What's the difference between SCSI and EIDE?

The primary difference is that SCSI (Small Computer System Interface) has a processor built into the drive which allows for faster read / writes and is generally much more reliable. The EIDE (Enhanced IDE) drives rely on the system CPU.

What's Name Based Hosting?

Name Based hosting allows you to serve multiple virtual domains from a single IP address. Name based hosting does not affect the performance or appearance of the domains hosted.

The advantage of using Name Based hosting is that it is much easier to administer a single IP address. It also means that the number of sites you host is not limited by the number of IPs you have available.

There are two limitations on name based sites:

1. Each name based domain can have only 1 Telnet/FTP, but an unlimited number of pops are available.
2. Name based domains can not have their own SSL certificate (it would need to be shared).

What's the difference between DBS and DwRS?

DBS

• Single IP dedicated servers.
• Designed for small to medium sized companies, or large enterprises looking to host their business web site, intranet and extranet, or highly integrated e-commerce store.
• Entire dedicated server.
• Three levels of control.

DwRS

• Designed for established web hosting companies that have multiple domains.
• Capability to host IP based as well as name-based domains.
• End-user web-based Technical Support Services for as low as US$ 0.60/domain/month.
• Ability to configure plans through templates.
• Entire dedicated server.
• Three levels of control.

What's the difference between IP and name-based hosting?

IP Based

• Each domain has its own unique IP number.
• Domains have access to multiple Telnet/FTP Accounts.
• Ability to register a domain-specific secure certificate.

Name-Based

• Multiple domains share the same IP number.
• Domains have access to ONE Telnet/FTP account, the balance are all POP accounts.
• Inability to register a domain-specific secure certificate.

Will there be a statistics program installed on my server?

Yes. The Dedicated Servers have access to Analog Stats, a graphical stats program.

What's a DNS/BIND Name Server?

A Name Server is a computer that maintains a database of domain names and their corresponding IP addresses. The domain name system (DNS) is the way that Internet domain names are located and translated into Internet Protocol (IP) addresses. It has name resolution software that translates domain names into IP addresses, and vice versa. Because domain names are alphabetic, a DNS must translate the name into the corresponding numeric IP addresses for the Internet.

BIND - stands for "Berkeley Internet Name Daemon", and is the Internet de-facto standard program for turning host names into IP addresses. The BIND DNS Server is used on the vast majority of name serving machines on the Internet, providing a robust and stable architecture on top of which an organization's naming architecture can be built. The resolver library included in the BIND distribution provides the standard Application Programming Interfaces (APIs) for translation between domain names and Internet (IP) addresses and is intended to be linked with applications requiring name service.

What are the benefits of having my own DNS/Bind Name Server?

• Complete control over domains.
• Ability to park domains without an additional fee.
• Ability to make MX record changes without an additional fee.
• Real name servers provide greater anonymity.
• Through our Bind/DNS software, you have access to an intuitive web-based interface to make any changes/modifications.

Can the myTuffy.Net logo on the control panels be removed or replaced?

Yes. In the Appliance Administrator for the DwRS and the Private Server Administrator for the DBS, you can replace the myTuffy.Net logo with your company logo so as to brand/private label the control panels. When logged in through Telnet, use this path to make the changes: /usr/lib/opcenter/images/logo.gif

Can I add my own software?

Yes. You have root access and hence the ability to add any software required to operate/enhance your business.

Will I have root access with DBS and DwRS?

Yes, you have full root access to your Dedicated Server.

Can I share one (1) secure certificate with all my clients on my DwRS?

Yes, for US$ 99.95 we can configure your DwRS to use a shared certificate.

What does unlimited domains mean on the DwRS?

Under the DwRS, customers have the ability to host between 50 and 800 IP based domains depending on the plan chosen, and an unlimited number of name-based domains, restricted only by the server capacity and resources.

What kind of network cards are being used?

Every server has dual 10/100 3Com NIC ports.

What kind of hard drives are used in the servers?

Every server consists of hot swappable Seagate or IBM SCSI Ultra-3 (Ultra160/m) 10,000 RPM (Revolutions per Minute) hard drives.

What's SCSI?

SCSI (pronounced SKUH-zee), the Small Computer System Interface, is a set of evolving American National Standards Interface (ANSI) standard electronic interfaces that allow personal computers to communicate with peripheral hardware such as disk drives, tape drives, CD-ROM drives, printers and scanners faster and more flexibly than previous interfaces. Originally developed at Apple Computer, the present set of SCSIs are defined for parallel interfaces.

The latest SCSI standard is Ultra-3 (sometimes spelled "Ultra3"), which increases the maximum burst rate from 80 Mbps to 160 Mbps by being able to operate at the full clock rate rather than the half-clock rate of Ultra-2. The standard is also sometimes referred to as Ultra160/m. Disk drives supporting Ultra160/m offer much faster data transfer rates. Ultra160/m also includes cyclical redundancy checking (CRC) for ensuring the integrity of transferred data and domain validation for testing the SCSI network.

In addition to faster data rates, SCSI is more flexible than earlier parallel data transfer interfaces. The latest SCSI standard, Ultra-2 SCSI for a 16-bit bus can transfer data at up to 80 megabytes per second (Mbps). SCSI allows up to 7 or 15 devices (depending on the bus width) to be connected to a single SCSI port in daisy-chained fashion. This allows one circuit board or card to accommodate all the peripherals, rather than having a separate card for each device, making it an ideal interface for use with portable and notebook computers. A single host adapter, in the form of a PC Card, can serve as a SCSI interface for a laptop, freeing up the parallel and serial ports for use with an external modem and printer while allowing other devices to be used in addition.

What's EIDE?

Enhanced Integrated Drive Electronics - Enhanced (sometimes "Expanded") IDE is a standard electronic interface between your computer and its mass storage drives. EIDE's enhancements to Integrated Drive Electronics make it possible to address a hard disk larger than 528 Mbytes. EIDE also provides faster access to the hard drive, support for Direct Memory Access and support for additional drives, including CD-ROM and tape devices through the AT Attachment Packet Interface.

What's RAID1?

RAID Level 1 (RAID1) means that one drive mirrors the other. In the event that one of your drives fails, the other will immediately continue to serve data. An additional feature with RAID is that, if one drive is overtaxed, the overflow requests will be handled by the second drive. RAID1 requires two drives, only one of which you can use.

What's RAID5?

RAID Level 5 (RAID5) distributes the parity among the drives. This can speed small writes in multiprocessing systems, since the parity disk does not become a bottleneck. Because parity data must be skipped on each drive during reads, however, the performance for reads tends to be considerably lower. RAID Level 5 is n-1 meaning you lose the disk space of one drive in order to stripe data across the drives. A minimum of three drives is required for RAID5.
