In regards to the additional products, we have a skin installed and we have a product that we had custom developed for us that connects to a PostgreSQL database. We've looked at slow PostgreSQL queries causing problems and have not been able to find an issue. We've also tested for the case where the PostgreSQL server is down and have not been able to create an issue. We therefor...
Information technology systems are an essential and
strategic component of every enterprise and every building. For those who
design and manage Enterprise Information and Communication Technology systems,
the guiding principle has always been - Better, Faster, Cheaper. Give clients
better performing systems to achieve results faster and reduce costs. Today a
new element has to be added to that mandate - environmental responsibility.
According to IDC, energy and cooling expenses will grow eight times faster than
the amount of money spent on purchasing new servers through 2010, warns APC-MGE,
a global leader in power, cooling, and management solutions. Predictions show
that changes in power supply and cooling in data centers will have a serious
impact on users, suppliers of data center solutions and energy sources. In fast
growing regions such as the GCC, power is in short supply. This calls for
technology solutions that address this challenge fast.
The majority of existing data centers (and some of the new ones being
implemented now) are not suitable for operating high-density systems. Data
center suppliers and operators must change their approach to apply the new
technologies. "The presence of higher power in data centers will directly
affect all users.
IDC predicts that in 2010 the amount spent on cooling and powering the existing
installed base of servers will be over 70% of what is spent on purchasing new
servers," warns Christian Bertrand, ME Business Development & Support
Director at APC-MGE. "Building completely new data centers might be
cheaper than reorganizing conventionally-built ones, even in the medium-term.
We could say that the data center design methodology of yesterday, the
conventional server technologies and today's requirements together will form
the greatest IT challenge of tomorrow," added Bertrand.
Information systems provide an increasingly ubiquitous network within the
companies, and offer services in new fields. Using this network, companies can
provide faster and better services to their customers, including RFID and VoIP
solutions. The emerging and broadening information services also induce changes
in data centers; they require more servers and processors, higher network and
storage capacity. Due to these changes, IT professionals face the following
challenges:
Speed and Agility: The world of business that requires increasingly faster
response relies more and more on information systems. The imperfection of an
information system must not hold back the launch of a new service or project.
In addition, this must be provided in a solution where investment grows with
revenue: "Pay as You Grow". Impact on the infrastructure: modular and
scalable solutions are needed for power supply and cooling.
Footprint, rental costs, and expansion possibilities: Placing more equipment
requires more floor space, requiring constant expansion of data centers. The
costs associated with occupied areas (for example rental costs) limit expansion
possibilities, particularly in downtowns, and in several cases server rooms
cannot be enlarged due to the lack of free space in the building. Area
limitations motivate IT professionals for dynamic growth, namely they have to
provide higher performance by server consolidation and high-density
applications using the same floor space. This solution can be implemented by
using 1U and blade servers, or virtualization technologies. Impact on the
infrastructure: higher power consumption, higher power density, and overheating
problems when using conventional cooling methods.
Security requirements, availability: The increasing amount of stored data,
threats entering through e-mails, fear from terrorism and higher availability
requirements demand more secure systems with higher availability. This trend is
also fuelled by different requirements, regulations and internal policies (Basel 2, SOX, BCP[1],
DRP[2], etc.) The fastest possible restoration after an unplanned downtime is
becoming an even more important factor not only for information systems, but
also for server infrastructure: instead of MTBF[3], MTTR[4] is becoming the
first priority. In case of IT devices, this change drives the emergence of
modular systems and virtualization. Impact on the infrastructure: emergence of
easily reparable modular solutions, increased demand for comprehensively
manageable equipment.
Cost reduction: This is a general and ever-increasing requirement in all
fields. Companies try to reduce their costs by cutting back on the expenditure
related to employment (reducing maintenance and operating requirements) and
electricity, and reducing floor space and amount of physical hardware devices.
The energy costs can be significantly decreased by applying virtualization
technologies on several fields (for example, remotely accessible monitoring and
management systems, server consolidation, cooling power). Impact on the
infrastructure: High-density devices require unconventional cooling, and
infrastructure devices have to be well manageable.
Infrastructure challenges: High-density servers can generate high heat load on
a much smaller place, compared to equipment manufactured a few years ago. In
addition, virtualization technologies increase the average capacity utilization
5 or 6-fold. In an environment like this, cooling problems arise much earlier
than power supply problems. The challenges of high-density cooling include
separation of cool and warm air, increasing the efficiency of cooling, ensuring
heat removal and possibilities for comprehensive manageability and predictive
troubleshooting.
"Legacy systems work fine for brute-force cooling the entire room, but
skyrocketing energy costs make them fiscally irresponsible and their
fundamentally oversized design makes them incapable of meeting today's
high-density challenges. Even worse, power and cooling waste may actually
prevent you from purchasing much-needed new IT equipment. Simple problem -
simple solution: Cut your power and cooling costs and use the savings to buy
the IT equipment you need," concludes Bertrand.
