IBM BladeCenter HS22

The challenge was given by IBM to test Indonesia BladeCenter HS22 series servers are entered into the ranks of the product division STG (Systems and Technology Group) at IBM Indonesia. Of course, we do not miss this opportunity. Unit testing using a chassis series H.

In addition to 14 slot blade servers, chassis serial H able to load 2 fan or blower units that are redundant, the switches 4 units each with 4 LAN RJ45 slot, as well as 4 power supply units are redundant and hotswap plus have the ability to load balancing and fail-over. Each power supply also has an additional fan for cooling.

If the admin wants to use the console directly, the H series chassis is also available with a KVM station to the monitor port, USB port for keyboard and mouse, and the RJ45 port to enter into the web interface remote server management.

Through the web interface server administration, admin can do many things, including: selecting and activating each blade server, forming a series of hard disk (RAID), install the operating system, manage IP addresses on each LAN port, directing the blade server to storage, directing the use of the console (terminal) keyboard and mouse and VGA to a specific server blade, and so on.

IBM provides an application called the IBM Server Guide that will make it easier if admin chose to use the Microsoft operating system Windows Server on one bay BladeServer HS22. This application provides a variety of hardware drivers that are generally required by the operating system.

No lag, IBM includes an application called IBM Systems Director to facilitate the management of virtualization. With this application, admin can view the status of each blade server that may use different operating systems are different. Admin can define how each system is connected. Visually, all the components can be monitored, including servers, storage and networks.

 HS22 blade servers that we tested uses IBM 59Y5667 motherboard, a processor socket 2. Test unit 1 is filled with quadcore processor E5530 Intel Xeon 2.4 GHz-speed computing and Gainestown codename. CPUZ tool that our latest release pairs used to recognize the chipset as an Intel motherboard Rev. 5520. Intel 13 and 82801JR southbridge (ICH 10R).

To support the main computing, HS22 Blade Server equipped with a chip RAM DDR3 triple channel types that can accommodate up to 96 GB. Meanwhile, our test unit with 6 GB of memory.

Pair disk hotswap SAS becomes the locus for the operating system on HS22 Blade Server. Each 146 GB hard drive capacity and speed turn 10,000 rpm. Thus, the two hard drives can be arranged in RAID systems RAID 0 or 1.

Okay, let's look at the performance of this server blade. We employ two types of tests. The first test aims to see the performance of each major hardware component separately. We used SiSoft Sandra Lite tool's latest.

While the second test aims to see the performance of the hardware in the run synergy between components of one server function, in this case as a web server. In this second test we installed IIS as a "machine" and put the web page HTML and ASP pages contain complex mathematical calculation. In the computer test, we installed a tool Paessler Webserver Stress Tool that will output Whack a target server with requests for HTML pages and ASP up to 2000 requests per second, for 10 minutes.

Optimal user (active user)	280
Maximum HTML user/client (active user)	973
Maximum ASP user/client (active user)	973

Web server stress test results show that the error handling of HTML pages occurs on the user to 973, as well as an ASP page error handling. Blade Server HS22 looks still pretty responsive handling requests, less than 1000 milliseconds, up to 280 users. From our observations, there is a very significant difference in the optimal components of a user between servers that use Intel Xeon processors that use the E5530 with Intel Xeon E5550.

So you can easily be listened to, we show the results of individual performance test every hardware component in table form. Broadly speaking, we see good performance on multicore efficiency components (processor), memory bandwidth (processor), and File Systems (hard disk).

IBM BladeCenter HS22 displays excellent performance that should be the choice solution to the needs of enterprise-class servers are fast, have the flexibility of expansion, practicality in virtualization, and integration management of many servers at once.

D-Link DIR685

More wireless network devices are required to be multifunctional. Well, let's refer to bid on this one: a wireless router that can load and use shared-disk but also the aesthetic appearance as an electronic photo frame.

That's trilogy of functions that are presented by D-Link wireless routers in series and given the nickname DIR685 router storage. Not only 1-inch hard drive capable of 12 shared by this router to the network, but also a kind of portable media save flash (via the USB 2 ports on the back of the body). There is also thorough, there are 4 LAN RJ45 ports to support network connections via cable and RJ45 WAN port 1 to connect to the Internet via a modem.

