Introduction
Laptop Battery Mission 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 the event of disaster.
Enterprises are constantly seeking more reliable, more efficient, more convenient and more affordable ways
of meeting these needs. SANRAD's V-Switch 3000 uses Iscsi technology to centrally consolidate,
manage, backup and restore mission critical data at a fraction of the cost, in capital and human resources,
of existing FC SAN technologies
"Now that we have Acronis True Image 7.0 installed, network managers are able to create identical disk images of the live servers and recover the system within several minutes. Should there be a computer disaster, consuming software reinstallations or configuring the systems to meet our requirements. We will be working exactly the way we were before the failure. effective server protection sending employees back to work quickly without waiting for network repairs, " Ulmer said.

Mission Critical Requirements and SANRAD's Solutions
Description Have a friend with a laptop Do they always complain about the heat Cool them down with HandStands' Cool Lift. Designed to help promote air flow and reduce heat, the Cool Lift is perfect for notebook computers with the latest hot processors from Intel, AMD, Motorola, or IBM. Proof Shields for Laptops help prevent scratches from normal laptop use. Proof Shield. It even completely disappears when applied!
Microsoft Storage Area Networks (SANs) are used to manage mission critical data and, as they have developed,
storage and network administrators have identified three main requirements on a SAN to manage this
critical data:
"Computer industry analysts estimate that some 60 percent of all corporate data exists only on desktop and laptop computers, " said Walter Scott, CEO of Acronis. "Incorporating Acronis True Image with New Mexico Software backup server is the ideal solution to capture that corporate data and ensure that it is not lost. While traditional server backups are effective for protecting server data, every company should have a combination of server and workstation backup plans."
Laptop Computers . High Availability: Storage systems and their mission critical data must be available 24x7.
There is no leeway for downtime. Every minute of downtime equals a loss of revenues and
credibility for an enterprise.
"Not only did Acronis meet this requirement, purpose hardware that otherwise would not be required", he added.
Laptop Computer . Remote Backup and Recovery: Data must be backed up off site to enable remote recovery
in the event of disaster. Experts estimate that 30% of companies could not recover from a
catastrophic loss of data and having backups on premises is of no use if the premises are
destroyed.
And then, of course, we have the Standalone Server product, which is called Acronis True Image Server for Windows or Linux and that will manage a single standalone server. What type of computers can we back up, because in a medium to a large sized, even some small sized businesses, who knows what kind of computers they have They may have laptops, they may have desktops, they may just have anything and everything
Desktop Computer . Manageability: A SAN management system must be able to be centrally managed and provide
a consolidated storage solution accommodating different storage subsystems and infrastructures.
In addition, the SAN management must not exert added strain on the network and storage
administration staff.
Notebooks . Dynamic Expandability: Storage networks must be able to grow with an enterprise. Systems
cannot be taken offline to accommodate this growth and no one wants to search for new storage
management solutions every time there is a growth spurt.
Lenovo
SANRAD has taken these requirements and provided comprehensive solutions in a single centrally
managed platform using iSCSI technology.
Hard Drive
. SANRAD's High Availability: The V-Switch 3000 hardware is fully redundant to weather
power, processor and fan failures. The V-Switch 3000 configuration database is written to both
flash and compact 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 failure ensures
high availability.
Travelstar . SANRAD's Remote Backup and Recovery: The V-Switch 3000 can create global IPbased
storage networks to allow mission critical data transfer to remote sites within the IP SAN.
For more information on Disaster Recovery applications, see SANRAD's White Paper:
Continuous Data Availability Solutions using SANRAD's iSCSI Virtualization Switch.
Gateway . SANRAD's Manageability: The V-Switch 3000 enables storage pooling across multiple
platforms and infrastructures and eliminates the need for host agents. The V-Switch 3000
functions at the network layer and is therefore independent of host OS and storage vendors. The
V-Switch 3000 provides storage virtualization and precise LUN carving of the pooled storage,
supporting volume 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.
Laptop Parts . SANRAD's Dynamic Expandability: The V-Switch 3000 uses existing adapters, network
and disk subsystems to form a sophisticated SAN solution ranging from 72 GB to 16 TB. New
storage devices can be added dynamically and their volumes virtualized in real time without
taking the system offline or impacting on functioning volume performance. Two V-Switch 3000s
can be combined in a SAN to form a cluster to provide inter-V-Switch 3000 load balancing and
failover.
Software Benefits of iSCSI SAN over FC SAN
Hard Drives When creating a SAN, enterprises find that the traditional answer is FC SAN. However, the investment
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 mission critical data store.
Electronics The FC investment comes from four fronts:
Canon . Infrastructure: An FC network demands FC switches, hubs and bridges along with specific
GBICs and cabling. In addition, each host requires dedicated FC HBAs.
Desktop Pc . Storage Devices: The storage devices must be costly FC RAID arrays. If an enterprise wants
to maintain its JBOD stores, it must purchase virtualization appliances to convert the JBODs for
use in an FC SAN.
Desktop Computers . Software: A variety of software tools is needed to manage all of this new equipment as well as
the dedicated FC HBAs.
Think Pad . Human Resources: dedicated group of FC storage and networking IT administrators is
needed to manage all of this.
Repair For a growing enterprise, this represents a sizable investment in capital and human resources to acquire,
implement and manage only one aspect of the enterprise's data flow.
Data Recovery SANRAD's V-Switch 3000 provides a single integrated hardware/software solution to SAN management:
Cisco . Infrastructure: The V-Switch 3000 uses an enterprise's existing IP infrastructure including
existing Ethernet switches, cabling, GBICs and SFPs. A host's existing NIC is all that is needed
to connect to the SAN.
Keyboard . Storage Devices: The V-Switch 3000 supports existing legacy storage devices, both FC &
SCSI, RAID & JBOD, so there is no need to purchase new storage devices. Due to the V-Switch
3000's storage pooling capabilities, enterprises may have an increase in usable storage space.
Monitor . Software: The V-Switch 3000 has both hardware and a software component. There is no need
for additional software beyond the included Storage Pro storage management tool.
Desktop . Human Resources: Because the V-Switch 3000 operates over the enterprise's existing
Internet network, minimal additional knowledge or training is needed to implement or manage the
SAN. The existing network or storage administrator is readily qualified to manage SANRAD's
Iscsi SAN.

