When you are networking computers, wireless access points, printers and other nodes in multiple rooms, try to avoid daisy-chaining switches or using small 4-8 port switches when you are in a hurry. Replace any hubs on your network as soon as you can.
With a hub, collisions can be >20% and utilization can stand at >50%. By replacing a hub alone, you can reduce collisions to 5% on switches in rooms and <1% in the server room. Switches help to isolate traffic, relieve congestion, separate collision domains (reduce collisions), segment and restart distance/repeater rules.
Daisy Chaining Switches -what not to do
Real world scenarios may require you to temporarily daisy chain switches. If you do, test the network and run additional backbones or replace core switches to accommodate more nodes as soon as you can. (remember, replace any hubs in your network)
One of many solutions is to run independent lines to the core switch
This is the very basics behind network switch infrastructure. Managing switches and using the IEEE standards above along with optimizing your network and managing the network infrastructure is important.
Over-provisioning is the allocating of a specific amount of free space on your SSD. Over-provisioning improves SSD endurance and performance. Many SSDs are packaged with software that helps the end user install the drive and to plan for OP. (More advanced drives are doing away with OP).
The SSD controller manages all of the data that is stored on the drive. While these drives are really fast, data writes are not just placed on the drive. Data is moved around and the controller on the drive is programmed to use the drive evenly across the NAND blocks. By moving the data around, the controller can use the free space (OP) to swap information as needed. This in turn adds life to your SSD. Always update your SSD firmware, use the manufacturer’s software for OP if your drive recommends it and don’t forget to trim your hard drive. TRIM allows for the removal of junk or old data. How? Easy – Open a command prompt (as Admin)
Type the following – fsutil behavior set DisableDeleteNotify 0
Over-provisioning in Samsung Magician’s software.
Always load the drivers – Below is Intel Drivers on my laptop vs. Windows 8 generic drivers
Windows 8.1 SSD Optimization
If you have install an SSD to Windows 8 or 8.1, and you aren’t sure if the OS is optimized for an SSD. Here’s the fastest way to make sure it is optimized.
Open a CMD prompt as an Administrator Run winsat formal Defrag will remain on, that’s right, on. After ‘seeing’ the SSD, this tool (defrag) will become optimize and will trim your SSD. Of course AHCI should be on, over provisioning accounted for and the proper chipset drivers loaded.
Want to extend your network and make it more reliable and robust?
Here’s what you will need -
Two routers with the same firmware
Preferably Tomato or DD-WRT
Login to the first router.
In this example, the static number 192.168.1.1 is the Main router.
Enable the WAN to match your ISP
Enable Access Point + WDS (Picture two below)
You must have the same wireless configuration on both routers
Enter the MAC address of router two under WDS Link with.
Login to the second router
Disable the WAN
Assign the router a static IP address (Below we have given the router .250)
Enter Router One’s IP Address for the Gateway
Enter a DNS of your choice
Make the wireless configuration the same as the first router. Under WDS, change the drop down to automatic.
With the same settings, you can now extend your network several hundred feet under the right conditions. Because the SSIDs are the same, once you join one of the routers with a smartphone or laptop, it will seamlessly change to the stronger signal.
With Tomato, you can chain together approximately 12 devices.
I usually don’t review hardware products but I felt a need to review HP’s Pavilion 11t-n000 x360.
My father-in-law wanted a Microsoft Surface but still wanted a keyboard and the functionality of a laptop. He also wanted to avoid the expense of a Microsoft Surface and wanted something with a small profile, light weight, lots of storage and plenty of ram for traveling. He found the HP Pavilion 11 x360 that has the following features:
Quad core Pentium 2.17 Ghz
Windows 8.1 64bit
4 GB DDR3
500 GB HD
less than 1″ profile
Screen 11.6″ (Touchscreen)
Gyros built in
1 -USB 3.0
2 -USB 2.0
5 hour battery life (45 watt AC adapter)
SD Mediacard Reader
12.12 x 8.46 x 0.86 in
1 year warranty
I expected the laptop (netbook?) to be slow. I was surprised at how responsive it was with 4GB of RAM. It is by no means a powerful gaming computer but is a match for home, business or school users. The pc is upgradeable to 8GB and a hybrid hard drive which would make a difference in performance. Is this necessary for the typical user? Probably not.
Once you setup a Microsoft account, Windows 8.1 has the Microsoft store (which now has over 400,000 apps ) and OneDrive to backup and sync pictures, files and more.
With the HP Pavilion 11, you can fold the keyboard to have a tablet or you can flip the keyboard down and use the pc in ‘tent’ mode so it supports the tablet functionality. Folding the keyboard under the touchscreen gives you a tablet. The touchscreen is very responsive to the slightest touch.
At $399, I don’t know why you would buy a laptop or a tablet.
