Performance Comparison SPARC T4 and SPARC S7

SPARC S7
JomaSoft replaces the SPARC T4-1 Server with the new SPARC S7-2 Server (with 2 sockets / 8 cores each at 4.26Ghz).

Read more about the SPARC S7-2 Server

Comparison
We created a 3GB / 1 core LDom on our SPARC T4-1 Server running Solaris 11.3 SRU11 with all data stored on a SAN Disk. Inside the LDom we installed our VDCF application and loaded datacenter configuration into the VDCF sqlite database. Next we executed datacenter analysis like patch comparison, calculated migration possibilities and server configuration consistency checks. The analysis are traditional single thread workload.

After the tests on the SPARC T4-1 we migrated our LDom to the new SPARC S7-2 Server. This allowed us to compare the systems using the same Operating System, Setup and Data, to make sure we compare “apple to apple”.

The results for our workload showed a 2x faster performance on the SPARC S7-2 Server. We are very happy with this results. This workload did not use the Software In Silicon features, only performed better because of the new CPU architecture (higher frequency, more and better CPU cache and memory).

In my view the SPARC S7-2 Server is the ideal platform for customers to replace their old SPARC hardware with an excellent price / performance ratio.

How to change Solaris Zones configurations online

I assume you are aware that Solaris Zones are one of the most valuable features of Solaris since years. In this post I focus on the "Live Zone Reconfiguration" feature available since
Solaris 11.2 for Solaris Zones and since Solaris 11.3 for Kernel Zones. CPU pools, filesystems, network and disk configurations can be changed while Solaris Zones are running.

1. Limit CPU usage of a Solaris Zone using dedicated-cpu

By default Solaris Zones share the CPUs with the global and all other local Zones.
Our sample Zone currently uses 16 virtual CPUs.

# zlogin v0131 psrinfo | wc -l

16


We can now assign 4 dedicated virtual CPUs to be used by this Zone only.

# zonecfg -z v0131 -r "add dedicated-cpu; set ncpus=4; end"

zone 'v0131': Checking: Adding dedicated-cpu

zone 'v0131': Applying the changes

# zlogin v0131 psrinfo | wc -l

4
The “zonecfg -r” changes the configuration of the running Zone only.
Make sure to run the command once again to make the configuration persistent for the next Zone reboot.

# zonecfg -z v0131 "add dedicated-cpu; set ncpus=4; end"


2. Create and mount an additional ZFS filesystem

# zfs create v0131_data/myapp

# zonecfg -z v0131 -r "add fs; set type=zfs; set dir=/myapp; set special=v0131_data/myapp; end"

zone 'v0131': Checking: Mounting fs dir=/myapp

zone 'v0131': Applying the changes


# zlogin v0131 mount | grep myapp

/myapp on /myapp read/write/setuid/devices/rstchown/nonbmand/exec/xattr/atime/zone=v0131/nozonemod/sharezone=4/dev=d50045 on Fri Jun 10 11:56:19 2016


And make it persistent

# zonecfg -z v0131 "add fs; set type=zfs; set dir=/myapp; set special=v0131_data/myapp; end"

Adding network interfaces and disk devices are similar to the samples above.

Upgrade 10 SPARC LDoms to Oracle Solaris 11.3 in 20 Minutes

Basics first
Oracle Solaris 11 includes a powerful Upgrade Feature based on IPS (Image Packaging System)
and ZFS. When Upgrading the Operating System a new Boot Environment is created and updated.
No impact on the currently running System. The new Environment is activated using a reboot. This allows to failback to the old Boot Environment if Applications don't run as expected on the new Solaris Release.

Find more about Upgrading in the Oracle Solaris 11.3 Manual
https://docs.oracle.com/cd/E53394_01/html/E54739/pkgupdate.html#scrolltoc

Upgrading using VDCF
The VDCF Management Framework for Oracle Solaris includes a feature to upgrade multiple Nodes in parallel using one command. The operation to use is "node -c upgrade name=nodeA,nodeB build=targetSRU". This upgrade operation does not only upgrade the OS to a predefined build, it also first checks if enough disk space is available. After a successful OS Upgrade the VDCF Repository is updated with the new Boot Environment and OS Update.

