Oracle Solaris & SPARC @ OOW17

There were a lot of rumors about Solaris and SPARC because Oracle fired around 1.500 HW developers some months ago. Around Oracle Open World were some product announcements and more information about Solaris. A brand-new SPARC chip came out and Oracle promised once again to invest into Solaris and give a Solaris 11 support at least until 2034.

They also mentioned the next Solaris 11.next release will come in fall 2017. So it will take some time to get 11.4 but hopefully with the  backport of Solaris 12 beta features since they canceled 12 in favor of 11.next.

Oracle SPARC M8 Processor

The new SPARC CPU has 32 cores again but at 5 GHz based on a new 20nm core design with “Software in Silicon v2”.  We have now four execution pipelines, they doubled the size of L1 cache and increased the performance of the DAX engines (1.8 vs. 2.2 GHz). M8 comes with 180 GB/s memory bandwidth measured, and a raw memory links performance of 374 GB/s per processor. (BTW; did you know that the latest Xeon 8180M launched at Q3’17 only provides 119 GB/s). We got Oracle number acceleration units and SHA-3 was added to the other 15 cyphers and hashes we had in M7 cryptography co-processors.

Compared to M7 that is a 1.5x better single-thread performance with 21% higher frequency and on the memory site 16% higher bandwidth but with still 6% lower memory latency. That’s a very nice and easy improvement for your Solaris installations. And do not forget, just migrate your LDOM live to the new M8 server and enjoy the faster environment…

Oracle says:

SPARC M8 processors running Oracle Solaris 11.3 ran 2.9 times faster executing AES-CFB 256-bit key encryption (in cache) than the Intel Xeon Processor Platinum 8168 (with AES-NI) running Oracle Linux 7.3.

SPARC M8 processors running Oracle Solaris 11.3 ran 6.4 times faster executing AES-CFB 256-bit key encryption (in cache) than the Intel Xeon Processor E5-2699 v4 (with AES-NI) running Oracle Linux 7.2

Oracle Fujitsu SPARC XII

Also Fujitsu announced a new Sparc64 processor called SPARC XII which can be bought as OEM from Oracle. A 12 core CPU @ 4,25 GHz in systems with 1 to 32 sockets and up to 32 TB memory.

 

 

Oracle X7 Server

With the latest x86 generation you will also get Support and the RTU for Solaris-x86. Oracle X7 Server comes with 1 up to 8 Sockets with 192 cores and 6 TB memory.

Overall great news for your Solaris investments and big datacenter irons 🙂

 

 

 

Solaris FMD logs

How to clear fmadm log or FMA faults log

(based on FMA Cheat Sheet (Doc ID 1355350.1))

Had some issues in the last days getting my "fmadm faulty" empty... standard commands did not work 

# fmadm repair <UUID>
# fmadm clear <UUID>
# fmadm acquit <UUID>

I had to delete FMDs "database" files: 

# svcadm disable -s svc:/system/fmd:default
# cd /var/fm/fmd
# find /var/fm/fmd -type f -exec ls {} \;
# find /var/fm/fmd -type f -exec rm {} \;
# svcadm enable svc:/system/fmd:default
# fmadm reset cpumem-diagnosis
# fmadm reset cpumem-retire
# fmadm reset eft
# fmadm reset io-retire
# fmadm faulty
<empty output again>

SPARC Console

Primary Domain logs to SP 

-> set /SP/console line_count=1000
-> show /SP/console/history

Console I/O from all other domains is redirected �to virtual console concentrator (vcc) 

# tail /var/log/vntsd/<ldom>/console-log[.<num>]

Console logging is enabled by default 

# ldm list -o console ldomsc0
NAME
ldomsc0

VCONS
    NAME         SERVICE                PORT   LOGGING
    ldomsc0      primary-vcc@primary    5002   on

Domain must be in an inactive and unbound state before changing 

# ldm set-vcons log=off <ldom>

!! Older than Oracle Solaris 11.1 cannot be logged !!
