Using computers and information technology (IT) in general comes at a great price. It may consume electricity, human power, or intellectual curiosity. To become good at using something, usually takes many repeat failures and certainly many hours of study and operation.

In the IT space, just two major companies control the worldwide computer desktop: Microsoft with it’s Windows operating system, and second runner up Apple Computer with Mac OS X. Sure, niche players like Sun Microsystems Solaris, Red Hat Linux, or SUSE Linux are available, but are not being distributed on millions of desktops every fiscal quarter. So far there have been at least six releases of Windows counting all the way back from Windows NT, Windows 95, Windows 98, Windows ME, Windows 2000, and Windows XP. Microsoft recently announced Windows Vista, to be released sometime in early 2007. All of these operating systems has evolved from the earlier release, and as the adoption rate increased worldwide, so did the various problems.

Apple Computer has released five Mac OS X products: Mac OS X Cheetah, Mac OS X Puma, Mac OS X Jaguar, Mac OS X Panther, and Mac OS X Tiger. Apple recently announced Mac OS X Leopard, to be releases sometime in future, probably in mid 2007. In the early days of desktop computing, there was a rapid one-upping, as each company bundled features, services, and support to hold parity. Prior to Mac OS X, under the Mac OS Classic environment (i.e., Mac OS 8 or Mac OS 9) there was competition, but with the release of Mac OS X, and especially after Mac OS X Jaguar, Apple pulled ahead and had never looked back.

The investment in Mac OS X is paying off now, as very high level support is now included in the operating system for OpenGL, content creation, and visualization unheard of in previous releases.

With added services also came added security. There is not a single instance of a Mac OS X virus released in the wild to take down Mac machines. On the Windows platform, it’s a regular spectator sport to see how many machine go down on a weekly basis due to spyware, malware, and computer viruses.

Operating system viruses and spyware cripple machines on the Windows side consistently. Antivirus and antispyware tools are not just available, but essential subscription based software to get the machines up and running on a daily basis. In a hypothetical scenario (actual hardware prices are today very competitively priced when performance is compared, i.e., oranges to oranges), if a company saves 10% to 20% on the initial purchase of commodity x86 hardware (or AMD), capable of running Microsoft Windows software, and in the course of the machines life gets hit not by one virus, but by multiple viruses, how much money was actually saved? It may be that the liabilities associated with the commodity hardware and a ubiquitous operating system like Windows actually cost 50% more than a Apple Power Mac G5 or iMac G5 networked system, when the cost of virus software, added security programs, salaries of MCSE technicians and engineers, and the regular system corruptions due to hackers and virus authors are taken into account.

There’s been a dream of mine to have multiple cheap machines networked in a way to form a hive mind, so commands on one distribute to all and work together. This is loosely called grid computing. Imagine 3 iMac G5′s, Power Mac G5′s, or PowerBook G4′s networked together to work as one. The future is now!

At NAB 2005, Apple announced Final Cut Studio, which allows distributed Compressor rendering/encoding, so through a dedicated gigabit ethernet or firewire infrastructure, you combine a few machines into a working super computer. Mac OS X Tiger has as it’s base a technology called Xgrid, which is a protocol for clustering machines together out of the box.

The secret to success is the gigabit ethernet connection running at 1 Gbps or 128 MB/s. so now in the new computing model, the CPU comes second to the network connection. In a few years 10 gigabit will be standard, passing 2 Gbps or 4 Gbps fibre channel.

So now that you can grid the machine together, how about storage? Apple has an Xsan solution. Xsan costs just below $1500 a workstation to get the computers to share storage ($999 Xsan seat license, $499 fibre channel PCI-X card). A much more elegant and economical solution, that works on panther 10.3.5 and above is iSCSI.

you remember SCSI? all macs had it before ATA. Storage engineers never gave up on SCSI, and are reintroducing the SCSI protocols, but over gigabit ethernet! On a more modern mac, you already have the port, or can easily get a $20 network PCI card (recommended approach to separate the storage network from the IP network). The beauty of iSCSI it can be entirely software based, so yes you get a performance hit, but imagine sharing all your hard drive on a small gigabit network using software SAN. This is revolutionary. Current vendors that support the Mac are ATTO technology and Studio Network Solutions. These companies are just the beginning to a wonderful marriage of storage, grid computing, and the Mac.

