ZStack云容灾解决方案,支持异构环境秒级备份和分钟级容灾

在这里插入图片描述

近日,ZStack新推出云容灾解决方案,不仅能实现ZStack Cloud平台的秒级CDP备份,高级模块还能支持物理机、虚拟化、私有云、公有云等多种场景在ZStack平台上进行容灾的需求,最低1秒的数据同步间隔、分钟级业务接管,为您的核心业务保驾护航。

容灾系统建设面临成本高、收益小等挑战

在传统的容灾系统建设中,为保证容灾系统能顺利完成业务接管,通常需要配置和生产环境匹配的性能资源和维护团队,保证容灾机房从物理性能到应用环境能与生产环境保持一致。这样往往使得容灾系统建设存在成本高、收益小等问题。往往是客户买了高价的保险,但到了硬件和应用更换周期可能并没有使用上。甚至在需要使用的时候,由于缺少数据一致性检查和应用环境已经不匹配等原因,无法完成接管任务。

如何确保灾难发生时能正常接管业务,如何充分发挥容灾机房平时“闲置”的性能资源,是目前容灾系统建设的主要挑战。

弹性+融合,ZStack云容灾解决方案

通过ZStack先进的容灾技术,充分利用云“弹性”与“融合”的特性,实现物理机、虚拟机、公有云和私有云等多业务场景的备份和容灾。方案支持将现有机房内生产业务系统云化为容灾云主机,并与生产业务实时同步。基于CDP技术的生产系统容灾保护,在任意一台被保护的服务器发生故障时,可实现分钟级的快速接管并恢复业务。

ZStack云容灾方案具备以下功能亮点:

1、异构支持:支持物理机、虚拟机、公有云、私有云、混合云架构;

2、秒级同步:支持秒级同步备份,智能重删复制,降低网络压力;

3、弹性容灾:按需弹性分配容灾所需资源,无容灾接管时无资源消耗;

4、多场景适配:支持应急接管、仿真测试、培训、云迁移等拓展场景;

5、可选时间接管:支持业务恢复到所需

Z-Stack 3.0.x is TI's Zigbee 3.0 compliant protocol suite for the CC2530, CC2531, and CC2538 Wireless MCU. Supports the CC2592 and CC2590 RF front ends which extend up to +22dBm and +14dBm transmit power, respectively, and provide improved receiver sensitivity Z-Stack 3.0 combines multiple previous Zigbee profiles into one unified standard Incorporates the unified Zigbee Cluster Library which is at the foundation of dotdot, the universal language for IoT applications defining data objects, models and functionalities for embedded IoT applications Implements Zigbee Base Device Behavior specification, which defines a common set of mechanisms for network forming, discovering, and application provisioning to be used by all Zigbee devices Based on Zigbee PRO 2015 stack, it provides new and improved security modes, including Install Codes for out-of-band key exchange, and Distributed Security Networks for Coordinator-less network topology Supports Green Power Proxy, allowing energy-harvesting and ultra-low power devices to connect seamlessly to a Zigbee network Forwards and backwards compatibility with previous Zigbee PRO and application profiles is maintained Sample Applications included for quick prototyping, including door lock, thermostat, light and switch, and temperature sensor Zigbee Network Processor firmware, providing an abstracted access to the Zigbee Pro 2015 stack and Base Device Behavior functionality via a serial port for two-chip architectures Zigbee-based applications Over-the-air firmware upgrade and serial bootloader capability, allowing for future updates of deployed systems Compatible with TI's Z-Stack Linux Gateway, a reference implementation of an Ethernet-to-Zigbee gateway using a Linux-based platform as host processor, that makes it easy to integrate applications on top of an IP-based interface which abstracts Zigbee protocol functionality to the users.
