Anonymous asked:

Really awesome post! 🙇‍♀️ Some of what you shared is beyond my understanding 😅 but that also makes it educational (thank you for the links to sources, that HEVC haunted link!) Also the bit about upscaling decisions 🥲 I don't think we can make assumptions about how long things last on the "internet" (harder to find 🥲, removed/made private, etc.), so I definitely appreciate your effort to archive/back up stuff 🫰🙇‍♀️

This is a fake ask because I wanted to remove the links at the bottom (I appreciate them, just nervous about re-sharing) but did want to respond to the rest of it. Specifically, if you are even moderately interested in my nerd tangents, I cannot pass up the opportunity to gush about how cool RAID is as a concept.

You’re right that everything on the internet either lasts forever or just not long enough for you to save it, depending on what is most inconvenient at the time. It is both an access and a preservation problem. The YouTubes of the world aren’t likely to lose data accidentally (just deliberately stop you from seeing it) but as soon as you start trying to make personal backups you have to factor hardware failure into the equation. Disks fail. Backblaze publish some cool statistics on exactly how often. Keeping a backup of anything critical on a single hard drive is playing with fire, it's not a matter of if, it's a matter of when if you have plans to keep it for more than a decade (although they do show warning signs, so if you're regularly monitoring S.M.A.R.T test results its less likely to happen completely out of the blue).

My backups are currently stored in a RAID 5 configuration (specifically, a ZFS RAIDZ1 pool). That means I can yank any of the four disks out at random and everything will continue operating completely normally. In the event of a drive failure, inserting a new empty drive of equal or greater capacity will allow the system to rebuild the content the old one was holding onto the new one, resulting, upon completion, of a configuration that once again allows any disk at random to be pulled without data loss. The main vulnerability here is that two failures in quick succession are completely unrecoverable (the contents of 2/4 drives are utter gibberish and cannot be deciphered without at least one more from the original pool). My drives are purchased from different batches but from the same manufacturer, so there is still potential for common cause failures (one of the risk factors also just being that they are of similar ages). When I originally built this system I was happy with the level of risk involved with a rebuild event, but recently I've been thinking recently of moving it over to a RAIDZ2 (two disks of redundancy) instead. It isn't possible to "upgrade" an existing pool like that you have to do a complete rebuild, but my friend has an external backup server on my local network (well, its not, it's currently in a separate VLAN, but that can be changed) I can use to temporarily shift my stuff over to before moving it back. The new pool would be 6 wide with 2 disks of redundancy as there's no point in RAIDZ2 with 4 disks (that's just a mirrored pool) so I would also gain a disk's worth of capacity in the progress, but lose two disks worth of money from my bank account, which is why I haven't done it yet.

Oh also, as a final note, computers are not as infallible as they are made out to be. While the chance is very low, it is never zero that a cosmic ray causes a bit flip somewhere critical and unrecoverable to the program which needed it. Ever had a completely random crash that you've never been able to reproduce? Well, it probably wasn't a cosmic ray. But it could have been! This is the kind of stuff I think about for a living ;)

Meaning of Bare Metal Server?

To understand the meaning of a bare metal server let’s understand the meaning of a web server, A web server can be said to be software or hardware that stores all the website’s files responds to client requests, and delivers the required files accordingly via the internet. The Meaning of Bare Metal server in simplest words can be said as a server that is created for a single person only with the most premium technology that can be availed in a physical server only i.e. it cannot be available virtually.

Meaning of Bare Metal Server

A bare metal server is a physical server, it is a kind of server that is dedicated to a single tenant, In a virtualized server the hardware resources such as CPU, RAM, Storage etc. are shared while here all of the resources are used by a single person only and are chosen as per our choice, as there is no co-dependency in this kind of server it not only facilitates the increased performance of the server but also reduces hustle as it removes additional layers of software that are put into making server services available virtually.

Here there’s also an additional benefit of making the server as customized as possible, As there is only a single user and the server is available physically, It can be created to please and cater to your needs. let’s understand how it can be customised to an extent:

Personalized selection of hardware components such as CPU, type of RAM, and Storage.

There can be an option to choose any kind of Operating System that is compatible with your website

In a bare metal server, you can have firewall rules to suit your application’s requirements which include defining IP addresses, setting up virtual LANs (VLANs), managing network security policies, etc.

In a bare metal Server, there is access to the server’s BIOS (Basic Input/Output System), which allows for low-level hardware configurations, such as hardware virtualization settings, and power management options.

