Capacity Planning
Disk space efficiency on NetApp storage arrays
Users of different storage arrays often wonder how much usable capacity they get out of purchased amount of disk shelfs. For sure this is a key metric in ROI and TCO calculations, this information is also essential to implement proper capacity planning. In an ideal world, we would probably purchase usable disk capacity directly from vendor, however we do not live in a ideal world so we need to think while making our storage purchases. In this article we will show, how much usable storage capacity we can get from physical disks with NetApp disk arrays, where are hiding overheads and how to influence these overheads.
Oracle over NFS on NetApp storage – 2 – Primary and DR site solution design
In today’s article, we will look again bit into deployment of Oracle DB over NFS protocol on NetApp storage. This article is based on practical experience with deployment of SAP using Oracle (10g) as a back-end as well as on experience with Oracle DB deployments (10g & 11g). Most parts of this article are from a documentation I have created for my last customer, who has been implementing DR solution between two sites with third site for Backup and Recovery. This article is a part of Oracle over NFS on NetApp series, during entire series, we will introduce you to our approach towards projects and as example we chose to give you deep insight into Oracle deployment which we are using as a show-case. In today’s second episode we will look into solution design, volume layout and how we hook it up to fit with our RPO and RTO described in article Oracle over NFS on NetApp storage – 1 – Analysis.
Efektivita diskového prostoru na diskových polích NetApp
Uživatele různých diskových polí často zajímá, kolik dostanou užitečné kapacity z určitého množství diskových shelfů. Zajisté se jedná o velice důležitý parametr jak pro výpočty TCO a ROI, stejně jako pro případné kapacitní plánování. V ideálním světě bychom od dodavatelů diskových polí kupovali použitelnou kapacitu, bohužel však v ideálním světě nežijeme a tak musíme při plánování kapacit přemýšlet. V tomto článku si tak ukážeme kolik použitelné kapacity se dá z fyzických disků vytěžit u diskových polí NetApp, kde všude se skrývají různé režijní ztráty a jaké parametry velikost těchto režijních ztrát mohou ovlivnit.
