From small companies to large enterprises, modern businesses run on information and most companies collect unique and valuable data such as customer and product databases, research and design (engineering) files, email, and office files that are critical to operations. Without continuous availability to this critical information the business cannot function.

The real problem today is that too many small to medium businesses do a poor job at protecting their data. Important files are either scattered all over the network or on a single server that has no real data protection. Fault tolerant RAID is a good starting point but the simple fact is that even a server with fault tolerant hard drives cannot protect data in all cases (a major server crash, for example, can corrupt data) and may lead to costly downtime. The best practice is to combine internal RAID arrays with removable or external backup options such as tape drives, backup servers, NAS devices, external storage enclosures, and so on.

An investment in data security will always payoff in the long run potentially saving thousands in lost downtime and productivity. True data protection mean continuity of business operations and is not about a single product but rather a strategy of combining the right product solutions and practices for a given organization. System integrators and resellers need to be aware of this and offer the best solutions to their customers.

NAS devices come in different forms such as "cube", tower, or rackmount and provide an easy way to add storage and backup capacity without needing to build and license a separate system. They connect to the network through standard RJ-45 cables and act as any network device plus will have some form of embedded operating system interface. NAS box itself often includes multiple hard drives that can be setup in a RAID for fault tolerance (RAID 1, 5) or RAID 0 for performance. NAS devices may be referred to as IP Storage appliances due to the fact the connect to your network using an IP address, unlike internal storage devices or direct attached storage devices that use USB, SCSI, etc, to connect to an existing system.

ASI offers small to medium business NAS devices from Infrant and Thecus and home office or small network devices such as the Western Digital NetCenter or Netgear's Storage Central.

SAS bandwidth is starting at 3GB per second speed and will eventual scale to 6 and 12 GB/sec for exceptional performance potential. SAS devices are just starting to make an appearance on the market so we offer an introduction here to how it works and what devices will be available.

Serial Attached SCSI is a point-to-point architecture, distinct from parallel technologies in which devices are connected using shared-access topologies such as a Fibre Channel arbitrated loop of the SCSI bus. It a serial, self-clocking, full bandwidth communication protocol with dedicated device bandwidth and the ability to combine port bandwidth.

SAS also uses a backplane that accommodates both SAS and SATA drives (though it is not recommended to mix them together), and you can cascade backplanes using edge expanders (expanders are needed to allow an HBA port to talk to more than one drive). Host bus adapters (HBAs) have access to all ports on an expander including other HBAs, allowing backplanes to be chained together for easier storage expansion.

Cabling requirements for the Serial Attached SCSI (SAS) interface are able to be met using thinner cables with smaller connectors. This permits improved routing, airflow and cooling within systems using the serial interface. As well, the electrical complications and cross talk usually associated with the larger parallel cabling are reduced. SAS technology permits universal connection between SATA and SAS drives to ease configuration and improve hot swap capability.

SAS Hard drives

There are both 3.5" and 2.5" SAS drives. The 2.5" drives offer lower power consumption (up to 30% less) and allow higher density storage applications critical for enterprise use. Supermicro is the first major server vendor to offer SAS based servers, mobile racks, and controllers and in partnership with Fujitsu. Fujitsu 3.5" SAS drives will start at 36.7 GB, 73.5GB and 147 GB capacities, while the 2.5" models will be launched at 36.7GB and 73.5GB and run at 10K RPM. Fujitsu SAS hard drives will be available from ASI through Supermicro, other brands should also be available in the near future as SA market grows.

Sony has a new generation of high performance AIT tape drives with enough models to fit any company's backup requirements. Sony AIT technology has many advantages over competing tape formats.

Chief among these advantages are:

Small Form Factor with High Capacity. The AIT format was developed to handle the capacity requirements of data-intensive applications in a compact 3.5-inch drive form factor, making it an efficient, cost effective storage solution that saves valuable IT real estate.

Helical-Scan Technology Increases Recording Density and Reliability. The Sony AIT drive
employs a helical-scan recording style in which data tracks are written at an angle relative to the edge of the tape. This provides higher density recording, enabling Sony customers to lower media expenditures and increase efficiency by storing more data on a smaller amount of tape. Helical-scan recording also reduces the need to rewind the tape cartridge as frequently, thus reducing wear-and-tear and increasing reliability.

Memory-in-Cassette (MIC) Architecture Enables Fast Access to Data. MIC technology puts information about the contents and capacity of the tape in a non-volatile memory chip embedded in the tape cassette itself. Using this information, the tape drive can position the tape at high speed to write or read data in an accelerated manner.

Advanced Metal Evaporated (AME) Media Provides Increased Reliability and Capacity. AME media represents the culmination of  over 50 years of Sony innovation and experience in magnetic tape technology. Supporting higher recording density than other types of tape media, AME also reduces buildup of debris and static electricity, further extending the useful life and reducing the chance of recording errors when using AIT tape.

Please refer to the following chart to compare models.

These Sony tape drives do not ship with tape backup software but you can purchase Veritas Backup Exec 10 software (see section below).

ASI is now offering Veritas (Symantec) Backup Exec^TM 10 as the choice for backup and recovery software. With multiple software agents and options available you can customize Backup Exec 10 to the needs of your company or expand in the future as required.

ASI SKU # 40094 = Veritas, Backup Exec 10 for Small Business Servers

VERITAS Backup Exec 10 for Windows Small Business Server is designed to deliver cost-effective, easy-to-use, and highly reliable data protection for Microsoft Small Business Servers. This robust suite features backup, restore, disaster recovery, single drive library support, Exchange Server, SQL Server, and SharePoint Services protection and recovery. A select family of powerful agents and options deliver robust storage management tools to meet diverse application needs for growing and upgrading storage

Both of these software have optional Extended 24/7 Support Warranties available for purchase. In addition you can purchase many software options including LEO (Library Expansion Option) and DLO (Desktop and Laptop Option).

LEO scales the media storage system by leveraging additional drives within multi-drive tape or optical autoloader/library storage systems. This option’s Advanced Device and Media Management (ADAMM) technology provides extensive configuration and management capabilities to include “lights-out” backup and restore operations, bar-code reader and portal support for both SCSI and Fibre-attached devices. Users can partition slots within a library to target backup jobs to a specific slot.

DLO is an optional agent that helps in backing up data even when spread across multiple user workstations. Most businesses rely on users to manually copy business critical data to a server. When users do not comply, the majority of business-critical information residing on employee workstations, desktop and laptop does not get protected. The Desktop and Laptop Option delivers continuous data protection to desktops and laptops whether in the office or on the road. Not only improving data protection and efficiency, this option enables users to restore their own files, and maintains synchronization between multiple desktops and laptops so the most up-to-date file versions are available on all of a user’s computers.
