|  |  Lower costs, accommodating considerable storage capacity growth and realizing the highest possible level of data availability were the most important reasons the M+ Group decided to implement a Storage Area Network (SAN). Moreover, purchasing a SAN made it possible to centralize storage capacity, thus limiting the number of servers.

The M+ Group offers channel management solutions and services. "We
specialize in creating good contacts between customers and their target
groups at the individual (customer) level," explains director Mato
Bozic. "Our channel management solutions and services enable customers
to communicate completely independent of the channel used."
We help customers choose the most effective channels for approaching
the desired target group. We have our own software development
department and can build tailor made (web-based) applications if the
situation demands it. And we can handle all the concrete communication
activities from beginning to end." From execution to fulfillment and
analysis: M+ monitors and manages the whole process. Transparency and
measurability are important focal points, both during and after the
specific communication activities. The principle is to always be able
to demonstrate the effectiveness per available channel, based on the
customer’s budget. "The company works for some five hundred customers,
including well-known firms such as Allianz, Durion, Stroeve Vermogens
Beheer (Asset management), Interpay, Jaguar, Zwitserleven (Insurance),
Nestle and Volvo."
'Time to market'
One of the problems facing M+ was the fast-growing need for storage
capacity: frequently as much as 70 per cent per year. This meant that
more and more servers had to be purchased. At that time, the company
was still using a traditional DAS (direct attached storage) approach,
where each server had its own storage capacity. That caused numerous
problems, for example the fact that the number of servers in which the
company had to invest grew dramatically, but the available storage
capacity was not only difficult to manage; it could not be optimally
utilized, either.
"We asked COMPAREX to cope up with a solution for this problem," Bozic
relates. COMPAREX’ proposal involved implementing a Storage Area
Network (SAN). Such a storage approach offers M+ many advantages. For
example, centralizing the storage means that storage capacity can be
allocated both quickly and simply, without having to continually
purchase new servers. Should it be necessary to add new server systems,
this can be done quite simply. In other words: the 'time to market',
which is so important for a company like M+, can be considerably
reduced.
Price/performance ratio
In addition, the available storage capacity can be deployed much more
efficiently and a SAN offers high availability levels. Moreover, a SAN
offers interesting possibilities for utilizing different types of
storage. This means that the appropriate storage systems can be
selected based on the sort of information system and the type of data
to be stored. The consequence? An optimum price/performance ratio per
application or per type of data being stored.
The solution that COMPAREX has developed consists of an IBM FAStT600
Storage Area Network in which twelve disk systems are used, each with a
capacity of 73 Gigabytes. The M+ servers are linked to the SAN via two
Cisco iSCSI Storage Routers. These routers make it possible to utilize
the quality and the possibilities of a SAN based on Fiber Channel, but
at the much lower costs of an IP network. In addition, an Ultrium Tape
Library has been installed that is constructed around an LTO tape
drive. IBM Tivoli software has been purchased to make the backups. In
addition, COMPAREX has also delivered M+ six IBM servers from the
X-Series 335 and 345.
Flexible and attractively priced
This solution satisfies the requirements M+ specified for the new
storage infrastructure. The company wanted a flexible storage solution,
so that unused storage capacity can be allocated to servers or
applications quickly and easily. The scalability of the solution
delivered is also important to M+. It must be easy to expand the
central storage, given the company’s rapidly growing demand for storage
capacity. Availability also played an important role in M+’s decision
to go ahead with COMPAREX’ solution. "Some customers have their entire
projects databases on the SAN," Bozic explains. So we cannot afford to
be down for even a day. Because the storage is set up using a redundant
hardware configuration, the SAN’s availability level is extremely high.
If a component fails, all the data is still available for all the
servers linked to the SAN.
"Costs also played an important role for us," Bozic goes on. "By using
the Cisco SN5428-2 iSCSI Storage Routers in combination with the IBM
FAStT600 storage systems based on Fiber Channel, M+ now can now use an
FC-SAN at the cost of a solution based on IP."