Business Case: V-Switch 3000 vs. FC
Refurbished Laptops Typical SAN topographies can be divided into 5 groups according to the number of servers accessing the
SAN and the net storage capacity of the SAN.
Wipro . Small: 8 servers accessing a net capacity of 500GB.
Lap Top . Small - Medium: 12 servers accessing a net capacity of 1TB.
Refurbished . Medium: 16 servers accessing a net capacity of 1.5TB.
Memory . Medium - High: 24 servers accessing a net capacity of 2TB.
Intel . High: 32 servers accessing a net capacity of 3TB.
As400 To best understand the budgetary impact of implementing an FC SAN compared to a SANRAD iSCSI SAN,
consider the costs of each for a medium enterprise with sixteen hosts accessing a storage pool of 1.5TB.
Averatec In an FC SAN, this would require two FC switches. Upstream of the FC switches there are five server
clusters, including Exchange, SQL and file servers, plus six individual servers. Each server requires FC
software and each server has two HBAs, each connected to 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 capabilities and a net capacity
of 1.5TB.
Hardware
In a SANRAD V-Switch 3000 SAN, this would also require two V-Switch 3000s. Upstream of the V-Switch
3000s there are two multi-Gbit switches but no special host software or HBAs are required. Downstream of
the V-Switch 3000s are the legacy SCSI or FC JBODs with a net mirrored capacity of 1.5TB. The cost of
Dual Xeon
For a medium enterprise, implementing an FC SAN for Mission Critical Data is more than two times as
expensive as a SANRAD iSCSI SAN. This expense does not take into consideration the Total Cost of
Ownership (TCO), e.g. FC cabling installation costs; cost of human resources to regularly upgrade FC
software and maintain two separate networks or the cost of replacing an FC RAID unit compared to a JBOD
disk. As the size of an enterprise grows, the cost par between FC and iSCSI SAN grows.

Conclusion
Seagate SANRAD iSCSI SAN provides all of the key SAN requirements needed to manage, backup and restore
mission critical data with added 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 and remote backup. The IP-based iSCSI SAN permits remote storage access and
provides greater flexibility in the location of network and storage components within an enterprise and it
does so at a fraction of the cost of an FC SAN.
