Top Five Reasons to Go for small and medium enterprises NAS

Posted on March 18th, 2010

What is the best storage solution for small and medium enterprises from unforeseen data growth both privacy and now access to critical files for the users? Of the three most common storage architectures, direct-attached storage (DAS), Network Attached Storage (NAS) and Storage Area Networks (SAN), NAS has been the first choice for most SMEs.

Accessible and easy

NAS provides the accessibility of 10Gb Ethernet with developments, such as SCSI over IP(ISCSI). In addition, communicate, NAS devices on an NFS and CIFS Fiber Channel SAN devices, while the block-level data transmitted over FCP (Fiber Channel Protocol). Almost every IT administration can connect over a LAN or WAN to the data files NAS. With SANs, users will be limited to servers with SCSI connectivity in fiber, while the NAS configurations provide additional information to share files on Windows and Unix.

NAS must be connected to the network if sufficient bandwidthsupport the traffic generated by a high volume of data. NAS is the ideal solution for file-centralization of enterprise users, but for most medium-sized businesses to run disk-intensive applications and enterprise-level centralized storage environment for their campus wants is a SAN solution.

Here are my top 5 reasons for NAS is the right choice for small and medium

1. Solution cost

Leverage existing investments in Ethernet. 10Gb Ethernet is rapidlysufficient for most applications, SMB and iSCSI support.
Sufficient in-house IT generalists, probably for the management / administration NAS.

2 iSCSI NAS devices can simulate certain SAN-like capabilities

iSCSI is an infrastructure or very low hardware requirements. Normally, an industry standard gigabit network adapter or work 10Gb and turn. These are many NAS devices the ability to act as an iSCSI SAN.
3. Perform advanced tasks

ANAS device to operate at the file level, during the execution of a block-level SAN. For users who have access to files, NAS makes sense. Database and application servers require block-level data can be supported with iSCSI SAN solutions, as mentioned above.
It is used depending on the file system, users can perform advanced NAS such as the use of specific tariffs, enforcement of security restrictions, file indexing and other tasks. Your operating system or your NAS appliance The operating system therefore allows files to the network will be issued.

4. Especially for small and medium enterprises with value-added features built-in.

NAS is designed for the exchange of files to network clients. But most also offer other features such as multi-protocol file sharing, some kind of backup media and tools for the mismanagement of files such as quota and the user community. For most small and medium businesses, is a NAS solution makes perfect sense.

5. Calendar for significant growth> Storage

Virtualization: Because NAS devices, which serve as a network drive, the popularity of virtualization bring their skills to the fore once again. This is because, its much more efficient to use a network drive to store files that the user is in a virtual server. Plus, frequently changing user files tend to degrade performance and complicate the backup to a virtual server. However, obtaining a virtual server to take care of partitions of the users or folders on a map NASsituation.
NAS Gateway: Users can no longer do so with an either-or situation, rather than deciding to choose the storage technology. NAS gateways are a relatively new type of device, which behave similarly to SAN-attached file server, but with better performance and user management major. Usually a NAS gateway is not in stock, and instead will use your SAN to provide the space intelligently and simultaneously serve the first file on the network. So ifDoes your organization distribute very demanding server applications, such as large databases, mail servers and virtualization, can accommodate up to a SAN-NAS-devices to use, and more.

For most SMB needs, I recommend the following NAS systems from HP (NYSE: HPQ). Visit www.shopricom.com/AP803A learn more about these products.

iSCSI vs. FC for Meeting Mission Critical Requirements

Posted on March 11th, 2010

Introduction

Mission Critical Data is just what its name says: critical to the core functioning of an enterprise. Mission critical data must be available 24×7 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

Mission Critical Requirements and SANRAD’s Solutions

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:

o High Availability: Storage systems and their mission critical data must be available 24×7.

There is no leeway for downtime. Every minute of downtime equals a loss of revenues and credibility for an enterprise.

o 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.

o 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.

o 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.

SANRAD has taken these requirements and provided comprehensive solutions in a single centrally

managed platform using iSCSI technology.

o 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.

o 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.

o 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.

o 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.

Benefits of iSCSI SAN over FC SAN

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.

