| Density VS 1U/2U Rackmount
Servers If you are considering 1U/2U
servers, that’s GREAT!!! That means you
probably need to conserve space, have a
requirement for multiple rackmounted servers,
need to manage your servers, and are concerned
with maintaining server availability. Cubix has
the perfect system for you! Cubix’s Density
Series offers you features such as n+1 power,
less than 1U per server, redundant cooling fans,
environmental alarms, and remote management that
the competition either does not offer or charges
a premium for. Cubix integrates these features
into the Density system for a price that beats
the competition.
Deploying
Multiple Servers and Cubix
When deploying
multiple servers in a 19" rack, many
considerations must be made beyond the processor,
RAM, and hard drive configuration of the servers.
For instance, how much power is available to the
rack? How much power does the rack full of
servers require? How large of a UPS system is
required? How will you physically manage and
connect 42 power cables for a fully loaded rack
of 1U servers? Does the server fail if a power
supply fails? How will you know one has
failed? What is the procedure for resolving the
problem?
Cubix’s
Density system helps ease the problems of
deploying multiple servers. For instance, a fully
loaded Density system with 8 server blades
requires no more than 650Watts of power. Compare
that with 1U servers. The smallest 1U server has
a 150Watt power supply and most 2U have
200-300Watt power supplies. Therefore a
comparable number of 1U servers equals 1200Watts
of power. Cubix’s power system is nearly
twice as efficient. This also means less heat is
generated, UPS requirements are smaller, and
energy costs are reduced.
Each of the three
hot-swappable, load sharing, n+1 power supplies
has its own cable so each supply can be sourced
from a different power circuit. Should a power
failure occur on one circuit, the other two
continue to keep the system operational.
Additionally, that means there are only three
power cables for each chassis. Therefore, a fully
loaded 47U rack containing six Density chassis
has only 18 power cords. Contrast this with 47
power cables for a comparable number of 1U
servers. That also means power strips will have
to be added to the cost of your server
installation. But if your power strip fails or a
1U power supply fails, you lose server
availability. Cubix provides you with load
sharing supplies, fault-tolerant cabling
capabilities, hot-swap serviceability, and
audible and visual alarms.
