Perchè dotarsi di un sistema Power con Linux

© 2014 International Business Machines Corporation

L’adozione di open-source software è una tendenza in crescita nel mercato. Le aziende stanno acquisendo competenze in ambito open-source e allo stesso tempo fanno leva su

contratti di supporto per progetti open-source. Linux è il sistema operativo strategico per supportare progetti open-source e per supportare le nuove

tipologie di workload: BigData & Analytics, Cognitive Computing. Le soluzioni open-source hanno trovato applicazione anche negli ambiti di virtualizzazione (KVM) e

Cloud Computing (OpenStack). L’Ecosistema di Sviluppatori, ISV, OEM, Community operanti nell’open-source si sta espandendo. IBM gioca un ruolo da protagonista nella contribuzione alla comunità Open-Source. IBM ha dichiarato nel settembre 2013 di voler investire 1 miliardo di dollari nell’innovazione dell’Open

Source per la piattaforma Power Systems (Linux, PowerKVM, Hadoop, OpenStack). Il culmine di questo intento all’investimento è stata la fondazione della comunità ‘OpenPower

Foundation’ (http://openpowerfoundation.org), una ‘open development community’ dedicata all’innovazione dei Data Center e delle soluzioni tecnologiche per supportare i nuovi workload: BigData & Analytics, Cloud Computing, etc.

Alla base della costituzione di questo consorzio c’è, per la prima volta nel mercato, un concetto di ‘openess’ dell’hardware e del systems software per l’innovazione collaborativa, basata su licenza per la ‘Power intellectual property’. Come risultato a tendere si avrà un rilancio su vasta scala della diffusione nel mercato della tecnologia Power.

Alla luce di queste considerazioni le due piattaforme Linux e Power Systems meritano un investimento di risorse e di competenze, così come intrapreso da IBM.

La piattaforma Linux on Power assume una valenza strategica per i nuovi workload, abbinando al sistema operativo Linux funzionalità e caratteristiche della nuova piattaforma POWER8, distintive rispetto alle piattaforme x86 in termini di prestazioni, scalabilità, virtualizzazione, affidabilità, sicurezza e resilienza.

http://openpowerfoundation.org/




Linux on Power (LoP) è una piattaforma che sta evolvendo in termini di disponibilità di applicazioni. Per quel che riguarda software IBM, è facilmente verificabile la compatibilità e il supporto delle applicazioni con LoP al seguente link esterno: ibm.biz/BdRvcB. Si ricorda che LoP beneficia di un licensing “agevolato” per prodotti IBM (PVU=70). Per quel che riguarda i software di altri ISV è possibile verificarne la disponibilità su LoP al seguente link: http://www.ibm.com/partnerworld/gsd/search.do.

A testimonianza dell’attenzione che gli ISV stanno rivolgendo alla piattaforma Linux on Power, SAP ha recentemente annunciato, in occasione dell’evento SAPPHIRE (4 giugno 2014), il programma di ‘Testing and Evaluation’ di SAP HANA su Piattaforma Power (Linux on Power).

Nel caso in cui le applicazioni non siano supportate su Linux on Power si deve considerare l’opportunità di intraprendere un percorso di migrazione.

Il porting delle applicazioni comporta un effort che varia in base alla loro tipologia: La maggior parte delle applicazioni Linux x86, che non presentano dipendenze dalla specifica

piattaforma, scritte con scripting o linguaggi di programmazione interpretati (Python, PHP, JavaScript, Perl etc), girano praticamente ‘as-is’ su Linux on Power.

La maggior parte delle applicazioni Linux x86, che non presentano dipendenze dalla specifica piattaforma, scritte in C++ non richiedono cambi del codice sorgente dell’applicazione, ma solo una ricompilazione.

Si stima che non piu’ del 5% delle applicazioni scritte in C++ per Linux x86 possa richiedere modifiche del codice sorgente.

Esistono tre categorie di risorse per la migrazione, per gli ISV: IBM PartnerWorld, per la comunità di sviluppatori: IBM developWorks, per i Clienti con applicazioni custom: Migration Factory.

Esistono Centri di Eccellenza (Innovation Center presso IBM Forum di Segrate, Montpellier, etc) disponibili a supportare POC, test e attività di migrazione.

Aapplicativi per il Linux on Power sono: Applicazioni ISV e Applicazioni Custom BigData & Analytics: Hadoop / IBM Infosphere BigInsights; Web Application Server (IBM WebSphere, JBoss Enterprise Application Server, TomCat) Web Server (Apache HTTP Server, Nginx, etc) SAP Application Server connessi a database DB2 oppure Oracle (Oracle Client 11.2 è in corso di

certificazione da parte di Oracle per LoP) SAP HANA on Power (‘Test and Evaluation Program’ on going) IBM DB2 LUW Open Source Database MariaDB (default database in RedHat EL7) and MySQL Community Server Open Source Database: EnterpriseDB / PostgreSQL Advance Server Ambiente di sviluppo Eclipse con tool specifici per LoP (analisi ed autocorrezione dell’endianess) Samba IBM GPFS Ubuntu 14.04 EL (little endian) come guest di PowerKVM.

Easy Tier Function Advantage

HDD SSDLow cost per IOPLow cost per GB

EasyEasyTierTier

Optional function with expanded-function, high-performance storage backplane

Automatically moves high activity (hot) data to SSD and low activity (cold) data to HDD

Function handled totally by POWER8 integrated SAS controllers. No application coding. No SAN, just internal SAS drives.

For AIX/Linux/VIOS. Just configure as a new type RAID array

IBM i already has hot/cold function in OS for all SAS adapters§Could use this function via VIOS (no performance data available at this time)§IBM i less automated, but has more controls/options


Controller Write Cache Value

Value depends on the amount/percentage of Writes

Valuable for SSD, even more valuable for HDD

Can even improve “reads” if application using recently written data still sitting in cache

SSD eMLC3 HDD (15k)

Graph is a simplification. All performance discussions start with the words “it depends”. HDD 15k Max ms shows typical maximum rotational delay and arm movement. 10k HDD is about 1 ms slower. Non-random work will have better HDD measurements. Actual HDD performance varies from HDD to HDD. Adapter write cache can also speed reads, but value of write cache for reads is highly application dependent. The bottom line (*) of the SSD is obtained when the DRAM write cache integrated into SSD can handle the write and with a low queue depth. The higher SSD value is with a higher queue depth and/or when the SSD write cache is not able to keep up with a stream of writes and the write is occurring to the NAND flash memory.