Understanding the Difference between a Dedicated Server and a Bare Metal Server

As the working of bare metal server and dedicated server is quite similar, they both have resemblance such as they both are dedicated to a single tenant but they can’t be said as the same, The root difference doesn’t lie in the product but the working of the server the concept of bare metal servers arrived after some drawbacks of a dedicated server.

While a dedicated server provides multiple benefits it has some inevitable drawbacks such as dated hardware and long provisioning times. However, bare metal servers typically come with the most advanced hardware and software. They are a hosting provider’s prized asset or flagship because bare metal servers are specifically made to automate the provisioning process, they may be put up more quickly.

The hardware provided by bare metal servers is considerably more similar to a cloud service framework, with installation durations measured in minutes or hours and hardware ranging from low-cost to Top-of-the-line components, including graphics processing units (GPU). When it comes to hardware, bare-metal servers have an advantage thanks to their use of the most recent Intel Xeon processors, DDR4 RAM with Error Correcting Code (ECC), and NVMe solid-state drives (SSDs) rather than SATA SSDs and hard drives. Because of the combination of these components, In conclusion, bare-metal servers stand out as a high-performance hosting solution.

What is IPTV (Internet Protocol television) and how to let router connect to it?

What is IPTV (Internet Protocol television)?

IPTV (Internet Protocol television) is a service that provides television programming and other video content using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, as opposed to broadcast TV, cable TV or satellite signals.

An IPTV service, typically distributed by a service provider, delivers live TV programs or on-demand video content via IP networks.

An IPTV system may be used to provide video content over a private network in an enterprise, although such implementations are far less common than subscriber-based models due to the complexity, network latency and scaling issues.

How to let router connect to IPTV?

To let a router connect to IPTV, you need to configure the router to support IPTV and connect the IPTV device to the router. Here are the general steps to follow:

1.Check if your router supports IPTV. Some routers have built-in support for IPTV, while others require additional configuration. You can check the router's manual or manufacturer's website to see if your router supports IPTV.

2.Configure your router for IPTV. The exact steps may vary depending on your router model, but generally, you need to configure IPTV VLAN, IGMP Snooping, and QoS settings. You may need to consult your router manual or manufacturer's website for specific instructions.

3.Connect the IPTV device to the router. You can use an Ethernet cable or Wi-Fi to connect the IPTV device to the router.

4.Set up the IPTV device. If you are using a standalone IPTV device (such as a set-top box), you may need to configure it to work with your router. This may involve selecting the appropriate network settings and channels.

5.Start the IPTV service. Once the IPTV device is set up and connected to the router, you can start the IPTV service and select the channels you want to watch.

🔍 DHCP in SDA Fabric: A Closer Look! 🔍

Post:

Hey there, network enthusiasts! 🤩

Welcome back to our SDA Technology Pillar Series! Today, we're diving into the world of Dynamic Host Configuration Protocol (DHCP) and seeing how it works its magic in our Software-Defined Access (SDA) fabric.

So, how does DHCP play nice in our SDA fabric? 🤔

Centralized Management: In SDA, DHCP is centralized, with a DHCP Server managing IP addresses and other network configuration details. This makes life easier for us admins, as we can control everything from one place. 🏢

DHCP Relay: To reach our centralized DHCP server, DHCP Relay Agents are deployed on Edge Devices (like switches and wireless access points). These agents forward DHCP requests from endpoints to the central DHCP server. It's like having a helpful postman delivering letters between you and the post office. 📮

DHCP Options: SDA uses DHCP Options to pass along important information to endpoints, like:

VLAN ID: Tells endpoints which VLAN they should join.

Policy: Applies network policies and quality of service (QoS) settings.

DNS Server: Provides the DNS server IP address for name resolution.

DHCP Snooping: To keep our network safe from rogue DHCP servers, SDA employs DHCP Snooping. This feature checks that only authorized DHCP servers can respond to requests, blocking any imposters. 🕵️‍♂️

IPv6 Support: SDA also supports DHCP for IPv6, using DHCPv6 to manage IPv6 addresses and other configuration details. It's like having a separate, more private post office for your IPv6 letters. 🌍🌐

But why centralize DHCP, you ask? 🤷‍♀️

Simplified Management: A single DHCP server makes it easier to manage IP addresses and network policies.

Consistency: Centralization ensures that all endpoints receive the same network configuration, reducing errors and inconsistencies.

Security: By controlling DHCP, we can better protect our network from unauthorized access and malicious activity.

So there you have it, folks! A closer look at how DHCP keeps our SDA fabric running smoothly. Stay tuned for more under-the-hood adventures in our SDA Technology Pillar Series! 🚀

Until next time, keep your networks configured and your curiosity piqued! 🔒🧠
