If you are looking to buy servers, we offer great deals & discounts on Rack Server and Tower Server. A Rack Server, also known as a rock-mounted server, is basically a computer rendered to use as a server and designed to be installed in a framework called rock. A Tower Server is a computer dedicated to use as a server and built in an upright cabinet that stands alone. If you have a brand & price in mind, SME Sauda has a deal just to match your requirement.

1. What is the difference between rack and tower server?

Tower servers have a shape similar to PCs and essentially powerful computers enclosed in a vertical cabinet.   Rack servers in contrast are horizontal, flat and mounted in slots of a rack.  Their advantages over a tower server include lower space requirement, simpler cabling, and lower noise during operation, use of a common cooling system for multiple servers and higher scalability.  Their disadvantages over a tower server include higher heat generated per server due to compressed form factor and price. Rack servers are significantly more expensive than tower servers.

2. Should I use a rack server or tower server?

Small medium enterprises can use tower server for their office LAN server.  They are cheaper and generate lesser heat than rack servers. Rack servers are typically used by large organizations and datacenters as these organizations need multiple servers in a single location.

3. What does a hot-plugged server mean?

In hot-plugged servers, devices such as Hard Disks drives can be removed and added in the server while the server is operational.  The server’s operating system automatically detects the change.   This is a critical feature when an organization cannot afford to have significant server downtime.  E.g. include mail servers, web servers, critical application servers and of course datacenters. However, in many small medium offices, where servers are used only for internal purposes (file sharing, running internal applications), a server without hot-plug feature can also be taken.  Hot-Plug servers are significantly more expensive than non hot-plug servers of a similar configuration.  Hot Swapping is used interchangeably with hot-plugged.

4. What is a dual socket server?

A dual socket server essentially refers to a dual socket motherboard.  The motherboard in such servers has two sockets allowing for two CPUs to use a common motherboard simultaneously.  This increases the processing power of server vastly compared to a single socket server (The power is not doubled but a 50-60% increase in processing power is seen).  Dual socket server are used in servers whose applications require high processing power like a high traffic web-server, ecommerce server, servers streaming video/music etc.  However Dual socket servers typically consume significantly more power and may not have standard motherboard sizes (hence choosing the right tower is important).  Most small medium offices do not need a dual socket server.  The additional socket in the motherboard also causes space constraints in the mother board, thereby reducing the flexibility to add other parts in the motherboard

5. What does a quad-core processor server mean?

A quad-core server refers to the number of cores in the processor.   Dual-core means two cores, quad-core means four, hexa core means six cores.  In essence a quad-core processor means four CPUs in a chip.  This is different from dual socket server (refer above).    Quad-Core servers have become popular for their high processing power compared to single core.  A Quad-core server is highly recommended for a reasonable sized office even though the computing needs may not be very high.   

6. What does a redundant power supply server feature do?

A server with a redundant power supply feature has two power units in the server.  Both power units can run the server, though they only operate on standalone basis (only one power supply at a time). This feature is used for high end servers or servers used in critical applications to build additional redundancy in the system.  If one power supply unit fails, the other takes over.  In areas with high electricity fluctuations, it is recommended that at least one power unit be connected with back-up power.

7. What does RAID Levels mean?

RAID stands for Redundant Array of Independent Disks.  The RAID Levels refer to different configurations through which data is stored, mirrored and read across different disks.  These configurations determine the suitability of existing data structure for redundancy and performance.  A detailed description of RAID Levels is outside the scope of this section.  A simple guideline will be as follows RAID 1 level servers provide excellent redundancy and good performance but are expensive (as all the data blocks are mirrored in an alternate drive).  A  RAID 5 level server provides good redundancy and good performance at a lower cost.  

8. What are the popular brands in servers?

The most popular server brands (based on orders and enquiries) in our website are IBM, HP and Dell.  All the brands offer multiple options across different price points to meet the technical requirements of different customers.  

9. How is the post sales service handled?

All the servers sold by us are covered under 1/3 years onsite warranty cover provided by the respective brands.  The after-sale customer service and support are handled by the manufacturers directly.
