A brief study on Storage Area Network (SAN), SAN architecture & its importance. It focuses on the techniques and the technologies that have evolved around SAN & its Security.
In presentation describe the structure of active directory architecture & also several components like object , attribute, Schema, Containers , Object Types, Data Model, Security Model & other components also describe.
Everything you wanted to know about iSCSI, but were afraid to ask. Presneted by David Black PhD who was a fundamental influence on the development of the protocol. This presentation is really fantastic!
The Network File System (NFS) is the most widely used network-based file system. NFS’s initial simple design and Sun Microsystems’ willingness to publicize the protocol and code samples to the community contributed to making NFS the most successful remote access file system. NFS implementations are available for numerous Unix systems, several Windows-based systems, and others.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
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.
2. How is data stored?
• Data that is accessed, modified, or written by a computer
(electronic device) is stored physically using some technology.
• The technology can be:
1. Magnetic Disk Drive
2. Solid State Drive
3. Optical Disk Drive
4. Magnetic Tape Drive
The type of disk used depends on factors like budget, I/O
requirement, longevity, and interface compatibility.
3. Magnetic Disk Drive
• In a magnetic disk drive, data is stored
on magnetic plates which are physically
accessed using a spindle and a
read/write head.
• Each plate is divided into sectors and
tracks.
• Performance measure: RPM, IOPS
4. Solid State Drive
(SSD)
• A solid state drive is made of non-volatile NAND
flash memory which is much faster than magnetic
disk drives.
• There are no mechanically moving parts in an SSD.
An SSD controller manages all I/O operations.
• There are mainly 3 types of SSDs available:
1. Single Level Cell (SLC): 1 bit per flash cell.
Highest performance and longevity but very
expensive.
2. Enterprise-MLC (eMLC): 2 bits per flash cell.
Most commonly used due to strong error
correction.
3. Triple Level cell (TLC): High density and capacity
but low performance and reliability.
5. Direct Attached Storage (DAS)
• Direct Attached Storage is data storage which is physically connected to a
computer using an interface.
• There are many types of interfaces:
1. USB: Rarely used for servers, common for users. 5 Gbps.
2. SATA (Serial AT Attachment): Used for SSDs. Inexpensive. 16 Gbps.
3. PCIe (Peripheral Component Interconnect Express): High performance but
expensive. ~2 GBps.
4. SCSI (Small Computer System Interface): Legacy. Many new standards based
on it. Popular protocol which defines a command set. 5 MBps.
5. SAS (Serial Attached SCSI): Replaced SCSI. Popular due to command set. 12
Gbps.
6. Network Attached Storage (NAS)
• Network Attached Storage is a storage device which is capable of being
accessed over a network.
• The NAS can be connected by a wire (through a server) or wirelessly (USB
ports on Wi-Fi routers/access points).
• It uses file based protocols like SMB (Server Message Block), CIFS
(Common Internet File System), and NFS (Network File System).
• A NAS is generally only accessed like an external drive on a computer
because it is a file-level storage.
• FTP is commonly used with NAS devices.
• E.g.: IETSRV02 (10.20.10.52)
7. Storage Area Network (SAN)
• A Storage Area Network provides block-level data storage to servers.
• A SAN acts just like an internal drive to a server. The processing is handled by a
storage controller (like a Network Interface Card).
• It is not necessary for a SAN to use Ethernet.
• A SAN cannot be accessed directly via a Local Area Network, it uses specific
standards like:
1. FCoE (Fiber Channel over Ethernet)
2. FCSAN (Fiber Channel SAN)
3. iSCSI (Internet Small Computer Systems Interface)
A SAN also allows for advanced features like multipathing, RAID, and storage
virtualization.
