Im Gegensatz zu z.B. Linux muß man nicht auf Treiberunterstützung warten. Windows ist im Gegensatz zu Linux (Linux arbeitet mit einem Zeitscheiben Modell) ein Real-Time System und daher prädestiniert für IO- Betrieb. Ein DataCore System erreicht bereits auf einem Knoten eine IO Leistung von bis zu 14.000.000 IO/s pro CPU Core. Sollte das einmal nicht ausreichen läßt sich die DataCore Umgebung als Grid auf bis zu 1.204 Nodes ausdehnen. Jeder DataCore Knoten kann bis zu 20GB Cache addressieren.

SANsymphony Product Introduction Thin Provisioning 12TB allocati No Agents on Hosts Volume Virtuale da 2TB (NVM) assegnato a ogni server Solo una piccola frazione del reale spazio fisico viene allocata ad ogni disco virtuale SANmelody alloca automaticamente lo spazio quando necessario SANmelody Category D adds even more capacity, performance capabilities, high availability and data protection features. The ability to automatically provision storage capacity is a unique feature of SANmelody that will save time, simplify administration and reduce wasted capacity. Finally, we get rid of the guessing. Instead, SANmelody elegantly auto-provisions just enough space, just-in-time to needy servers. It does so in real time by assigning very large “virtual disk images” to each server. By large, we mean the largest addressable disk an operating system can handle (often 2 terabytes). In much the same way that virtual memory operates, all of the servers think they have plenty of room. Physically, however, only a fraction of real space is assigned to the pool. The amount on day one is dictated by current actual requirements plus a reserve for near term growth. Those applications that consume additional capacity as time goes on, deplete the free space, many never reaching anywhere close to their 2 terabyte virtual allotment. SANmelody doles out additional real space in granular increments, say 128 MB and monitors for use before granting more. Over time, as the free space for the entire pool is chewed up, the low reserve mark is reached, triggering a notification. 20% reserve is common. Upon this alert, additional disks are acquired and added non-intrusive to the pool, upping the free space to a comfortable level once again. The servers, and more importantly their users and applications are never interrupted. 1TB Pool Lo spazio non allocato è disponibile per l’utilizzo da parte di ogni server Copyright 2000 DataCore Software Corporation

SANsymphony Product Introduction Snap Shot Snap shots Snap shots Point-in-time istantanei Immagini complete Snap shots da dischi FC a dischi SATA Produzione Copia Snapshot Disk Snapshots Take Place of Daily Backups Disk Servers can be configured to periodically generate daily 'snapshots,' or point-in- time copies, of critical volumes on separate disks -- eliminating the need for daily tape backups. The snapshots may be mounted just like a removable drive to rapidly restore an application to a known good image from the previous day. Where conventional tape backups can disrupt application processing for several hours, an online snapshot only requires a brief application pause to record the current state of the data. Immediately after a snapshot is taken, the 'live' source volume is released and applications may resume updates. SANmelody then captures subsequent changes to the data in real-time on a separate volume. This process dramatically reduces the time to create a "backup copy."

SANsymphony Product Introduction DataCore Software Fiber Channel connected Applications Server IP Clients Connected via iSCSI or AIM Client Backup Server Administrations Console The SANmelody disk server approach buys you several unique benefits: When the next machine runs out of capacity, you don’t need to buy yet another application-specific server. There’s no need to license and deploy another instance of the application just to address a capacity issue. In short, surplus capacity in one disk server is available to any other application that needs it. Disks are no longer dedicated to a single application.