The FC investment comes from four fronts:

o Infrastructure: An FC network demands FC switches, hubs and bridges along with specific

GBICs and cabling. In addition, each host requires dedicated FC HBAs.

o 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.

o Software: A variety of software tools is needed to manage all of this new equipment as well as

the dedicated FC HBAs.

o Human Resources: dedicated group of FC storage and networking IT administrators is

needed to manage all of this.

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.

SANRAD’s V-Switch 3000 provides a single integrated hardware/software solution to SAN management:

o 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.

o 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.

o 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.

o 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

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.

o Small: 8 servers accessing a net capacity of 500GB.

o Small – Medium: 12 servers accessing a net capacity of 1TB.

o Medium: 16 servers accessing a net capacity of 1.5TB.

o Medium – High: 24 servers accessing a net capacity of 2TB.

o High: 32 servers accessing a net capacity of 3TB.

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.

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.

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.

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

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.

Top Five Reasons For SMBs to Choose NAS

Posted on March 10th, 2010

What is the best storage solution for SMBs facing unpredictable data growth-both data protection and right-now access to critical files for users? Of the three most common storage architectures, direct attached storage (DAS), network attached storage (NAS) and storage area networks (SAN), NAS should be the first choice for most SMBs.

Affordable, Simple

NAS offers affordability of 10GB Ethernet with developments like SCSI over IP (iSCSI). Furthermore, NAS devices communicate over a NFS and CIFS Fibre Channel while SAN devices transmit block-level data over FCP (Fibre Channel Protocol). Nearly any IT administer can make connects over a LAN or WAN to the NAS data files. With SANs, users are limited to servers using SCSI Fibre connectivity, while NAS configurations offer wider data file sharing over both Windows and Unix operating systems.

NAS should be connected in the network where sufficient bandwidth supports the traffic generated by high data volume. NAS is an ideal solution for file centralization amongst corporate users, but for most midsize to enterprise companies running disk-intensive applications and that want enterprise-wide storage centralization for their campus environment, a SAN is the solution.

Here are my Top 5 reasons NAS is the right choice for SMBs

1. Lower-cost solution

Leverage existing investment in Ethernet. 10Gb Ethernet is fast enough for most SMB applications and supports iSCSI.
In-house IT generalists probably sufficient to administer/manage NAS.

2. iSCSI allows NAS appliances to mimic some SAN-like functionality

iSCSI has very low infrastructure or hardware requirements. Usually a industry-standard gigabit or 10Gb network card and switch will work. This gives many NAS devices the ability to act as an iSCSI SAN.

3. Perform more advanced tasks

A NAS device works at the file level, while a SAN operates at the block level. For users needing access to files, NAS makes sense. Database and application servers requiring block-level data can be supported with iSCSI SAN solution, as mentioned above.
Depending upon the file system in use, NAS lets users perform more advanced tasks, such as specify usage quotas, enforce security constraints, perform file indexing, and the other tasks. Your operating system or your NAS appliance’s operating system then allows those files to be shared on the network.

4. Purpose-built for SMBs with value-added features.

NAS appliances are designed for sharing files to networked clients. But most also offer other features, such as multi-protocol file sharing, some kind of backup support, and rich file management tools like advanced quotas and utilization reporting. For most SMBs, a NAS solution makes perfect sense.

5. Clear growth roadmap for storage

Virtualization: Since NAS appliances are designed to serve as a network drive, the popularity of virtualization is bringing its capabilities to the fore once again. That’s because is far more efficient to use a networked drive to store user files within a virtual server. Plus, frequently changing user files will tend to degrade performance and complicate backup on a virtual server. However, getting a virtual server to map user partitions or folders to a NAS take care of this situation.
NAS gateways: Users are no longer faced with an either/or situation when deciding what storage technology to choose. NAS gateways are a fairly new breed of device that behave much like SAN-attached file server, but with improved performance and more advanced user management. Usually a NAS gateway will not have any storage, and instead will use your SAN to provide the raw storage space and while intelligently serving files across your network. So when your organization does deploy truly demanding server applications such as large databases, mail servers, and virtualization hosts-you can scale up to a SAN while still utilizing NAS devices.

For most SMB needs, I recommend the following NAS systems by HP (NYSE:HPQ). You can visit www.shopricom.com/AP803A to learn more about these products.
