Compute Engine now with 3 TB of high-speed Local SSD and 64 TB of Persistent Disk per VM
Monday, February 1, 2016
To help your business grow, we are significantly increasing size limits of all
Google Compute Engine
block storage products, including
Local SSD
and both types of
Persistent Disk
.
Now up to 64TB of Persistent Disk may be attached per VM for most machine types, including both Standard and SSD-backed Persistent Disk. The volume size limit has increased to 64 TB also, eliminating the need to stripe disks for larger volumes.
Persistent Disk provides fantastic price-performance and offers excellent usability for workloads that rely on durable block storage.
Persistent Disk SSD
delivers 30 IOPS per 1 GB provisioned, up to 15,000 IOPS per instance.
Persistent Disk Standard
is great value at $0.04 per GB-mo and provides 0.75 read IOPS per GB and 1.5 write IOPS per GB. Performance limits are set at an instance level, and can be achieved with just a single Persistent Disk.
We have also increased the amount of
Local SSD
that can be attached to a single virtual machine to 3 TB. Available in Beta today, you can attach twice as many partitions of Local SSD to Google Compute Engine instances. Up to eight 375 GB partitions or 3 TB of high IOPS SSD can now be attached to any machine with at least one virtual CPU.
We talked with Aaron Raddon, Founder and CTO at
Lytics
who tested our larger Local SSDs. He found they improved Cassandra performance by 50% and provide provisioning flexibility that can lead to additional savings.
The new, larger SSD has the same incredible IOPS performance we
announced
in January, topping out at 680,000 random 4K read IOPS and 360,000 random 4K write IOPS. With Local SSD you can achieve multiple millions of operations per second for
key-value stores
and a million writes per second using as few as 50 servers on
NoSQL databases
.
Local SSD retains the competitive pricing of $0.218 per GB/month while continuing to support extraordinary IOPS performance. As always, data stored in Local SSD is encrypted and our
live migration technology
means no downtime during maintenance. Local SSD also retains the flexibility of attaching to any instance type.
Siddharth Choudhuri, Principal Engineer at
Levyx
stated that doubling capacity on local SSDs with the same high IOPS is a game changer for businesses seeking low-latency and high throughput on large datasets. It enables them to index billions of objects on a single, denser node in real-time on Google Cloud Platform when paired with Levyx’s Helium data store.
To get started, head over to the
Compute Engine console
or read about
Persistent Disk
and
Local SSD
in the product documentation.
