Bare metal cloud FASS high performance elastic block storage solution

Distributed storage | Beijing Avenue yunhang Technology Co., Ltd

01 Background Overview

Compared with the public cloud model , Bare metal servers provide users with physical server rental services , It continues the unique advantage of non-destructive performance of physical machine , It can meet the strict requirements of core application scenarios for high performance and stability at the same time . Use bare metal server to monopolize client resources , Don't share with other customers CPU、 Memory, etc. , Performance can be fully exploited . Because of the complete isolation at the physical machine level , Can provide more security 、 Reliable computing resources . Bare metal servers can achieve performance that is no worse than physical servers , At the same time, it can realize the elastic expansion and use of resources , Fully automated operation and maintenance management , More and more attention is paid to financial securities 、HPC And so on 、 High data security requirements are welcomed by users .

02 Demand pain point

Bare metal cloud can realize elastic and automatic computing resource management , However, there is no powerful data storage matching scheme ：

1、 Not flexible enough 、 Complex operation and maintenance ： It is inconvenient to expand the capacity of bare metal server with local hard disk , Lack of unified management , Unable to allocate resources dynamically and reasonably , Capacity expansion requires a lot of manual intervention , Bring great cost growth .

2、 Resource solidification 、 The high cost of ： The business application of bare metal cloud requires high storage performance , Each host will be configured independently NVME disc , But each host SSD Resources cannot be pooled and dynamically allocated , Low resource utilization , The high cost of .

3、 A single point of failure 、 Low security ： The local hard disk mode lacks unified management and data protection , Become an obvious single point of failure of the system , Once the server or hard disk is damaged , It will cause serious consequences such as data loss and business interruption .

03 FASS High performance elastic block storage solution

△ Scheme topology

Storage pool mainly adopts Fully equipped NVMe Discoid FASS Construction of distributed full flash storage system ,FASS Use cross node SSD Resource to create a storage pool , And divide into multiple LUN volume , be based on 100Gb Ethernet or Infiniband The Internet , With iSCSI/iSER/NVMeoF The protocol maps to each bare metal host that needs to be stored .

FASS Every LUN Thin provisioned volumes , Space that can be allocated far more than actual physical resources , Meet the changing business needs of each host . The background can be used according to the essence of each host , Dynamically allocate physical resources .

As a standard distributed storage system ,FASS Support 512 Node Scale-out Expand , It can change with business needs , Easily increase capacity and performance by scaling horizontally , Meet the huge needs of cloud business .

04 Program advantages

Standard agreement 、 Excellent performance ——FASS The distributed full flash block storage solution adopts NVMe medium , Based on standards iSCSI、iSER、NVMeoF Can provide the ultimate I/O performance , Combined with the software layer XPE Engine design 、 Microcontroller technology 、 Lightweight metadata indexing and other mechanisms , The block storage end can reach 30 million nodes IOPS、 Microsecond delay , It can easily meet the stringent performance requirements of bare metal virtual machines .

High availability 、 Elastic expansion ——FASS The distributed full flash storage system adopts full live high availability architecture , Any node can be allowed to fail without interrupting the block storage service , High business availability .FASS Single node can achieve 100 All level IOPS, With the growth of cluster size, the linear growth of capacity and performance can be realized at the same time , Up to tens of millions of IOPS performance .

According to the need to use 、 Planning minimalism ——FASS Thin provisioned volumes are provided by default , You can ignore the actual physical space , Create a large capacity logical volume . Without any human intervention , It can meet the different and dynamic capacity requirements of different virtual machines , Dramatically simplify capacity management .

05 Business scenario

In new information technology 、 In the context of mobile Internet , The bare metal server based on distributed full flash block storage can meet the needs of Internet 、 Artificial intelligence 、 big data 、 Genetic engineering and other technology companies , With its ultra-high cost performance 、 High performance 、 Customizable 、 Send property rights and other advantages , Solve the problem of resource shortage of customers in the expansion period .
1、 Finance 、 Securities industry scene with high requirements for safety and supervision , Enterprises that have strict requirements for data security .
2、 High performance computing scenarios ： Supercomputing Center 、 High performance computing scenarios such as gene sequencing have a large amount of data processing , The computing performance of the server 、 stability 、 High real-time requirements .
3、 Core database scenario ： Some key database services cannot be deployed on virtual machines , It has to be exclusive through resources 、 Network isolation 、 Physical servers with guaranteed performance .

4、 Mobile application scenarios ： Around mobile apps , Especially the development of mobile games 、 test 、 go online 、 operating .