For an aesthetic impression strengthened, D-Link DIR685 using internal antennas, which means Eliminating the possibility to replace the antenna with a more sensitive or more powerful radiance power. However, the 802.11n wireless standard speed 100 Mbps data transfer adopted by D-Link DIR685 is expected to compensate for this.

An LCD screen measuring 3.5 inches in addition to functions for managing network configurations, monitor status, and network conditions, as well as a media viewer, the pictures in the media store. System configuration settings using the four direction buttons in the next layer. Again, for the sake of aesthetics, the key used is not outstanding, but flat with the surface of the body of the router.

Parameters that can be displayed and arranged on the LCD display among others, Statistics including connection speed (cable, wireless and internet), which includes status and connection status of hard disk status, WPS to enable wireless security systems, point to Settings to set the time LCD and hard drive hibernation and LCD brightness levels, Photos to manage change interval display images and media source or penyimpannya, and Frame Channel.

Also there are several configurations, such as the establishment of user accounts and group NAS, the level of data access rights of each user, setting the FTP server function, other than formatting your hard disk menu interface via the web. Uniquely, the file system used to format the hard drive is EXT3, typical Linux or UNIX systems.

Routing the existing facilities on this router and is used to set the paths in the network data packet can not be considered trivial. In addition SPI firewall to protect against DoS attacks (Denial of service), this router provides a firewall that can be added to the rule. In addition, there are features Demilitarized Zone (DMZ) to isolate the computer within the network are allowed to be accessed directly from the Internet, Port Forwarding to direct requests from the Internet to computers in a network that are listening on port services, Web Filtering to filter the site address Web prohibited (blacklisted) or otherwise permitted (whitelist), and Dynamic Domain Name Service (DDNS).

Our initial suspicion of not maximum data transfer speed (throughput) wireless on D-Link DIR685 because it uses an internal antenna with irrefutable test results using the NetIQ Chariot tool. Recorded, on the condition of free space partition and 13 meters distance between the router with the computer examiner, D-Link DIR685 provide maximum throughput of 83.507 Mbps, 51.381 Mbps minimum, and average 76.029 Mbps.

Throughput numbers are not moving far, when we try to move the Dlink-DIR685 into an insulated space and a hole with the same distance. Maximum throughput remains located at 82,816 Mbps rate, a minimum of 39,043, and 76,610 Mbps on average.

The router shows a satisfactory test results, not just on the throughput performance, but also the performance of the SPI firewall. We are positioning this as a gateway router and connect it to the test facility's Shield Up Gibson Research Center (grc.com) through a public IP address. All the service port (service) is in hidden status (Stealth).

***

D-Link DIR685 presents a multi-functional aspects as better value product. This aspect does not reduce the basic performance, ie data transfer speeds (throughput) as an access point, various routing functions, and firewall security. Very suitable for use in the room, gallery, living room, even the extra wide space.

Rainer SV110C2-3.0 SATA35F

For this reason, Rainer brings server package "frugal" which berbundel operating system Windows Server 2008 R2 original Foundation, aimed at the small and medium enterprises (SMEs). Why the label R2 Foundation? This means that this operating system will record the number of login sessions in the same time a maximum of 60 users.

Each purchase of this server package will be accompanied by a CD containing the operating system image as a backup. Installation requires re-arranging the operating system hard drive 2 Seagate Cheetah 250 GB ST 3250310NS SATA connection to the first RAID system through the BIOS. After that, then, the installation can be run by booting from a CD image of Windows Server 2008 R2 Foundation.

The circuit is bundled disk RAID uses only 1 of 5 SATA ports available on this server motherboard. SATA cables used to connect the branches 2 hard drive to one of the SATA ports.

What about the hardware specifications of its components? At first glance, this server looks like a regular desktop PC. But after opening the right side panel of its chassis, it would seem that the motherboard and processor are specific to the server. CPU Z Tool latest release we install the unit tests provide information that used a single processor is Intel's dual-core Xeon E3110 with 3.00 GHz clock speed and 6144 KB L2 cache and name password Wolfdale. While its motherboard is Intel 3210SH.

Although not as much memory slot series Rainer another server, 4 memory slots filled with 1 memory chip brands Visipro capacity of 1 GB DDR2 EEC PC6400 (error correction code) is sufficient for the SMEs.

