Each write to cache is held in two different memory locations on two independent
memory cards. In the event of a cache failure, the write data will still be safe in the
mirrored location and can be committed to the disk.
8. What is cache vaulting?
Cache is exposed to the risk of uncommitted data loss due to power failure.This problem
can be addressed in various ways:
power ing the memory with a battery until AC power is restored or using battery power to
write the cache content to the disk.
9. What is Cache coherency?
Cache coherency means that data in two different cache locations must be identical at all
times.
10. How cache memory to achieve flushing process?
Flushing is the process of committing data from cache to the disk. On the basis of the
I/O access rate and pattern, high and low levels called watermarks are set in cache to
manage the flushing process.

the tracks are packed on a platter.
17. Uses of zoned bit recording in disk drives
In computer storage, zone bit recording (ZBR) is a method used by disk drives to
optimise the tracks for increased data capacity. It does this by placing more sectors per
zone on outer tracks than on inner tracks.
18. Define RAID.

A subset of disks within a RAID array can be grouped to form logical associations called
logical arrays, also known as a RAID set or a RAID group .
20. Define RAID strip.
A RAID set is a group of disks. Within each disk, a predefined number of contiguously
addressable disk blocks.
21. What is RAID mirroring?
Mirroring is a technique whereby data is stored on two different HDDs, yielding two
copies of data. In the event of one HDD failure, the data is intact on the surviving HDD
and the controller continues to service the host’s data requests from the surviving disk of
a mirrored pair.

Virtualization simplifies resource management by pooling and sharing resources for
maximum utilization and makes them appear as logical resources with enhanced
capabilities.
3. State the connectivity of iSCSI protocol.
▪ Native iSCSI connectivity - Native topologies do not have any FC components; they
Perform all communication over IP. The initiators may be either directly attached to
targets or connected using standard IP routers and switches.

13
Bridged iSCSI connectivity - Bridged topologies enable the co-existence of FC with IP
by providing iSCSI-to-FC bridging functionality. For example, the initiators can exist in
an IP environment while the storage remains in an FC SAN.
4. What is zoning?
Zoning allows for inner segmentation of the switched fabric. Zoning can be used to
instigate a barrier between different environments.
Only the members of the same zone can communicate within that zone; all other attempts
from outside are rejected.
Zoning can be implemented in the following ways:
 Hardware zoning
 Software zoning
5. Define switch aggregation?
An aggregation switch is a networking device that allows multiple network connections
to be bundled together into a single link. This enables increased bandwidth and better
network performance.
6. What is meant by file-based storage system?

Unified storage architecture enables the creation of a common storage pool that
can be shared across a diverse set of applications with a common set of management
processes.
12. What is the use of FC-SAN?
Fibre Channel SAN (FC SAN) is also referred as SAN. It uses Fibre Channel
(FC) protocol for communication. FC protocol (FCP) is used to transport data,
commands, and status information between the compute-systems and the storage systems.
It is also used to transfer data between the storage systems.
13. How to achieve data transmission in FC-SAN?

17. Difference between Multimode fiber (MMF) cable and Single-mode fiber (SMF).
 Multimode fiber (MMF) cable carries multiple beams of light projected at different
angles simultaneously onto the core of the cable.
 In an MMF transmission, multiple light beams travelling inside the cable tend to
disperse and collide. This collision weakens the signal strength after it travels a certain
distance a process known as modal dispersion.
 Due to modal dispersion, an MMF cable is typically used for short distances,
commonly within a data center.
 Single-mode fiber (SMF) carries a single ray of light projected at the center of the
core. The small core and the single light wave help to limit modal dispersion.
 Single-mode Provides minimum signal attenuation over maximum distance (up to 10
km).
 A single mode cable is used for long-distance cable runs, and the distance usually
depends on the power of the laser at the transmitter and the sensitivity of the receiver.
18. Define VSAN Trunking link.
VSAN trunking allows network traffic from multiple VSANs to traverse a single ISL. It
supports a single ISL to permit traffic from multiple VSANs along the same path. The ISL
through which multiple VSAN traffic travels is called a trunk link.
19. What is VSAN Tagging?
VSAN tagging is the process of adding or removing a marker or tag to the FC frames
that contains VSAN-specific information. Associated with VSAN trunking, it helps
isolate FC frames from multiple VSANs that travel through and share a trunk link.

16. Define Big bang migrations.
Big bang migrations transfer all associated data within a set time window. The
advantages of creating a migration strategy around this method include lower cost, a
quicker move and less complexity. The downside, however, is that big bang migrations
require the system to be offline for the entire migration. There's also a risk of losing data
if it isn't properly backed up to another location ahead of time.
17. Define Trickle migrations.
Trickle migrations complete a data migration within phases. During the migration, both
old and new systems run at the same time, so there's no downtime, which means there's
less risk of losing data. However, trickle migrations are more complicated and need more
planning and time to implement properly.
18. What are the phases available in data migration process?
o Discovery. This should include considerations such as data sources, destinations,
security, cost and which migration strategy to use.
o Resource assessment. Identify who will be taking part in the migration.
o Data inspection. Examine the data being migrated for data quality, anomalies or
duplications.Data should also be backed up.
o Design. Data is organized and mapped out for where it's being moved to.
o Software tools. Any software that will help in the transition is purchased or
created.
o Migration. The migration process is initiated.
o Cleanup. Old or legacy systems are shut down and decommissioned.
19. What are the categories in data movers?
o Host-based software is best for application-specific migrations, such as
platform upgrades,database replication and file copying.
o Array-based-based software is primarily used to migrate data between similar
systems.
o Network appliances migrate volumes, files or blocks of data depending on
their configuration.
20. Difference between Data migration and data conversion.
Data migration is the process of transferring data between data storage systems or
formats.
Data conversion is the process of changing data from one format to another. If a legacy
system and a new system have identical fields, an organization could just do a data

21
migration; however, the data from the legacy system is generally different and needs to
be modified before migrating. Data conversion is often a step in the data migration
process.
