Since I acquired the Acer easyStore Home Server, I have been trying to reorganize my digital library within the server. As the Acer easyStore Home Server came with 2TB of drive space, I quickly added a couple more 1TB drives I used to have with the old homemade Home Server to it to make it a total of 4TB in storage. After migrating all the files back to it, I was left with only about 0.8TB of free space. I was faced with a new decision, either deleting old files or add additional storage to the server.
I decided to add storage as I currently don’t have much time to go through my digital library to purge old files. There is no more internal drive bay available so the only way to add storage is by adding external storage. I was reminded by the unreliable “octopus” setup I had with my previous Home Server and I knew that is not the way to go. After researching a bit online and reading some reviews on wegotserved.com, I decided to give the Sans Digital TowerRAID TR4M-B a try. I got it from NCIX when they had it on sale for C$160.
It is available in 2 colors, black and silver. I got the black version as it matches the Acer easyStore Home Server.
The back of the packaging explains some of the RAID configurations. I am not interested in RAID setup at the moment. I am only interested in adding more storage as I can use Windows Home Server to replicate files for me, configurable per shared folder, to increase redundancy.
Deboxing the TowerRAID right on my desk. The white box has…
…some documentation, the eSATA PCI-X PCIe port multiplier, an eSATA cable, a power cable, some thumb screws and the software CD. The thumb screws are a nice addition as it makes it a lot easier to install drives without having to worry about a screw driver.
The TowerRAID sits securely under the white box. It is nicely packaged to protect it from damages via shipping.
And here is the TowerRAID outside of the box.
And the TowerRAID outside of the packaging. The case is very nicely painted. Almost like piano black all around. It is so shiny that I keep leaving finger prints on it….
The back of the TowerRAID has a good size fan for air circulation. The black cover is secured to the main case via three thumb screws. There are also a power switch, a regular power connector connecting to the internal power supply, an eSATA connector and a voltage switch.
Here is the Acer easyStore Home Server put side-by-side with the Sans Digital TowerRAID.
The TowerRAID is a bit shorter, not as wide and a bit longer in length comparing to the easyStore Home Server.
The Acer easyStore, even though it comes with an eSATA connector, does not support port multiplier. What it means is if you have an eSATA enclosure that takes multiple SATA hard drives, and you plug it directly to the easyStore Home Server’s built-in eSATA port, it will not be able to recognize the different drives inside your enclosure. This is where this port multiplier card comes to play.
It comes with a regular size bracket for regular tower case, as well as a short bracket for the small form factor tower case. The Acer easyStore Home Server comes with a small form factor case so switch the bracket is necessary.
Switching the bracket is very easy, it is secured on the PCB with only one screw.
Next, the Acer easyStore Home Server is opened up, the back cover of the slot is removed so that the port multiplier card can be inserted.
With the card installed, it is a very small interface card.
The back of the Acer easyStore Home Server with the port multiplier card installed. The card comes with 2 eSATA connectors. It is capable of supporting two external drive enclosures. Potentially I can add another TowerRAID to my Home Server.
I have 2 additional 1TB Seagate drives available from the old Home Server. Time to make them part of my server storage.
First, unscrew the thumb screws at the back of the TowerRAID case.
The inside of the TowerRAID is very simple. There are no drive brackets like the Acer easyStore Home Server. I really like this clean design as it makes installing drives a matter of sliding them into the slot.
As you can see, the fan sits behind the PCB of the TowerRAID. Some people comment that this will restrict air flow through the hard drives. It can be a consideration because the warmer the hard drives run, the shorter the life span they will have.
Looking at the TowerRAID from it’s front with the front door opened. The front door is made of plastic and the only concern I have is possible hinge damage if you are not careful. Under the door, from right to left, is the power light (square), the ready light (only lights up when the TowerRAID is connected to a computer), and the individual hard drive power/activity lights (green for power, amber for activity).
Drive 1 installed.
Drive 2 installed as well.
Using the supplied thumb screws to secure the drives.
Next, need to connect the Sans Digital TowerRAID with the Acer easyStore Home Server with the supplied eSATA cable. The cable is about 6 feet in length and does not look like cheap cables that are ready to fall apart.
After connecting the TowerRAID, I turned on both the TowerRAID and the Acer easyStore Home Server. The hard drives are not spun up until the TowerRAID detected a computer is connected to it. The printed documentation of the TowerRAID is a bit outdated comparing to the software CD I got. Fortunately, the CD also comes with some documentation that guided me to install the software driver for Windows Home Server (Windows Server 2003 32 bit in my case).
After the driver is installed, the new drives are available in the Home Server Console.
You can then add the new drives as part of your storage pool.
To further reduce the heat build up inside the Acer easyStore Home Server, I moved the two Seagate drives originally installed inside the Home Server to the TowerRAID enclosure. Moving the drives is just a matter of disconnecting them from the Home Server and plugging them inside the TowerRAID. Once the Home Server is booted up, it automatically recognizes the drives being part of the existing storage pool and there is nothing to configure.
Finally, I put the Sans Ditigal TowerRAID enclosure with the Acer easyStore Home Server in a storage case under my desk. This makes the already quiet server setup even quieter. I am loving this setup.
If you are looking for additional storage for your Home Server and you have an available PCI-X PCIe slot in your Home Server, I would say the Sans Digital TowerRAID is a good solution for the money.
clc4912 posted here his understanding of Acer easyStore supporting port multiplier out of the box without any additional port multiplier card support. I verified that his understanding is correct. I unplugged the TR4M from the e-SATA port on the PCIe card and plugged it directly to the easyStore e-SATA port, booted up the Home Server and all drives are recognized as before. Thanks clc4912 for the correction. So for the folks who wonder if they can use a plain e-SATA enclosure with the Acer easyStore Home Server without any additional port multiplier card supplied, the answer is yes.
And thanks Jeremy on http://mswhs.com/2009/09/11/expanding-the-acer-aspire-easystore-storage-capacity/#comment-17775 to help me correct my confusion of PCI-X and PCIe.
