Ahora, el enfoque que me gustar�a que tomen, es el siguiente. _Ninguna_ de las ventajas que se mencionan, son aplicables para linux. Ahora, porque linux en ves de w2k? Pd. Los quiero a todos incados cuando vean el quote de Dennis Ritchie que est� al final del mensaje. Ppd. Excepto el punto 11 en el cual linux le patea el culo a cualquiera. -- Alvaro Figueroa C. I'm the root Universidad Latina de CR and you're the hood Departamento de Computo I have other souls in my hands ---------- Forwarded message ---------- Date: Wed, 15 Aug 2001 00:05:49 +0530 From: Siddhartha Jain <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Why Solaris/Unix is better than Win2k Hi, I am not trying to start a flame war or an arguement. Actually, in the first ever flame war i got into i pieced together reasons why i thought Solaris was better than Win2K. Some were picked directly from Sun's site and others from my experience. Here is the list. Can you make additions to it? Please try not to make generalisations as it hard to defend them. I'll be glad to summarise. 1. Dynamic Domaining - Allows a Sun server to be partitioned into several independant virtual servers. The resources allocated to each domain can be dynamically changed as required without any downtime. 2. Dynamic Reconfiguration - Dynamic Reconfiguration (DR) provides operating system services that support hardware features for delivering increased system management and availability. It allows systems administrators to add, change, and remove system components without shutting down the system. Many mid-range to high-end SPARCT systems support a long list of hardware boards that can be changed without shutting down the system, including: memory and CPU boards, I/O controllers, network interface cards (NICs), disk drives, and other SCSI devices. In many cases, DR also supports multiple paths to one I/O controller or NIC. For such cases, Solaris software also supports dynamic load balancing and dynamic switching of paths. pbind - Allows a set of processes to be allocated to a set of processors. This means i can allocate the bulk of CPUs in my box to the CPU intensive processes and the I/O intensive processes can have the remaining CPUs. This eases scheduling load on the server. What about NT/2k? 3. Multipathing - Network interfaces can be grouped together to provide high-availability and redundancy. This means i get upto 800 Mbps bandwidth using 4x100 Mbps NICs on a single IP. Also, a NIC failure doesn't bring network down. What about NT/2k? 4. Up to 128 CPUs on a single system as against a mere 8 for a Win2k Datacentre server 5. Eight-node clusters as against four-node cluster limitation in Win2k Datacentre server 6. Up to 512 CPUs in a clustered environment as against just 32 CPUs for a Win2k Datacentre server 7. Security - Role based Access Control brings mainframe security to Solaris. This means there is no single super-user who can screw up everything. So the 'root' can do system maintenance but cannot peak into your companies valuable database content which can be only accessed by the DBA. 8. Hot pluggable system boards - System boards are boards with 4 CPUs, memory banks and PCI cards on each board. Any board can be replaced online in the event of a failure without rebooting the entire system. 9. A backplane bandwidth of 12.9 GB/sec. Can Wintel beat that? 10. Automated Dynamic Reconfiguration - Automated Dynamic Reconfiguration -- also known as Reconfiguration Coordination Manager (RCM) -- provides a scripting interface for DR events so that application programs such as database and system management tools can take predetermined actions when hardware configuration or operating system events occur. For example, additional CPUs and interface cards can be reconfigured for a database server backend when the response time falls below defined acceptable levels without operator intervention. 11. File System Logging - UNIX File System (UFS) logging is the process of storing transactions (changes that make up a complete file or directory operation) in a log before they are applied to the file system. Once a transaction is stored, the complete transaction can be applied or reapplied to the file system later. UFS logging offers two advantages. It prevents file systems from becoming inconsistent, therefore eliminating the need to run fsck. And, because fsck can be bypassed, UFS logging reduces the time required to reboot a system when it is stopped other than via an orderly shutdown. Also, look at www.netcraft.com. Amongst the 50 websites with the highest uptimes, only one runs on Win2k. The rest run some flavour of Unix. In the "Most requested websites in the last 30 days" only 12/50 run on WinNT/2k.
