Testimonials
Contact data of the referrers will be happily provided on request

   1) (telecommunication enterprise, approx. 1000 emp.)

Mr. Erasmi has been working for several years as a consultant for our company, both
project-oriented in various complex design and migration projects in a highly
productive environment and in long-term know-how transfer in Solaris, cluster,
virtualization, automation and storage / SAN.

In addition, he also developed concepts, among others in the area of disaster
recovery, backup, control, centralized administration, IT security, in particular,
system hardening, performance management and more.
Due to his strong technical expertise and his excellent team skills, he has
integrated quickly into our team and our processes. His teammates and colleagues
appreciate him as an extremely competent, reliable and at the same time friendly
and helpful colleague. Despite his role as an external consultant, he is, from the
management perspective, a fully integrated, loyal team member. His work is always
exemplary structured, well documented and traceable.
He does not lose, nor in unexpected situations, nor operating in projects with high
technological complexity, the sight of the big and important business needs. The
consideration of cost is one of its assessment criteria for a solution.

Mr. Erasmi brought in the entire time working for our company in numerous customer
environments, his experience gained in terms of technology, process and cost
optimization. The confidentiality requirements of his customers were always
respected. Through his assistance we were able to increase the maturity of the data
center operations, and he clearly made a substantial contribution to the service
level improvement, cost reduction and certification achievements, such as SOX
compliance.

The use of Mr. Erasmi has up to date always made sense from an economic point of
view. His expertise would have been to build in-house at a reasonable cost only in
exceptional cases.

I can recommend Mr. Erasmi with conviction.

   2) (IT service provider for aerospace, approx. 3000 emp.)

Mr. Erasmi supported us in building a service area with SUN Sf20k, T2000, Solaris,
a large number of zones (> 90), Oracle databases and applications running on
Veritas Cluster Server, Veritas Volume Manager, SAN, Hitachi HDS 9990, Oracle and
SamFS.

In addition, he created several concepts for the construction, operation and
verification of the surrounding components and conducted staff training. He has
extensive expertise and knows to provide it with great team spirit and friendly
style very well and always communicate to our complete satisfaction into technical
solutions. Even outside regular operating times for us, he was always approachable
and responded to inquiries always timely.

His dynamic approach to the challenges encountered were very helpful to us to
complete the project successfully within the tight time frame given.

I would appreciate any time to work again with Mr. Erasmi.



   3)   (Sun Microsystems GmbH, Professional Services, IT service provider)

Wolfgang Erasmi has supported me during my time at Sun Microsystems Inc. for more
than a decade as an external consultant in a variety of consulting projects and
long-term support to our customers.

His main application is highly available Unix (primarily Solaris) / storage on the
SAN and NAS environments, both in system integration and planning, as well as the
operation of the systems. Mr. Erasmi has created for our customers technically
perfect documentation and was also assigned as a coach for in-house training.

Mr. Erasmi is a very dedicated employee who has supported us and our customers at
all times with high motivation and his excellent skills in consistent high quality
and quantity.

Because of his personal and professional competence, he was by our customers - and
is one of mine - very valued colleague and business partner, whom I continue to
recommend you and with whom I would always work together again.

I am grateful for the many years of cooperation!
