Q. How do Solaris Containers compare with VMware ?
Posted by : Anonymous | | Published in
Consolidating with Solaris Containers:
Solaris Containers combine operating system partitioning with fine-grained resource controls to allow servers to be partitioned at sub-CPU granularity without having to replicate the operating system image itself. They provide a virtualised Solaris 10 Operating System image including a unique root file system, a shared read-only set of system executables and libraries, and whatever resources the root administrator assigns to the container at creation time. Solaris containers can be booted and shut down just like any instance of the Solaris 10 OS, and rebooted in seconds if the need arises. Unlike virtual machines, which must intercept every single interrupt and allocate it to the right instance, Solaris Containers support mainframe-level partitioning capabilities with almost zero overhead.
Consolidating using VMware ESX Server :
When an IT organization wishes to consolidate multiple Linux applications, multiple Microsoft Windows applications, Solaris OS applications, or a combination of them all, ESX Server is the consolidation option of choice. Not only can its virtual machine technology support all operating systems, it can support multiple versions of each one as well. IT organizations consolidating onto Sun x64 servers running ESX Server have the additional benefit of migration software that helps to package up an entire environment so that it can be installed in its own virtual machine.
For a more detailed description of the consolidation options available, please see the brief paper Consolidation through Virtualization

Q. What is eco-responsible computing ?
Posted by : Anonymous | | Published in
In an era, where most processors use 150 watts, each SPARC-based CoolThread processor uses less than half the energy of Intel Xeon or IBM Power processors at just 70 watts - consumption closer to that of many household light bulbs. This new processor offers unparalleled transactional throughput and is designed to save customers millions of dollars on skyrocketing datacentre power, cooling and space costs.
The impact on our environment is real: If half of the entry servers sold in the last three years were replaced with UltraSPARC T1 processors, over 11 million tons of CO2 emissions, or the equivalent of that emitted by about 1,000,000 SUVs, would be eliminated each year.

Q. How do I use the RAID controller on a SunFire V440?
Posted by : Anonymous | 18 November, 2005 | Published in
The SunFire V440 server has an onboard RAID controller that supports RAID 1 (mirroring) for the internal disks. If you want to do anything other than mirroring then take a look at Solaris Volume Manager (aka DiskSuite).
To use the RAID controller, use the command raidctl command.
raidctl -c disk1 disk2
raidctl -d disk1
raidctl [-f] -F filenamecontroller…
raidctl -l [controller…]

Q. What is CMT?
Posted by : Anonymous | | Published in
We know that a doubling of processor speed (frequency) does not result in a doubling of system performance. Why? Beacause improvements in memory latency have not kept pace with improvements in processor speed - in fact processor speeds are doubling every 2 years but memory speeds are doubling only every 6 years or so.
Throughput is impacted by both processor and memory speed; Sun recognised that having multiple threads in a processor could allow for greater throughput - as one thread is waiting for RAM, a second thread could execute and thus the waiting for RAM downtime is productive.
CMT - Chip Multi Threading allows for thread level parallelism to achiece unparalled scalability... within a chip.
Sun's CoolThreads technology, just announed this month, combines chip multi-processing (upto 8 cores per processor) and hardware muti-threading (upto 4 threads per core) . This is SMP on a single chip.
For more on this, please read this whitepaper - it's good!
