dear sir, madam,

we are investigating different options that exist to run a relatively
small 'big data' infrastructure for our customer, and are looking
currently at the Stratio-platform offering .
The total amount of data that we need to process is roughly 5 TB.
We have budget for 6 servers, each with 16 dual-thread cores and 128 GB
of RAM.

To be sure that your solution can be implemented within the restrictions
of our customer's budget, security policies, and IT-departmental
policies, we have the following questions:

• the different server types:
  You mention a "Stratio Manager" and a "Stratio Node" as server roles.
  The buget of our customer allows a maximum of 6 physical machines,
  installed in two datacenters (3 servers in one, 3 servers in the other
  datacenter).
  When we would need to allocate one of these 6 physical machines as a
  "Stratio Manager" role only, then we loose a lot of compute power for
  this node role alone.
  -> is it possible to combine a "Stratio Manager" on the same physical
  machine as a "Stratio Node" ?
• alternatively, would it be possible to run the "Stratio Manager" on a
  VMware virtual machine ?
• does the "Stratio Manager" require internet access to download your
  software packages? This company (like many others) has tight
  restrictions on which machine can access the internet : it will be only
  granted via a proxy server. So would the installation script be capable
  to work with a proxy server? Can it be specified on the command-line
  which proxy server, and which credentials on that proxy server need to
  be used to access the internet ?
• is the "Stratio Manager" required to run after the installation has
  been completed? In other words, what if the machine where this "Stratio
  Manager" is installed, goes broke? Is it a Single-Point-Of-Failure to
  continue running with the "Stratio" suite of software ? What activities
  cannot be done anymore with the "Stratio Nodes" when this manager is
  unavailable ?
• the installation is done with superuser ("root") privileges, obviously
  because it is installing packages and thus modifying the operating
  system as it comes pre-installed by our IT department. They want
  obviously to know what changes will be done on the operating system by
  this Stratio installation :
  packages that will be installed
  any kernel modules that will be added ?
  any operating system configuration files that would be modified
  (crontabs, user accounts, device files, driver configs, ...)
• does any part of the "Stratio" platform require to run with superuser
  privileges, after the installation is completed ? If so, please provide
  details.
• we desire geo-redundancy of our servers : one set of 3 servers running
  in one datacenter, another set of 3 servers running in another
  datacenter.
  Can these 6 servers work together as a pool to join forces ?
  What happens if an entire datacenter is lost (how is data replicated,
  which activities are no longer possible)?
  Can the servers of one datacenter be un-configured (removed) from the
  'pool' so that we can re-install them with some other configuration that
  we want to evaluate ?
• in your installation requirements, we read that the machines must be
  RHEL 6.5 or 6.6 ; in this company, they run standard RHEL version 6.7
  -> is this version RHEL 6.7 supported by Stratio ?

Many thanks in advance for your swift replies ! Please reply on each
question, feel free to redirect us for each individual question to
detailed (not generic) answers somewhere on the web.
