Blade Computing - CPU Density vs Memory Density

While there are competitive products that have a better Core density within one Rack than our Constellation System, there is simply no blade solution that can compete with our blade memory density.

The question here realy is, what is the best combination! This leads me back to the question, why blades? One of the main reasons why customers choose the blade technology is:
  • VIRTUALIZATION
  • DENSITY
  • POWEREFFICIENT COMPUTING
I am sure that you will agree with me that a combination of 8 Cores together with max 16GB RAM isn't realy the way to run a virtualized infrastructure, right?

So, let's look at the solutions and most innovative Sun Blades we have available at the moment!

Sun Blade T6320 UltraSparc T2 Single Socket Server Module
  • 1x 8 Core UltraSparc T2 CPU
  • 16x Dimm Slots = 64 GB Fully Buffered DDR2 Memory (with 4GB Dimms)
Sun Blade X6220 AMD Opteron Dual Socket Server Module
  • 2x 4 Core AMD Opteron CPUs
  • 16x Dimm Slots = 64 GB ECC DDR2 Memory (with 4GB Dimms)
Sun Blade X6250 Intel Xeon Dual Socket Server Module
  • 2x 4 Core Intel Xeon CPUs
  • 16x Dimm Slots = 64 GB FBDIMM Memory (with 4GB Dimms)
Sun Blade X6450 Intel Xeon Quad Socket Server Module
  • 4x 4 Core Intel Xeon CPUs
  • 24x Dimm Slots = 96 GB DDR2 FBDIMM Memory (with 4GB Dimms)
Please keep in mind that all of those Blades fit into the very same Sun Blade 6000 Chassis or the Sun Blade 6048 Constellation Chassis and share the same unique management interfaces.

To summ up the calculations:
One Constellation Rack in combination with the Sun Blade X6450 provides 768 Cores and 4.608 TB RAM. This are 6GB RAM per Core!

Do you need more RAM per core?
One constellation Rack in combination with the Sun Blade X6250 or X6220 provides 384 Cores and 3.072 TB RAM. This are 8GB RAM per Core!

Do you need Sparc Technology?
One Constellation Rack in combination with the Sun Blade T6320 provides 384 Cores and 3.072 TB RAM. This are also 8GB RAM per Core! Now as we talk about CMT - Chip Multi Threading, this would be 1GB per Thread. Also very interesting is the power consumption for this UltraSparc T2 Blade Solution!

Summary, we can deliver an intelligent Blade Design with the right CPU/RAM combination, and this within the single and standardized Sun Blade 6000 Enclosure.
