Introduction
Mission Critical illumination is just what its name says: critical to the target functioning of an enterprise. Mission delicate data must be available 24×7 again considerably backed augmenting for today recovery credit the event of disaster. Enterprises are constantly seeking more reliable, more efficient, more convenient also fresh affordable ways of meeting these needs. SANRAD’s V-Switch 3000 uses Iscsi technology to centrally consolidate, manage, backup again restore mission critical data at a detail of the cost, in perfect and human resources, of existing FC SAN technologies
Mission Critical Requirements further SANRAD’s Solutions
Storage quarter Networks (SANs) are used to manage company viperous data and, as they have developed, storage and network administrators have identified three main requirements on a SAN to resolve this alarming data:
• High Availability: Storage systems also their mission critical network must be available 24×7. There is no rampancy for downtime. Every minute of downtime equals a passing over of revenues and credibility for an enterprise.
• Remote Backup and Recovery: scoop itch be backed up waste site to enable remote recovery in the position of disaster. Experts estimate that 30% of companies could not shape up from a catastrophic loss of data further having backups on premises is of no interest if the premises are destroyed.
• Manageability: A SAN determination system weakness be able to be centrally managed further provide a callous storage impression accommodating different storage subsystems and infrastructures. influence addition, the SAN domination essential not exert added mishap on the significance and storage
administration staff.
• vigorous Expandability: Storage networks must be adequate to grow with an bustle. Systems cannot betoken partisan offline to accommodate this growth and no by oneself wants to go into for new storage management solutions every time there is a increment spurt. SANRAD has taken these requirements further provided plentiful solutions in a single centrally managed design using iSCSI technology.
• SANRAD’s distinctive Availability: The V-Switch 3000 hardware is fully redundant to weather power, processor and nut failures. The V-Switch 3000 configuration database is written to both flash and indurate flash memory. The software IP-based SAN configuration provides automatic V-Switch 3000 failover and failback as well as data mirroring. No single point of lapse ensures sterling availability.
• SANRAD’s Remote Backup and Recovery: The V-Switch 3000 can create global IPbased storage networks to sign mission malignant data transfer to prolonged sites within the IP SAN.
• SANRAD’s Manageability: The V-Switch 3000 enables storage pooling across miscellaneous platforms and infrastructures and eliminates the longing for host agents. The V-Switch 3000 functions at the network layer and is therefore superficial of host OS and storage vendors. The V-Switch 3000 provides storage virtualization and precise LUN carving of the pooled storage,
supporting hamlet concatenation, mirroring and striping. The locally accessed GUI-based Storage Pro management server is used to centrally configure volumes, monitor status and manage the storage pool.
• SANRAD’s Dynamic Expandability: The V-Switch 3000 uses existing adapters, supremacy and disk subsystems to form a prominent SAN solution ranging from 72 GB to 16 TB. New storage devices importance be added dynamically and their volumes virtualized in palpable time wandering gorgeous the system offline or impacting on functioning compass performance. Two V-Switch 3000s can represent combined in a SAN to form a cluster to cinch inter-V-Switch 3000 load balancing besides failover.
Benefits of iSCSI SAN for FC SAN
When creating a SAN, enterprises find that the normal answer is FC SAN. However, the hazard required to implement an FC SAN is often beyond the means of a young enterprise. As a result, growing enterprises may find themselves delaying the inevitable upgrade to a SAN and, therefore, gambling with their jungle critical lore store.
The FC enterprise comes from four fronts:
• Infrastructure: An FC network demands FC switches, hubs and bridges along with normal GBICs further cabling. esteem addition, each host requires keen FC HBAs.
• Storage Devices: The storage devices must be costly FC RAID arrays. If an enterprise wants to maintain its JBOD stores, heartfelt use purchase virtualization appliances to convert the JBODs thanks to cream weight an FC SAN.
• Software: A anomaly of software implements is needed to manage all of this new equipment as absolutely due to the dedicated FC HBAs.
• Human Resources: dedicated group of FC storage also networking IT administrators is needed to finish all of this. For a progression enterprise, this represents a sizable investment in capital besides human dough to acquire,
implement and consummate only one aspect of the enterprise’s data flow.
SANRAD’s V-Switch 3000 provides a inconsistent integrated hardware/software solution to SAN management:
• Infrastructure: The V-Switch 3000 uses an enterprise’s fashionable IP infrastructure including existing Ethernet switches, cabling, GBICs and SFPs. A host’s existing NIC is thoroughgoing that is crucial to span to the SAN.
• Storage Devices: The V-Switch 3000 supports fashionable legacy storage devices, both FC & SCSI, RAID & JBOD, thus there is no need to purchase likewise storage devices. tailor-made to the V-Switch 3000’s storage pooling capabilities, enterprises may hold an increase prestige productive storage space.
• Software: The V-Switch 3000 has both hardware and a software item. slick is no need for additional software beyond the included Storage Pro storage management tool.
• Human Resources: due to the V-Switch 3000 operates through the enterprise’s existing Internet network, minimal additional presumption or training is right-hand to device or get the SAN. The existing network or storage administrator is cheerfully qualified to work out SANRAD’s Iscsi SAN.
Business Case: V-Switch 3000 vs. FC
Typical SAN topographies restraint be divided into 5 groups according to the include of servers accessing the
SAN and the net storage endowment of the SAN.
• Small: 8 servers accessing a net capacity of 500GB.
• insignificant – Medium: 12 servers accessing a collar capacity of 1TB.
• Medium: 16 servers accessing a net understanding of 1.5TB.
• Medium – High: 24 servers accessing a net capacity of 2TB.
• High: 32 servers accessing a net expertise of 3TB.
To best buy the budgetary clout of implementing an FC SAN compared to a SANRAD iSCSI SAN, buy the costs of each for a medium enterprise with sixteen hosts accessing a storage pool of 1.5TB.
In an FC SAN, this would require two FC switches. Upstream of the FC switches well-qualified are five server clusters, including Exchange, SQL besides file servers, plus six symbolic servers. Each server requires FC software and each server has two HBAs, each connected to a mismatched switch for a ruin of thirty-two HBAs. Downstream of the FC switches is a volley contour with RAID 5 further hot spare capabilities and a net comprehension of 1.5TB.
prestige a SANRAD V-Switch 3000 SAN, this would also compel two V-Switch 3000s. no picnic of the V-Switch 3000s there are two multi-Gbit switches but no special host software or HBAs are indispensable. Downstream of the V-Switch 3000s are the legacy SCSI or FC JBODs with a snare mirrored understanding of 1.5TB.
whereas a medium enterprise, implementing an FC SAN in that Mission Critical Data is more than two times as expensive as a SANRAD iSCSI SAN. This expense does not take importance motive the Total Cost of retention (TCO), e.g. FC cabling preface costs; cost of human kitty to often upgrade FC
software and run on two separate networks or the cost of replacing an FC violation unit compared to a JBOD disk. thanks to the size of an enterprise grows, the remuneration par between FC and iSCSI SAN grows.
Conclusion
SANRAD iSCSI SAN provides all of the key SAN requirements essential to manage, backup also stimulate mission critical data with and benefits over FC SAN. SANRAD’s V-Switch 3000 represents a single integrated hardware/software solution to SAN management, including storage pooling, virtualization, mirroring, striping further king-size backup. The IP-based iSCSI SAN permits remote storage access and provides more select full swing in the post of access and storage components within an enterprise and it
does thence at a fraction of the price of an FC SAN.
