• 現有的虛擬化建議架構都是為了 Server Virtualization 設計的

• 小小的更動，大大的影響• IOPS per desktop multiplies• RAM kills –每 1 GB RAM 需要 2GB的儲存空間

• 對於穩定性的要求和Server 虛擬化一樣• 效能要求比Server 虛擬化更高!• 常見的規劃迷失

• 過度低估儲存的需求 – IOPS not Capacity• When is this exposed?

• 開機風暴 (Boot Storm)• Antivirus• Application Patching

The FAST Suite

• FAST Cache continuously ensures that the hottest data is served from high performance FLASH SSDs

• FAST VP (Virtual Pools)* optimizes storage pools automatically, ensuring that active data is being served from SSDs, while cold data is moved to lower cost disk tiers

• Together they deliver a fully automated FLASH 1st storage strategy for optimal performance at the lowest cost attainable

• Monitor and Tune the whole system with the complementary Unisphere QoS Manager and Unisphere Analyzer

自動化最高使用效能及容量管理

Virtual Blended Storage Pool

• Block services provided by VNX storage processor

• Tiered storage– Choose storage tiers

• Extreme Performance(Flash), Performance (SAS), Capacity (NL-SAS)

– Choose protection type (RAID 1, 5, 6)

• Pool has to have a single RAID type

– System builds RAID groups

• Tiers are aggregated into virtual blended storage pool
