Introduction
Business critical data is just what its name says: critical to the core functioning of an enterprise. Mission-critical data must be available 24x7 and fully backed up for immediate recovery in case of disaster. Companies are constantly in search of reliable, efficient, convenient and cost-effective ways of meeting those needs. SANRAD V-Switch 3000 uses iSCSI technology to centrally consolidate, manage, and restore business-critical dataat a fraction of the cost of capital and human resources, the existing FC SAN technologies
Mission Critical Requirements and SANRAD's Solutions
Storage Area Networks (SANs) are used to manage business-critical data and how they have developed, storage and network administrators to manage SAN identified three key requirements of a to this critical data:
o High Availability: Storage systems and their mission-critical data mustAvailable 24x7.
There is no room for downtime. Every minute that corresponds to a loss of revenue and credibility of a company.
o Remote Backup and Recovery: Data must be off site before secured to allow for remote disaster recovery in case of. Experts estimate that 30% of the companies could not be a recovery
catastrophic loss of data and backups on the site is useless if the premises are destroyed.
o Manageability: A SAN-management system mustcan be centrally managed and provide a consolidated storage solution accommodating different storage subsystems and infrastructures. SAN management must not exercise In addition, the load on the network and storage administration staff.
o Dynamic extensibility: Storage networks must be able to grow with the company. The systems can not be taken offline in order to meet this growth, and no one wants to search for new storageManagement solutions every time there is a growth spurt.
SANRAD has to take into account these requirements and provided comprehensive solutions in a single central
managed platform using iSCSI technology.
o SANRAD's High Availability: The V-Switch 3000 is fully redundant hardware failures to weather power, processor and fan. The V-Switch 3000 configuration database to Flash and Compact Flash memory written. The software based IP-SAN configuration provides automatic V-Switch3000 failover and failback, and data mirroring. No single point of failure ensures high availability.
o SANRAD's Remote Backup and Recovery: The V-Switch 3000 to provide global IP-based storage networks so that critical data SAN transfer to remote locations within the IP.
o SANRAD's Manageability: The V-Switch 3000 enables storage pooling across multiple platforms and infrastructure, eliminating the need for host agents. The V-Switch3000
Functions at the network level and is thus independent of the host operating system and storage vendors. The V-Switch 3000 provides storage virtualization and precise LUN carving of the pooled storage,
Supporting volume concatenation, mirroring and striping. Accessed the GUI-based storage management server Pro is used locally, centrally configure volumes, monitor the status and
Management of the storage pool.
o SANRAD's DynamicExtensibility: The V-Switch 3000 uses existing adapters, network and disk subsystems to form a sophisticated SAN solution TB-72 GB to 16 years. New
Storage devices can be added dynamically and their volumes virtualized performance in real time without the system offline or affecting function volume. Two V-Switch 3000's
can be connected in a SAN to provide a cluster of inter-V-Switch 3000 Load Balancing and Failover form.
Benefits of iSCSISAN via FC SAN
When you create a SAN, where companies, the traditional answer is FC-SAN. However, the investment required to implement an FC SAN is often beyond the capabilities of a young company. As a result, companies are slow in their growth phase, the inevitable upgrade to a SAN and therefore gambling
to store their business critical data.
The FC investment comes from four areas:
o Infrastructure: An FC network demands FC switches, hubsand bridges as well as specific
GBICs and cabling. In addition, each host requires dedicated FC HBAs.
o Storage: The storage devices have to be expensive FC RAID arrays. If a company wants to
to maintain his JBOD stores, it has to buy virtualization devices to convert JBODs
Use in an FC SAN.
o Software: A variety of software tools needed to manage all these new devices as well as
the dedicated FC HBAs.
oHuman Resources: dedicated group of FC storage networking and IT Administrators
are needed to manage all this.
For a growing company, this represents a significant investment in capital and human resources to acquire
Implement and manage only one aspect of the company's data flow.
SANRAD V-Switch 3000 provides an integrated hardware / software solution for SAN management:
o Infrastructure: The V-Switch 3000 uses a company of existingIP infrastructure, including
existing Ethernet switches, cables, GBICs and SFPs. Many of the existing NIC is all that is necessary
to connect to the SAN connection.
o Storage: The V-Switch 3000 supports existing legacy storage devices, both FC &
SCSI, RAID and JBOD, it is not necessary to purchase new equipment storage. Because of the V-Switch
3000 storage pooling capabilities, companies can have an increase in usable spaceSpace.
o Software: The V-Switch 3000 includes both hardware and a software component. There is no need
additional software on the included storage per storage management tool.
o Human Resources: As the V-Switch 3000, the company works through the existing
Internet network, minimal additional knowledge or training is necessary to implement or manage
SAN. The existing network or storage administrator is readilyqualified to manage SANRAD's iSCSI SAN.
Business case: V-Switch 3000 compared FC
Typical SAN topographies SAN can be divided in 5 groups according to the number of servers accessing the SAN and the net storage capacity.
o Small: 8 servers accessing a net capacity of 500 GB.
o Small - Medium: 12 servers accessing a net capacity of 1 TB.
o Medium: 16 servers accessing a net capacity of 1.5 TB.
o Medium - High: 24 servers accessing a net capacity2 TB.
o High: 32 servers accessing a net capacity of 3 TB.
To best understand the, the budgetary impact of the introduction of an FC SAN compared to an iSCSI SAN SANRAD consider the costs of each company for an average of sixteen hosts accessing a storage pool of 1.5TB.
In an FC SAN, this would require two FC switches. Prior to the FC switches there are five servers
Clusters, such as Exchange, SQL and file servers, plus six individual servers. Each server needsFC
Software and each server has two HBAs, each on a different switch for a total of thirty-two HBAs.
Downstream of the FC switches is a RAID system with RAID 5 and hot spare functions and has a capacity
of 1.5 TB.
In a SANRAD V-Switch 3000 SAN, this would also require two V-Switch 3000's. Prior to the V-Switch
3000s, there are two multi-Gbit switches but no special host software or HBAs are required. Downstream
the V-Switch 3000s are the legacy SCSI orFC JBODs with a net capacity of 1.5 TB mirrored.
For a medium-sized enterprises, implementation of a FC SAN for mission-critical data is more than twice as expensive as a SANRAD iSCSI SAN. This effort does not take into account the Total Cost of Ownership (TCO), such as FC cabling installation costs, improve cost of human resources regularly FC
Software and maintain two separate networks, or the cost of replacing an FC RAID device compared to a JBOD
Hard drive. Since the size of a companygrows, the costs Par between FC and iSCSI SAN.
Conclusion
SANRAD iSCSI SAN offers all the key requirements needed for the management of the SAN, backup and recovery
mission-critical data with added benefits over FC SAN. SANRAD V-Switch 3000 provides a single
integrated hardware / software solution for SAN management, including storage pooling virtualization,
Mirroring, striping, and remote backup. The IP-based iSCSI SAN allows remote memory accessand
provides greater flexibility in the location network and storage components within a company and
does so at a fraction of the cost of an FC SAN.
