Blade Server – thin, fast, and power plus space saving. That is how we can describe about this popular brand new server. Yes, blade server has become more and more famous with its pluses as described in my first sentence additionally with other great features it offers.

Cooling Capability
The first great thing about blade server is that it has cooling capability, which is actually really needed for blade server as it is requiring higher attention in this matter. During operation, electrical and mechanical components will usually produce heat.

However, with blade servers, its enclosures reduce heat by using fans. Blade is actually designed to produce less heat. But still, you need to ensure that the room temperature is cold (air-conditioned) as if it gets too hot, there will be automatic shut down.

Rack Based and High Density

Besides its cooling capability with its fan, blade server is also rack-based, meaning that you won’t spend too much space for servers. Being rack based, it can include up to 60 servers in the rack. So it is really space saving. And as you may have known, blade enclosure itself can hold multiple blade servers.

A blade server is sometimes described as server with high-density. Usually used in servers clustering, it is able to do any single task like sharing files, serving and caching web pages, encrypting the SSL of Web communication, trans-coding web page contents for smaller display, or even streaming audio and videos.

Less Cables, Less Structure Maintenance, More Availability Concentration
This must what you’ve been searching for, having less downtime. How? Well, blade servers allow more processing power in less rack space, simplifying cables and reducing power consumption.

When you decide to switch into using blade servers, you can reduce up to 85% reduction in cables for blade installations over the regular tower servers. With less cables, administrators can concentrate more on ensuring higher availability rather than spend time managing the infrastructure.

Networking Ability
Besides, blade server is also great for networking. Each blade server mostly has one or two local ATA or SCSI drives. And when it’s not enough yet,  blade servers can connect to a facilitated storage pool – Network Attached Storage (NAS), Fiber Channel, or iSCSI Storage Area Network (SAN) for additional storage.

So, as you’ve read, the benefits of using blade servers is not only the ability of it to consolidate placing tens of servers in a single chassis, but also additionally from the other advantages including the ability to associate with other resources (like storage and networking equipment), which is manageable through single interface.

Hello there! Here we’re again to provide you with the transparency of our Uptime record in November 2008. As we did in October, our availability was averagely 99.99% as guaranteed. And now, let’s evaluate our uptime in November to keep track on it.

November 2008 Availability Chart

Service % Time OK % Time Critical
FTP 99.990% 0.010%
HTTP 99.989% 0.011%
MySQL 99.992% 0.008%
SMTP 99.989% 0.011%
POP 99.990% 0.010%
IMAP 99.989% 0.011%

from the record in November, the uptime was tracked in several different services including FTP, HTTP, Email, and MySQL service as done in the previous month.

From the FTP service, we reached 99.99% of uptime and had 0.010% critical time record (downtime) tracked. The downtime recorded was resulted from the regular maintenance scheduled to improve all of our servers.

For the http service (website uptime), availability reached 99.989 out of 100%. There was 0.011% of service outage when there was regular maintenance to improve server performance.

Email service including POP, SMTP, and IMAP reached 99.99% in average for November, with only 0.001% unavailability recorded for regular maintenance.

And our database service even reached 99.992% uptime recorded and just had 0.008 unavailability tracked in the servers averagely from the scheduled maintenance.

Averagely in November, from all services in all servers, the availability of Host Department servers reached 99.989% out of 100%, which is rounded off to 99.99%.

It has been shown that so far, Host Department still meets their uptime guarantee. Well anyway, see you guys next month 🙂

IMAP 100.000% 0.000%
As pictured in the table, in October, Host Department averagely reached
99.994% out of 100% uptime for FTP service. There was only 0.006% critical
time when there was scheduled maintenance and data center migration.

On the other hand, the http service reached out of 99.996% availability and was in
0.004 % critical time in October for the website service. It was because we have scheduled
maintenance resulting in the service outage. 

For email services including SMTP, POP, and IMAP, we were available for 99.999% in average
in October, interpreting that we were passing over our uptime guarantee. 0.001% critical time
was for the regular maintenance.

Our database availabilty, MySQL, reached 99.996% averagely in October with 0.004% critical time
when there was scheduled maintenance and server migration.  

The Point from the Uptime Record
These uptime record is provided for all of our readers so that you can evaluate
 on how we rock on our uptime and we can keep improving our service now and then.
