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.
Virtualization refers to the creation of a virtual resource such as a server, desktop, operating system, file, storage or network.
The main goal of virtualization is to manage workloads by radically transforming traditional computing to make it more scalable.
The server administrator uses a software application to divide one physical server into multiple isolated virtual environments.

TECHNICAL BRIEF▶ NDMP Backups with Backup Exec 2014Symantec
The Symantec Backup and Recovery product family offers market-leading backup and disaster recovery solutions for critical customer IT resources. This includes Symantec Backup Exec and Symantec NetBackup, leading solutions for enterprise, mid-market and small business customers.
The network data management protocol (NDMP) is an industry-standard programming interface that provides best practice backup and recovery for NAS systems. An NDMP-approach enables a backup server to communicate directly with a NAS filer and to transmit data to the specified backup storage device. NDMP eliminates the need for backup vendors to write device-specific code for NAS devices to facilitate backup.

A Distributed File System(DFS) is simply a classical model of a file system distributed across multiple machines.The purpose is to promote sharing of dispersed files.
Hadoop is a well-known framework used for big data processing now-a-days. It implements MapReduce for processing and utilizes distributed file system known as Hadoop Distributed File System (HDFS) to store data. HDFS provides fault tolerant, distributed and scalable storage for big data so that MapReduce can easily perform jobs on this data. Knowledge and understanding of data storage over HDFS is very important for a researcher working on Hadoop for big data storage and processing optimization. The aim of this presentation is to describe the architecture and process flow of HDFS. This presentation highlights prominent features of this file system implemented by Hadoop to execute MapReduce jobs. Moreover the presentation provides the description of process flow for achieving the design objectives of HDFS. Future research directions to explore and improve HDFS performance are also elaborated on.
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.

Understanding das-nas-san
1. Types of Storage…..
The three fundamental types of storage are….
• DAS (Direct Attached Storage)
• NAS (Network Attached Storage)
• SAN (Storage Area Network)
All three Storage types evolved over the years, Storage requirements and technology
advancement led to one another. In other words DAS led to -> NAS and in turn NAS led to -
> SAN.
1
4. Types of Storage….
DAS as its name implies is simply primary storage that is designed to be used by one and
only one computer.
Advantages:
Great for Mainframes and OLTP type high data intensive requirement.
Disadvantages:
DAS cannot share unused resources or data with other servers, and therefore it is also
called island of information.
DAS typically have limited scalability, Server has to be rebooted, creating downtime
during the installation process.
4
5. Types of Storage….
SAN provides block-level access to centralized storage. SANs were created in large part
due to earlier technology limitations associated with DAS & NAS
In the early 1990s, Windows and UNIX server vendors decided that they were going to
replace the mainframe. Within a few years they launched a project called “Mainframe
Replacement Program".
As we discussed in the earlier side, DAS was primarily used for Mainframe computing
b'cos of the Block-storage access, but due to many disadvantages such as unable to
share the disk and limited scalability issues, it led to the development of "SAN".
SAN is basically an extension of DAS, but more robust, shareable storage with highly
scalable.

7. Difference between NAS & SAN
Block Oriented Difference between NAS & SAN
The Wires being used:
• NAS solutions utilize TCP/IP based networks, such as Ethernet
• SAN solutions use Fibre Channel connections (Fiber/Copper)
The Protocols being used:
• NAS solutions use file level protocol (CIFS/NFS) and now also SCSI over IP called iSCSI
Protocol over standard Ethernet networks
• SAN solutions utilizes Fibre Channel encapsulated SCSI setups
7
8. Difference between NAS & SAN
FC-SAN communicates at the block level, with requests over the "wire(fiber/copper)" like :
•Read-block-thirty-four
or
•Write-block-five-thousand-and-two
NAS communicates at the file level, with requests over the "wire (Ethernet)“ like:
•Create-file-MyHomework.doc
or
•Read-file-Budget.xls
8
9. NFS uses 2 protocols - Mount & Directory file
Mount:
access protocol.
Client -> The client sends the pathname to the server and requests permission to
access the contents of that directory.
Server-> Checks whether the path exists in the /etc/fstab Or /etc/dfs/sharetab. If it
exists ? Y
Server-> Returns a "File handle" to the client (file handle contains-filesystem type,
disk ID, inode, security info.
Client-> Creates a In-kernel vfs mode (virtual file system) and mounts it to a
folder/directory.
Directory access Protocol:
Client-> sends RPC messages to the server to manipulate files & directories. File is
accessed by "lookup" RPC call. This returns :
a. File handle - using this file handle other parameters are passed such as -read
(handle, offset, count)this function will read count bytes from location offset in the
file referred to by handle.
b. attributes - such as size.
