BM 最近开始交付其新一代 Power Systems 服务器,该服务器采用了其新设计的 POWER9 处理器。这些基于 POWER9
的横向扩展系统,包括 S914、S922、S924、H922、H924 和
L922,在内存数据库、高级分析和云环境等非加速计算空间中提供领先能力。

POWER9 横向扩展服务器是云就绪的,包括内置的 PowerVM 虚拟化功能,使您能够部署云环境以满足组织不断变化的业务需求。适用于 IBM i、AIX 和 Linux 的 POWER9 横向扩展服务器可轻松集成到您组织的云和 AI 战略中,同时提供 Db2 和 Oracle 等任务关键型工作负载所需的性能和 RAS。IBM 还提供专为 SAP HANA® 构建和优化的 POWER9 横向扩展服务器,在 2U 外形尺寸中拥有高达 4TB 的内存占用,可以更快地获得洞察力,同时提供卓越的可靠性和性能。

这些新系统采用了我们最新的 I/O 技术,包括用于 CAPI 和 OpenCAPI 的 25 GB/秒高速互连以及嵌入式 PCI-Express 4.0 连接,与 PCI-Express 3.0 [1]相比,I/O 带宽增加了一倍。

POWER9 2 插槽系统提供高达 4TB 的内存,比 Intel x86 Xeon 系统[2]多出 33% ,为 SAP HANA 等内存数据库提供了额外的优势。

POWER9 延续了前几代产品的传统,与前代产品相比,提供了改进的单核性能。与类似的 POWER8 系统相比,POWER9 提供每核 1.25-1.5 倍的性能能力,使客户能够进一步减少按核许可的堆栈上的软件支出[3]。与 x86 系统相比,这种对核心架构和功能的关注在广泛的基准测试[4]中提供了超过 2 倍的每核性能。

重点不仅在于性能,还以降低成本的形式为客户提供价值。在数据库和高级分析环境(如 Db2 Warehouse [5])中,L922 的性价比是 Intel x86 系统的 2.4 倍。

在云环境中,这些系统利用卓越的核心性能和内存带宽来提供性能和性价比优势;例如,在应用服务器领域,它们提供了比 x86 2-socket 系统高 3.4 倍的核心性能和 2.4 倍的性价比。[6]