Computing servers running heavy anticipated by 1 fan 9 cm in diameter attached to the processor heatsink, 1 fan 9 cm in diameter on the rear panel chassis, 1 fan diameter and 12 cm which is one of the power supply (PSU).

In addition to the fan, the chassis rear panel there are PS2 ports for keyboard and mouse. A pair of RJ45 port of the network card speed 1000 Mbps (gigabit Ethernet) is also available on this section to support the transfer of high-speed data packet.

Our time has come to test the performance SV110C2 Rainer server-3.0 SATA35F, either as a single unit in running a service function, as well as individually on each hardware component. Test results of individual hardware components through the tool SiSoft Sandra Lite tests we display in table form for easy listening to. In general, we found a good enough score on the element multicore efficiency, memory bandwidth, and memory latency. RAID performance elements reflected in the file system is also quite good in the buffered write, sequential write and random write.

Function as a web server we choose to test the performance of hardware synergy between the components. For that, we installed IIS Web server machine as well as HTML and ASP pages contain complex mathematical calculation. On the other hand, the test computer we installed a Web server stress tool that will spray the target server with requests for HTML and ASP pages as much as 2000 times per second for 10 minutes. In order to avoid the bottleneck of the data packet stream, we connect the server and test computer with gigabit ethernet devices and CAT5E cable.

Graph Web Server Stress Tool test showed that the error handling of HTML page requests occur on the user 404, whereas for an ASP page, place the user to 801. This server is also still capable of responding to requests web pages quickly (less than 1000 milliseconds) to the user to 253.

Bids bundle Windows Server 2008 Foundation is more value on the package server-3.0 Rainer SV110C2 this SATA35F. Performance as a web server pretty good, also his performance RAID, so take this server package as an alternative solution for the SMEs. In our opinion, to consider improving server performance with an additional investment DDR2 memory chips.

Physical Design Allied Telesis AT-WR2304N is quite exotic with a milky white color and compact size approximately setangkupan palms. A pair of "horn" antennas that can be removed-rates indicate that the wireless router uses the 802.11n wireless standard, which means the data transfer speed should be close to 100 Mbps.

At the back of the body of the wireless device is available 4 ports RJ45 cable for local network (LAN) and 1 port RJ45 cable to connect to the Internet (WAN).

Meanwhile, in the front row of LED's there to monitor the status of traffic in each data packet and the status of the LAN ports hostspot. For ease of setting the security settings, the producer Allied Telesis AT-WR2304N adding WPS button (Wireless Protected Setup) on the rows of LED lights.

Entering interface web-based settings, we did not find many special features on this wireless router. But the feature map port, port forwarding, and NAT collected on our Advanced menu value because the value of giving more freedom for middle-level administrators in designing and managing the routing of data packets.

Featured monitoring (monitoring) of traffic data packets on the menu System> Monitor and displayed in the form of bars, we are value-added convenience features work administrator. View this chart is updated every 5 minutes.

Uniquely, in addition to a firewall that can be customized and scheduled to filter data packets, Allied Telesis AT-WR2304N have a power saving feature which can also be scheduled. In practice, this feature can be used, such as after office hours and not many people who use hotspots.

Allied Telesis AT-WR2304N successfully passed the test throughput (data transfer signal strength) with a pretty good value. In the test room without the screen that stretches at a distance of about 13 meters, NetIQ Chariot tool recorded the highest throughput in the number 81.301 MBps. The lowest throughput of 6.047 Mbps rate, and the number reratanya at 55.727 Mbps.

When he moved into the space and berlorong breakout, the same distance, this router brings 58.824 Mbps peak throughput, the lowest value of 11.211 Mbps and 42.065 Mbps average. These achievements fairly pretty good, considering that when we see the response time average is small enough and far below 5 seconds, ie 1.901 seconds. That is, the router is quite responsive and fast as forwards the packet data.

We also provide secure title to the firewall SPI (Statefull Packet Inspection) congenital Allied Telesis AT-WR2304N. Because when placed as a gateway at the front and connected to the test facility's Shield Up grc.com (Gibson Research Center), all communication ports in the state of hidden (Stealth).
