Know the type of RAM used on your server

memory slots on Dell R720 takes Fully Registered RAMIn general, many do not enquire the type of RAM used on their server. What most really care is the “number”, like I’ve 32Gb RAM and blah blah blah…
Do you know there are different type of RAM used on desktop computers, entry servers and high performance servers? It is important to find out that your server are fitted with ECC or better RAM for stability, reliability as well as performance for your 247 online activities.

Most branded entry dedicated servers use ECC RAM. ECC is an extension to parity uses multiple parity bits assigned to larger chunks of data to not only detect single bit error, but correct them automatically at the same time. Instead of the single parity bit for every 8 bits of data, ECC uses a 7 bit code that is automatically generated for every 64 bits of data stored in the RAM. When the 64 bits of data is read by the system, a second 7 bit code is generated, then compared to the original 7 bit code. If the codes match, the data is free of errors. If the codes don’t match, the system will be able to determine where the error is and fix them by comparing the two 7 bit codes.

Registered memory has registers or buffers included on the module for better flow of data which increases data reliability. It also allows for greater memory scalability and larger amounts of RAM can be installed. Because of this, registered memory is used mostly in servers with ECC functionality.

Fully buffered memory or also known as fully registered memory takes some of the functions from the memory controller. The communication between the memory controller and the module is serial, thus less number of wires is needed to connect the chipset to the RAM. With serial communication, fully buffered RAM is possible to have up to eight modules per channel and up to six memory channels, this greatly increasing RAM performance as well as memory scalability. Fully buffered memory cannot be used on a server that takes registered memory or vice verse. Fully buffered memory includes ECC functionality usually seen on high performance workstation and server.

Find out who is eating your traffic?

When you click….wait, click again….wait again, click again and again….argh… 🙁 Sound familiar? That’s the sound like somebody has ran out of Internet bandwidth.
There’s a lot of things can drain out the capacity of that pipe that connects your web service to the Internet. It could be your bad neighbours on your network, or it could even be malicious application or services are running on the same network. The problem can get so bad that some customers will toss out their computer and buy a new one.
However, many web hosting subscribers are not aware this can be avoided and the problem could lie with your web host network setup. If you have noticed there’s a characteristic and pattern of this network hiccup, and it always happens on a specific period daily, maybe during wee hours?

If this is the case, your web server might be relying on a single network cable to perform all the tasks which includes internet, back-end management and backup. Yes, you hear me, it’s done on one single cable where your public internet traffic and backup traffic co-existed.

This poses 3 serious issues;

1. All your stored information is transmitting publicly during backup. This increases the risk of exposure on personal data.

2. The other serious event, backup traffic has clogged up your traffic to the internet. Generally speaking, backup traffic volume is much higher compare to the genuine internet traffic. When this happened, connection to your website becomes slow or inaccessible.

3. Since backup traffic uses the same network cable for your internet connectivity, the consumed traffic might have included your backup traffic. Which means, your consumption might be way lesser than what you were billed.

Vastspace segregates traffics into internet traffic, backup traffic and management traffic on three network segments. Each segment has at least one network cable for each kind of traffic.
