Google Cloud Z4M Storage-Optimized Machines Reach General Availability: Up to 168,000 GiB of Local SSD, 400 Gbps Cloud RDMA and 15.6 Million Random-Read IOPS
Google Cloud announced on November 7 that its next-generation storage-optimized Z4M machine series is now generally available in Google Compute Engine, offered as both virtual machines and bare-metal instances. Google said Z4M was built for super intelligence and machine learning training and inference workloads such as checkpointing, distributed key-value caches and parallel file systems, as well as business-critical databases.
Powered by fifth-generation Intel Xeon Scalable processors and Google's Titanium offload and storage technology, Z4M provides up to 168,000 GiB of local SSD storage coupled with up to 400 Gbps of Cloud RDMA networking, which Google said reduces data-access latency by up to 60% compared with TCP networking. Z4M VMs and bare-metal instances offer up to 192 vCPUs and up to 1,536 GiB of memory, with 875 GiB of local SSD per vCPU. Google said Z4M delivers up to 15.6 million random-read IOPS and up to 75,600 MiB/s of sequential-read throughput, improving on the previous Z3 series by up to 70% and 110% respectively.
For maintenance, Z4M VMs with 42,000 GiB or less of local SSD can be live-migrated, while larger VMs and bare-metal instances must be terminated and restarted with data preserved. Z4M also supports Hyperdisk block storage, with up to 512 TiB of network-attached capacity per instance. Among partner comments in the announcement, Nutanix vice president of product management Saveen Pakala said Nutanix Cloud Clusters (NC2) is coming to Z4M bare-metal instances; Silk chief R&D officer Adik Sokolovski said testing showed up to 3.7 times lower latency and up to 6 times lower CPU usage with Cloud RDMA over TCP; and WEKA chief product officer Ajay Singh said testing found roughly twice the read throughput and up to 79% more IOPS than the Z3 generation. Google said Z4M is available today in select regions worldwide, with regional availability confirmed through its sales team; the announcement listed no pricing.
