2 Servers, 1 UPS

2 Servers, 1UPSWith the new server up and running it seemed fitting to connect it to my UPS, and thanks to the low power consumption of the HP Microservers I still get around 40 minutes of battery only time with both servers running before the UPS runs out of juice.

Unfortunately, the UPS in use only has one monitoring port which is connected to my original server, meaning during a spell of prolonged power outage, the new server will not know when to shut down safely and will continue to run until the UPS runs out of battery supply, leaving it vulnerable to data corruption that affected the original server prior to battery backup.

But with a simple script and some setup both servers can shut down safely before the batteries run out.

Raspberry Pi 2

The Raspberry Pi Foundation has brought a new model of the Pi to the table, so with the same low price it was easy to add to my Pi family.

Raspberry Pi 2

For those not yet familiar with the RPi 2, it keeps the small and simple form factor of its predecessors, but gives performance upgrades in the form of an 800mhz quad core processor, with overclocking options still available, and combined it with a whole Gigabyte of RAM. These upgrades, on paper at least sound that it could make the Pi into a useable desktop machine, with less freezing during full CPU load that was easy to achieve previously.

Trouble Accessing BIOS with Windows 10?

Since installing Windows 10 the option to enter BIOS settings disappeared on my HP Pavillion DV8, with the only way to get it back was to pull the CMOS battery from the laptop and perform a hard reset.

If you’re having the same trouble the solution is easy, instead of clicking shut down to turn off the laptop and switch it on again, click restart instead! Seems simple but I always used shut down to allow the machine to cool off before turning on again.

Finally: Fibre Connection

Fibre broadband has been available in my region for a couple of years now, and while it was tempting it was just too expensive for a fully unlimited package. Therefore I had to make do with ADSL, combined with being a few miles from the exchange it was pretty poor, even when pulling the ring wire.

But at last an offer from Sky for existing customers to get Fibre half price, so I had to jump on this bandwagon immediately. The Fibre To The Cabinet (FTTC) service is a 40Mbps down and 10Mbps up with no download cap. Compared to before this is a huge improvement.

New Server

My trusty HP Microserver N36L has been ticking along nicely for years with Windows 2003 at the helm, but with support for 2003 coming to an end an alternative was needed.

Recently I have been using Amazon EC2 cloud services for all my website hosting, new customers to the service get a 12 months free teir1.micro instance with myself opting for Windows Server 2012 R2 as my OS, and I’ve taken up this offer since October last year when an extended spell of server woes left me unable to serve websites.

A caveat with the free EC2 instance is the billing process, while the instance is free you have to pay attention to what is included as part of the offer, network usage, hard drive capacities and security keys are subject to charge over certain thresholds, so be aware.

With the trail due to expire in a few months I preferred to avoid an ongoing monthly cost and bring website hosting back to my own server, but not my current server as I didn’t want a box that served the web as well as store all my personal files. The logical conclusion was to get a new server.

Want A Faster Network? Check Your Cables

I have been running Gigabit Ethernet on my network for a few years, the speed from my everyday laptop was good enough at 40MBps but wasn’t running close to capacity when moving large files to the server, I assumed that this was down to the 5400rpm Hard Drives on the laptop not being able to fill the bandwidth on the network.

Recently while shopping for network cables to connect my new server I though it time to get a new line for the laptop since the plug clip on the current one was broken. I decided to go for Cat 6 cables just to keep up to date and nowadays there is not such a price premium over Cat 5e.

The first transfer of data through the new cable and instantly got 70MBps, nearly double the 40MBps I was getting before. Wondering why there was such a difference I looked at the replaced cable:

First Look At Windows 10

I just got my first hands on look at Windows 10, before I even start I must note that this is not going to be an in depth review of the system as I am just hopeless at writing reviews, so instead here are a quick few pointers of what I noticed.

Upgrading RAID Disks

The time came when my 1TB drives were full, having a data clearout reclaimed a bit of free space but it was time to upgrade.

The HP Microserver I am running has four HDD bays all populated with 1TB drives in RAID 1 configuration, so to increase capacity I had to replace two of the disks. I went for two Western Digital Green 2TB disks as the 1TB variants I currently had proved reliable.

Moving the data over to a new disk would be tricky, the simplest solution would be to put the old drives into a USB caddy and plug into the server, but I had previously found that USB drives don’t like RAID. But since RAID1 means redundancy, I could tackle this another way…

UPS Investment

From the last post, the idea of having UPS in my home may put me off forever, but to put it into context the unit had been installed before I was employed over 12 years ago, and over the past 2 years it was beeping intermittently to indicate a fault that a convenient press on any button would silence.

The post before that however had more gravitas, with my server being offline for close to a month all due to a one second power cut made me feel vulnerable to another downtime incident over something I couldn’t control. It was time to look into a Uninterruptable Power Supply to protect my server from power cuts that could knock my RAID out of sync.
