Linode在国外VPS行业的一直都是领头羊的存在,有不少站长朋友戏称为主机行业“高富帅”,价格不低,但因其强悍的性能,还是有一批粉丝对此趋之若鹜。而对于性能方面,Linode也一直不曾停滞不前,目前正在全球11个数据中心推出超快、性能更好且更可靠的NVMe块存储。Linode也将从现在可用的亚特兰大机房开始,并在未来几个月内将NVMe扩展到Linode网络的其余部分。
块存储并不是免费的,费率将保持在每月0.10美元/GB。当NVMe块存储可用时,在Linode其他10个全球数据中心拥有现有卷的客户将能够迁移他们的卷。
NVMe是下一代SSD(固态设备)的硬件接口。该技术是对传统旋转硬盘驱动器的重大改进,吞吐量提高了10-20倍,IOPS提高了2000倍。借助NVMe支持的块存储,您可以体验数据库存储和其他任务的显著性能升级,在这些任务中,高存储速度和一致性至关重要。
此次全机群升级是Linode首次使用查处编码集群,这是一种在Ceph中存储数据的方法,该方法使用一种算法将数据切成块,从而显着提高了复制集群的存储效率。擦除编码允许我们从相同的原始磁盘容量中提取160%以上的可用存储。以一种使我们能够在不增加价格的情况下升级性能的方式实现了存储效率的惊人提高。
