Get What You Need with XEBS

Traditional distributed storage solves the problem of capacity limits and scale-out capability of dedicated storage devices under large capacity and cold data scenarios. However, it cannot smoothly replace the traditional SAN storage in terms of the adaptability breadth to application scenarios, the complexity of operation and maintenance management and TCO. Users need innovativeness as well as enterprise-level block storage features to support VMware, Citrix, Oracle, Microsoft, K8s,etc.

Product Value

XEBS(XSKY Enterprise Block Storage)is a professional distributed block storage product offered by XSKY. Based on the "shared-nothing" architecture, it supports FC and iSCSI, and fully authenticates with AIX, Linux, Windows applications and enterprise-level virtualization technologies such as VMware and Citrix.


Professional APIs and Enhanced Reliability

  • Support a full range of IP-based iSCSI command words and the most widely used FC by professional storage devices
  • Redundant design of key IO paths and management control modules, supporting multi-path MPIO or VIP, active/active access, ensuring high system availability and fast switch
  • Support instant ROW snapshot, clone, async copy, automatic thin provisioning, LUN expansion and shrinkage on-the-fly, stretched cluster, cloud backup and other advanced enterprise-level features, adapting well to complicated scenarios and processes in enterprise storage management
  • Support settings on volume QoS. Users can set IOPS threshold value on volumes and performance burst limit to ensure consistent experience. Also support real-time modification on volume QoS, for dynamic allocation of performance resources, to deal with tidal scenarios.

Optimized Performance Based on Best Practices

  • Combined with mainstream NVMe flash technology and optimized IO path, a single node in XSKY cluster reaches tens of thousands of IOPS, providing highly-performed multi-level cache acceleration engine, including SSD two-level cache and RAM Read Cache with patented enhanced read-ahead algorithm to improve the read performance of system
  • SSD R/W Cache offers smart IO algorithm to greatly improve system R/W performance for OLTP
  • Interactive best practices based on various enterprise-level virtualization scenarios: VMware VAAI Ready, certified VMware Ready and Citrix Ready
  • XSKY best practices for container with certified CSI-iSCSI driver

Enhanced Easy-of-use and Manageability

  • Rich visual management functions and comprehensive management processes help users achieve rapid resource creation, installation, deployment and expansion, and enable users to easily control the complexity of distributed storage hardware
  • The tiered design of the fault domain and storage pool allows users to easily cope with resource planning and critical application partitions
  • Rich RESTful APIs, command line, SSD life prediction, S.M.A.R.T., operation log, system log and multi-level alert function help users quickly locate and solve emergencies in cluster

Typical Scenarios


Meet the unified storage demand of enterprise-level virtualization platforms including VMware ESXi, Microsoft Hyper-V and Citrix to simplify architecture and eliminate data islands.


Support the performance and capacity requirement of OLTP and OLAP database, reducing uneven distribution and building a flexible and in-control data resource pool.

Mainstream Container

Support of latest container ecosystem with certified CSI-iSCSI driver.

Hybrid Cloud

Connect private and public cloud to construct a hybrid cloud and support data backup from private cloud to public cloud on demand.
