Redundant Arrays of independent disks is a family of techniques that use multiple disks that are organized to provide high performance and/or reliability
RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDs) to protect data in the case of a drive failure.
This presentation gives an overview of physical storage technologies and the various ways of accessing storage on a computer or a server. Presented at School of Engineering and Applied Science, Ahmedabad University as a part of Software Engineering course.
Basic knowledge of Storage technology and complete understanding on DAS, NAS & SAN with advantages and disadvantages. A quick understanding on storage will help you make the best decision in terms of cost and need.

Raid the redundant array of independent disks technology overviewIT Tech
RAID (Redundant Array of Independent Disks) is a technology allowing a higher level of storage reliability and performance from disk-drive components via the technique of arranging them into arrays.
A RAID array is a configuration with multiple physical disks set up to use RAID architecture like RAID 0, RAID 1, RAID 5, etc. While the RAID array distributes data across multiple disks, it is considered as a single disk by the server operating system.

RAID, short for redundant array of independent (originally inexpensive) disks is a disk subsystem that stores your data across multiple disks to either increase the performance or provide fault tolerance to your system (some levels provide both).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. RAID Definition
RAID is a data storage
virtualization technology that
combines multiple physical
disk drive components into
one or more logical units for
the purposes of data
redundancy, performance
improvement, or both.
3. Why we use RAID?
RAID allows you to weather the failure of one or more drives without data
loss and, in many cases, without any downtime. RAID is also useful if you
are having disk IO issues, where applications are waiting on the disk to
perform tasks.
4. RAID
Advantages
Fault Tolerance.
Higher Data Security.
Increase the parity check for any possible system crash.
Reading and Writing of data done at simultaneously.
Improved Availability and performance.
Ensures data reliability.
5. RAID Limitations
▪ Write speed reduced compared to single drives.
▪ The storage capacity of the individual hard drives is
somewhat limited.
7. RAID 0
The main advantage of RAID 0 and disk striping is improved performance.
RAID 0 is an abbreviation of the
Redundant Array of Independent Disk
level 0. Raid 0 is also called striped
volume or stripe set or disk striping. Raid
0 is a standard level, which does not
consist of mirroring or parity, but only
consists of striping for handling the data.
8. RAID 1
Disk mirroring, also known as RAID 1, is
the replication of data to two or more
disks. Disk mirroring is a good choice
for applications that require high
performance and high availability, such
as transactional applications, email
and operating systems.
▪ Increased read performance.
▪ Provides redundancy and fault tolerance.
▪ Simple to configure and easy to use.
9. RAID 2
RAID 2 is another RAID standard level
configuration that provides very high
data transfer rates. In RAID 2, a
central controller synchronizes the
disks by making them spin at the same
angular orientation so that they all
reach the index simultaneously.
▪ Reliability.
▪ The ability to correct stored information.
10. RAID 3
RAID 3 is a RAID configuration that us e s a
parity disk to store the information
generated by a RAID controller instead of
striping it with the data. Because the parity
information is on a separate disk, RAID 3
does not perform well when tasked with
numerous small data requests.
▪ Good throughput when transferring large
amounts of data.
▪ High efficiency with sequential operations.
11. RAID 4
RAID 4 is a RAID configuration that uses a
dedicated parity disk and block-level
striping across multiple disks. Because
data is striped in RAID 4, the records can
be read from any disk. However, since all
the writes must go to the dedicated parity
disk, this causes a performance bottleneck
for all write operations.
▪ Fast read operations
▪ Low storage overhead.
▪ Simultaneous I/O requests.
12. RAID 5
RAID 5 is a redundant array of independent
disks configuration that uses disk striping
with parity. Because data and parity are
striped evenly across all of the disks, no single
disk is a bottleneck. Striping also allows users
to reconstruct data in case of a disk failure.
▪ High performance and capacity.
▪ Fast and reliable read speed.
▪ Tolerates single drive failure
13. RAID 6
RAID 6, also known as double- parity RAID
(redundant array of independent disks), is
one of several RAID schemes that work by
placing data on multiple disks and
allowing input/output (I/O) operations to
overlap in a balanced way, improving
performance. Not all types of R AID offer
redundancy, although RAID 6 does.
▪ High fault and drive-failure tolerance.
▪ Storage efficiency (when more than four drives are used).
▪ Fast read operations.
14. RAID 7
RAID 7 is a type of RAID level that includes a
real-time embedded operating system and
processor for enhanced data read/write or
I/O operations and data caching capabilities.
It is a propriety RAID level owned by Storage
Computer Corporation.
▪ Large Storage. To begin with, one of the most
obvious benefits is that a RAID has far more storage
capacity than a single drive.
▪ Fault Tolerance. Data backup in the array is created
automatically in most RAID levels.
15. CONCLUSION
RAID is an effective mass storage scheme for
improving speeds for streaming application
purposes and increasing redundancy to ensure
data safety. RAID 0 is best suited for
applications that require high-speed data
streaming.RAID is extremelyuseful if uptime
and availability are important to you or your
business. Backups will help insure you from a
catastrophicdata loss. But, restoring large
amounts of data, like when you experience a
drive failure,can take many hours to perform.