Sample of Upgrading 10 LDoms in parallel
The VDCF Framework is installed in a small LDom running on a SPARC T4-1 Server. The 10 Target LDoms are running Solaris 11.2 on a SPARC T4-2 System. Some of the LDoms host Solaris Zones,
which are also upgraded in parallel.



VDCF uses the Oracle Solaris pkg command with the following options
-C 5                                 to update the Zones in parallel
--be-name s11.3.3.0.6.0              to set a meaningful BootEnv Name
entire@0.5.11,5.11-0.175.3.3.0.6.0   to select a specific Solaris SRU


Upgrade Output
-bash-4.1$ time node -c upgrade reboot force build=s11u3-sru3 name=g0042,g0068,g0070,g0084,g0092,g0095,g0096,g0097,g0102,g0103

Summary
This blog post shows how to Upgrade multiple Oracle Solaris LDoms to Solaris 11.3.
Using the VDCF Management Framework 10 SPARC LDoms are done in 20 Minutes.
The T4-Hardware is 4 years old. Just imagine how fast such Upgrades will run on the current SPARC M7 Systems!

JomaSoft's Performance Results on #SPARC T7 Server

SPARC M7
Oracle announced the 32 Cores 4.13Ghz #SPARC M7 Processor with Software in Silicon features and T7 and M7 Servers at Oracle OpenWorld.

You can find details in Masood Heydari's Presentation at Oracle OpenWorld


Summary
We @JomaSoft recently completed performance tests on Oracle’s SPARC T7 system running Virtual Datacenter Control Framework (#VDCF), our management solution for creating, migrating, patching and monitoring Oracle Solaris environments. Our results showed VDCF to be 1.5x faster core-to-core on SPARC T7 compared to SPARC T5. JomaSoft views Oracle’s powerful SPARC M7 and T7 systems as ideal platforms for customer consolidation and virtualization projects, with technology and value that no other vendor can offer.

Technical details
We created a 8GB / 1 core LDom on a SPARC T5 Server running Solaris 11.3 with all data stored on a SAN Disk. Inside the LDom we installed our VDCF application and loaded datacenter configuration into the VDCF sqlite database. Next we executed datacenter analysis like patch comparison, calculated migration possibilities and server configuration consistency checks. The analysis are traditional single thread workload.

After the SPARC T5 tests we migrated our LDom to the new SPARC T7 Server. This allowed us to compare the systems using the same Operating System, Setup and Data, to make sure we compare “apple to apple”.

The results for our workload showed a 1.5x faster performance on the SPARC T7 Server. This workload did not use the Software In Silicon features, only performed better because of the new CPU architecture (higher frequency, more and better CPU cache and memory).

The Software In Silicon features can be used to optimize SQL and crypto functions when running applications In-Memory on the Oracle Database 12c. Performance increase of 80x or more are possible.

#VDCF Release 5.6 for @Oracle #Solaris 11.3

After Solaris 11.3 is available from Oracle, we released the Version 5.6 of VDCF today.
VDCF is a Command Line based Management Tool for Oracle Solaris. It provides a higher level API for System Administators.
Makes Deployment, Management, Migration, Failover and Monitoring of Solaris, LDoms and Zones
much easier and faster. You don't need deep knowledge of Solaris to use it.
VDCF is already verified on the new #SPARC M7.

New major Features
- Support of Solaris 11.3 und LDom 3.3
- Root IO Domain Discovery and Split IO GDom Deploy
- OS Monitoring for Dataset/ZPOOL and SMF Services

Btw VDCF is a Swiss quality Software and very stable product. Version 1.0 was released 2006!

There is a free trial version available.