Apple is moving the Mac to an Intel chipset. Until that day in 2007, where all new Mac machines will be Intel inside, expect many surprises. The glue to any good chipset deployment is not only the underlying semiconductor design, but the application environment to write to the hardware, or application program interface (API). Apple Xcode is the technology that drives the software engine. When the multicore comes out with hyperthreading, then we’re talking a good move toward Intel. The chip will have at least two onboard processors, and two virtual processors. All eyes are watching the Intel Fall Developer Forum, to see the processor roadmap.

Along with advanced processors, comes 64-bit computing, which allows access to more than 4 GB of RAM (the 32-bit limit). Today’s Power Macs can hold 8 GB of RAM. I was told by Adobe, that Creative Suite 2 needs around 2 GB of RAM for all it’s applications, and Apple Motion definitely needs all it can get (4 GB at least). the future is always in flux.

At the end of spring and now into the summer, the GPU market has reached an inflection point. Unlike the 90 nm and 65 nm semiconductor barrier, both NVIDIA and ATI chug along with product announcements and advancements. ATI announced at Computex CrossFire, a method to bond multiple PCI/AGP video cards together for near double the performance. NVIDIA had already announced a similar solution they called SLI. NVIDIA stirred the pot again with the GeForce 7 series. if the GeForce 6 series did not scream enough, we have the latest and greatest with more transistors and higher performance.

NVIDIA spurs on interest in its product and introductions with unique characters, usually buxom women scantily clad to attract the gamers and young folk of the planet. if you recall NVIDIA creates these female persona to demonstrate the real time rendering of characters in cinematic motion. all in all we have luna, nalu, dusk, and dawn (summary below). Will these chipsets make it the Mac?

Almost since the beginning of desktop computing, the ability to share has been essential. Flash forward 30 years, and not only are computers networked, behold the pervasiveness of the internet to every workstation and laptop, but soon every computer will have shared storage. The simplest form of sharing would be networked attached storage (NAS), where you use built in networking protocols (TCP/IP, SAMBA, NFS, AppleTalk, etc.) to mount a remote volume over the internet or over a local area network (LAN) to a client system. You can now parcel files, using the file sharing aspects of the operating system.

A more robust system in the NAS space, uses an intelligent controller, or server (Mac OS X Server, NAS head, etc.) to deliver storage connectivity.

Companies like NetApp and BlueArc have mastered the front end of the storage array, and allow on the fly configuration, modeling, and allocation of storage resources as the needs of the enterprise change. Certain applications, like databases, require block level access to storage devices, as if they were directly attached to an individual computer. Application performance may suffer if the program is looking for block level access, but only sees NAS, however, in general, NAS is fast and is a completely viable storage platform.

Be it a NAS environment or a storage area network (SAN), most likely SAN is the storage subsystem architecture anyway. Currently there are three ways to attach a SAN to a workstation or workgroup:

Fibre Channel
Gigabit Ethernet, GbE (iSCSI)
IEEE 1394a or 1394b (FireWire)

Each methodology has is benefits and pitfalls, but all offer rugged access to shared storage resources. With a shared storage solution, the workstation can boot from the SAN, share files and applications (if the software licensing agreement allows it), and make the backup and restore aspect of data management easier.

Cloak Media offers many services, and simple Windows XP integration (setting up a printer, networking, shared storage, etc.) into the Mac OS X environment is one of them. I know there are certain vertical applications that only run on Windows XP or Windows 98. On the Mac, Microsoft has VirtualPC, but it does not operate as fast as a true PC, since every service needs to be emulated. There is nothing like using an actual PC, but also expect the standard PC headaches, like viruses, spyware, malware, and regular instability.

I choose to concentrate on Apple Mac technologies. You can focus on what’s important, the applications and the workflow, not trying to get a square peg into a round whole, as is often the case on commodity hardware from the traditional Windows/Intel (Wintel) world (looking for drivers, registry fixes, scan disk, etc.). It’s worth a little more money upfront to get a system that works out of the box, without a lot of futzing, and that’s why Cloak Media works primarily with Mac OS X and Mac OS X Server.

Likewise, support costs are dramatically reduced on the Mac, since it does not break as often. In the history of Mac OS X, there has not been a single virus in the wild, but only theoretical attacks.
