什是SAN ? ... 展開回答
.
What storage area networks are used forFibre Channel (FC) SANs have the reputation of being expensive, complex and difficult to manage. Ethernet-based iSCSI has reduced these challenges by encapsulating SCSI commands into IP packets that don't require an FC connection.
The emergence of iSCSI means that instead of learning, building and managing two networks -- an Ethernet local area network (LAN) for user communication and an FC SAN for storage -- an organization can use its existing knowledge and infrastructure for both LANs and SANs. This is an especially useful approach in small and midsize businesses that may not have the funds or expertise to support a Fibre Channel SAN.
Organizations use SANs for distributed applications that need fast local network performance. SANs improve the availability of applications through multiple data paths. They can also improve application performance because they enable IT administrators to offload storage functions and segregate networks.
Additionally, SANs help increase the effectiveness and use of storage because they enable administrators to consolidate resources and deliver tiered storage. SANs also improve data protection and security. Finally, SANs can span multiple sites, which helps companies with their business continuity strategies.
Availability:
SAN storage is in general more reliable than DAS attached disk. This can save your company money by avoiding application outages. The cost of an hour of application downtime varies from company to company but can exceed millions in some cases.
Disk utilization:
When buying server-attached storage most people buy more than they currently need so they can "grow into" the storage. The space that is unutilized is wasted until it is needed. In SANs, that space can be "assigned" to any server that needs more storage, thus deferring new storage purchases. Using DAS, I find that a 40% utilization rate is high whereas in a SAN, you can get to the ultimate 80/20 (used/unused) ratio without a problem.
Management:
Using DAS you need to manually install new disks to add storage. In a SAN you can remotely assign it to a server. No downtime and perhaps not even a reboot is required if the OS can handle it. You can manage ALL your storage GLOBALLY from a single console.
Backup:
Using snapshots and data replication can save your backside when disasters happen and using a SAN for centralizing data backup can improve recovery time dramatically while reducing overall costs by sharing tape resources and eliminating backup windows.
In David's white paper, he lists a 29 case scenario where SAN gives better TCO and ROI on a dollar per MB basis including:
Case 1-Increased disk utilization
Case 2-Deferring disk procurement
Case 3-Terabytes (TB)-per-administrator improvement
Case 4-Reduce data center rack/floor space
Case 5-Deferring tape library procurement
Case 6-New disaster recovery (DR) capabilities
Case 7-On-line recoverability options
Case 8-Improved data path availability
Case 9-Reduction of general-purpose UNIX and Microsoft Windows NT servers
Case 10-Improve LAN/WAN performance, avoid upgrades
Case 11-Reduce/eliminate backup servers
Case 12-Reduce/eliminate batch, backup windows
Case 13-Storage on demand

市面上的NAS隨處可見,SOL NAS 的價值是? ... 展開回答
A. 這便是家用級NAS和企業級商用型NAS的不同處,表現在多方面。
硬體方面 - 平台本身即是伺服器,此外還特別注重多顆硬碟資料的保護,最直接、最不出錯的方式,便是採用硬體式RAID。軟體式RAID在超過8顆硬碟之後的負擔,有時是導致災害的原因。尤其是為了節省成本,使用一般級的硬碟,以軟體式RAID製作大磁碟使用,更是需要外留心。
軟體方面 - 建立了共用磁碟之後,個別的存取權限控管,在深度和細緻程度上有一些差距。
