g8i正式上线,具备超高性能、全方位安全防护两大特色优势。从关键性能参数上看,g8i实例全核睿频p0n达到3.2GHz,相比上一代实例,整机核密度提升50%,性能最大提升60%以上。网络标配阿里云自研eRDMA大规模加速能力,延时最低8微秒;存储方面全面搭载NVMe,支持共享盘,存储延迟低至百微秒。同时,g8i支持可信计算与加密计算等特性,默认内存加密(TME),并在全球范围率先支持TDX机密虚拟机能力。阿里云弹性计算产品线负责人张献涛表示,阿里云第八代企业级实例g8i的正式上线,标志着阿里云自研的CIPU架构及其最新特性eRDMA能力全面开始商业化,将大幅提升数据处理效率。阿里云CIPU+飞天的技术架构与第四代英特尔 至强可扩展处理器强强联合下,g8i规格族性能提升了60%,并进行机密虚拟机能力TDX在云上的首次实践,相信在双方的持续紧密合作之下,将会给更多各行业的客户带来更具性价比的技术红利。该实例采用“飞天+CIPU”技术架构,面向游戏、视频直播、电商、金融、医疗、企业服务等行业,满足其在数据库、大数据、AI 推理等应用场景下日益增长的性能需求。作为企业级实例,超高性能是g8i实例最为亮眼的优势,其中离不开阿里云自研CIPU:云数据中心专用处理器——为“飞天”操作系统设计的专用处理器。依托于CIPU+飞天的技术架构,g8i实例网络及存储I/O均实现大幅提升。CIPU具有业界首个大规模弹性RDMA加速能力,eRDMA与云上VPC共享同一张网络,用户可以随开随用具有eRDMA能力的实例;现有Redis、Spark、AI、HPC等应用,通过阿里云提供的接口,即可一键适配,最大程度的降低企业的使用难度。在AI深度学习场景,eRDMA能够提升大规模分布式NLP和视觉计算30%的训练性能;在Spark大数据场景,eRDMA能够提升10%的计算性能;在Redis KV数据库场景,eRDMA能够提升混合读写的100%的吞吐量。存储方面全面搭载NVMe,支持共享盘,存储延迟低至百微秒。NVMe云盘同时具备高可靠、高性能、以及丰富的企业特性。它基于NVMe标准协议打造,相比普通云盘具有更低的延迟和更高的吞吐,其基于NVMe协议实现的多实例挂载功能,也将极大方便企业高可用业务上云。NVMe云盘将逐步成为ECS云服务器主力云盘,并将持续围绕NVMe协议丰富特性和建设生态,为用户提供更多的价值。此外,第八代ECS实例在单核通用算力提升的基础上,还提供多种硬件原生加速能力,可以进一步提升应用性能。其中依托于AMX AI加速器,g8i深度学习训练场景性能提升2倍以上,推理性能提升4倍;QAT加速器则让加解密、压缩/解压缩等场景性能提升4倍以上;IAA加速器让RocksDB等数据存储工作负载性能相较于上一代提升1倍以上。作为亚太地区最早部署机密计算的云厂商,阿里云一直在持续推广可信与机密计算技术,以为客户的数据提供更好保护。ECS g8i实例全量搭载安全芯片TPM作为硬件可信根,在实例可信的基础上,配合英特尔硬件TEE能力和内存加密TME (IntelTotal Memory Encryption)技术,为大型互联网、新金融、医疗保健、知识产权等业务场景提供了更高安全等级数据保护能力。同时,阿里云联合英特尔启动了机密虚拟机TDX(Intel Trusted Domain Extension)的实践,实现了TDX技术全球范围内首发。阿里云认为,该技术将推动机密计算通用化和平民化,与可信技术一起,成为未来云上服务器的标准能力。","kind":null,"is_publish_news":null,"is_publish_highlight":null,"is_publish_live":null,"is_publish_wemedia":null,"editions":null,"symbols":[],"gpt_button":1},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0
