Break Through Performance Bottlenecks
VirtualStor™ Extreme features a high-performance storage engine that significantly increases the I/O performance of a distributed storage system, by using Storage Class Memory (SCM) devices (NVDIMM) and NVMe/SSD as data caching and merging small I/Os into sequential I/Os to further improve IOPS. Data written in NVMe/SSD cache is protected by duplication, preventing data inconsistency from a single NVMe/SSD failure. SSD acceleration technology stores frequently accessed data in the SCM device and NVMe/SSD cache, breaking the bottleneck of scale-out storage systems that are traditionally not good at handling random reads.

With this technology, VirtualStor™ Extreme performs with stable low random read latency - as low as 1 ms on average, preventing unpredictable latency from impacting business critical applications demanding low and predictable response times. With up to 800,000 IOPS and 10GB/s throughput per chassis, VirtualStor™ Extreme brings blazing fast scale-out storage to fit scenarios like data analytics, high performance computing (HPC) and media broadcasting 4K streaming application workloads.

Unify Your Storage Islands
Over time data centers become a mix and match of many different types of storage (SAN, NAS, DAS etc.). This is due to budgets, availability of storage devices, immediate resource needs, and storage requirement needs. Mixing and matching storage types makes management far more complex as more and more storage devices become part of the data center. VirtualStor™ Extreme provides a unified storage platform, consolidating any type of traditional storage (SAN, NAS, and DAS) into a single massive storage entity, with Bigtera's unique storage virtualization technology. As more appliances are added, the appliances seamlessly become part of a single massive decentralized storage entity.

VirtualStor™ Extreme can be partitioned into storage of any type by abstracting the storage hardware from the control layer and supports creating network attached storage (NAS) and storage area networks (SAN) that can run simultaneously. These storage types are supported by several storage protocols: iSCSI / FC (SAN), CIFS / NFS (NAS), OpenStack Cinder RBD and Amazon S3 / Open-Stack Swift (Object Storage).

Legacy Storage Consolidation and Migration
During the storage purchase and upgrade process, IT management teams are often concerned about data silos caused by data spread across different storage systems from various vendors/technologies. However, it's also hard to justify the cost of replacing legacy storage systems which have run out of space when those systems are still good to work.

VirtualStor™ Extreme seamlessly migrates data to the new storage system without service down time. The application data is available even during the migration process. VirtualStor™ Extreme also features data consolidation to consolidate existing legacy storages (SAN, NAS, DAS) from any vendors into a single, massive, logical storage infrastructure so that money spent on legacy storage systems won't be wasted.
Squeeze Out Maximum Capacity
VirtualStor™ Extreme can use two replica copies or N+M Erasure Coding, to provide more efficient space utilization than other software defined storage with 3 replica copies. Administrators can also assign various services on Bigtera's unique multi-tenant storage technology "Virtual Storage" to virtually extend the available space and enable compression for backup or archiving. VirtualStor™ Extreme also automates efficient optimization of storage resources: Thin Provisioning functionality provides resources just as they are needed, and storage resources are balanced across storage nodes, so no single node carries more than their fair share of the load.

VirtualStor™ Extreme also optimizes SSD usage, using Storage-Class Memory and a new generation of caching algorithm optimization techniques to minimize SSD write amplification, reducing write wear and extending SSD service lifetime. VirtualStor™ Extreme can also notify the administrator when SSD life is running out and predict storage capacity and performance. These features help an administrator to plan ahead and decrease management headaches.

Easy & Powerful Management
VirtualStor™ Extreme features flexible and easy management of storage pools. With customizable size and number of pools and quota management, VirtualStor™ Extreme fits all kind of scenarios fulfilling the various business demands of enterprises. Service downtime caused by data migration due to storage replacement is a major headache to IT administrators. VirtualStor™ Extreme seamlessly migrates data from legacy storage (NAS, iSCSI or FC) in the background with no downtime. All data is available any time during migration even if it has not yet been migrated to VirtualStor™ Extreme.
100% Protection & Availability
VirtualStor™ Extreme data availability functions include data replication, erasure coding and self-repairing features. Erasure coding offers administrators an alternative to data replication, to ensure that there is no single point of failure for any of the data blocks. VirtualStor™ Extreme uses round-robin DNS and IP takeover services. Round-robin DNS uses a list of IP addresses for workload balancing - if any of the appliances encounter issues, the remaining appliances seamlessly take over application and workload services by taking over the IP of the appliance that encounters issues. VirtualStor™ Extreme object storage can support Server-Side Encryption (SSE) to protect the object data stored with S3 API and uses Intel® AES-NI encryption technology to accelerate Server-Side Encryption (SSE). Encryption can be enabled for critical data or applications, while data that has a lower level of confidentiality can be left unencrypted.
VirtualStor Extreme Architectural Overview
Total Flexibility
Users can utilize VirtualStor™ Extreme to unify and extend the capacity of their existing storage systems or can seamlessly migrate data from their legacy storage devices to build a new storage system almost without any service downtime. Users can set up a new VirtualStor™ Extreme storage system with as little as 2U of rack space and 23TB of storage capacity or can scale out to achieve multi-petabyte storage capacity.

全快閃記憶體
全快閃記憶體是什麼? 全快閃記憶體(All Flash)儲存系統(也稱為全快閃記憶體陣列 (AFA) 或固態儲存硬碟 (SSD) 系統),是一個僅使用快閃記憶體媒介裝置(如:非揮發性記憶體或SATA SSD)進行的外部儲存陣列。 快閃記憶體儲存代替長期以來網路儲存系統使用的硬碟 (HDD)。與硬碟相比,使用快閃記憶體儲存系統的好處包括更低的延遲、 更高的 IOPS、更高的儲存密度和更低的功耗。
軟體定義儲存
軟體定義儲存是甚麼? 軟體定義儲存(SDS)就是所謂的虛擬化儲存系統,是電腦資料儲存的一個進階概念,它以「軟體」控制的方法來決定資料儲存的方針及管理方式,而與儲存的「硬體」本身無關聯。SDS可以在軟體定義資料中心運作,也可作為獨立技術運行。提供重複資料刪除、複製、精簡資源調配和備份等管理策略。
水平擴充
水平擴充是什麼? 水平式擴充(Scale Out)是在伺服器內增加更多的虛擬化節點或是將節點移至另一台伺服器。就如同在分散式軟體應用程式架構中增加一台新的電腦。
