Top 5 Things I like about IBM DS3500 [IBM]

IBM created its successor to the DS3200/DS3300/DS3400 product line, the entry- level System Storage DS3500 Express. So, in order to give you a quick run-down of the best features and benefits of this new product, here’s my Top 5 list of things I like about this product:

1) It’s simple and all SAS

The DS3500 comes in only one model: SAS. And if you need to add things like Fibre Channel or iSCSI, no big deal, you just add the card. With it being all SAS, you are getting the best type of disk attachment. FATA didn’t work out too well, SCSI is getting old, and even SATA and FCAL will most likely give way to SAS too.

2) It’s got cost-effective backup and recovery

It provides investment protection and cost-effective backup and recovery with remote mirror across Fibre Channel so that you no longer need to buy something to put on top such as IBM SVC. It’s also compatible with existing DS4000s and DS5000s that you may already have in your business.   

The DS3500 can create two flashcopies without needing any extra licenses. So for example, if you are doing an application upgrade, you can give yourself a quick roll-back point by just reserving some space for a flashcopy repository.  [Read more…]

How the right server can save real $$ on application licensing [IBM]

Are application memory hogs eating up server space and causing licensing costs to go through the roof? If you answered “hell ya!” to that question you aren’t alone.

Until recently, the problem organizations have traditionally run into when virtualizing their data center environment has been the inability to scale server memory high enough to allow high density of virtual machines per server.

Virtualization and database applications are memory hogs. Typically, the user runs out of memory way before running out of processor power, especially with today’s extremely powerful Intel processors. And, to make matters worse, in the past the only way to scale memory to the max has been to fully populate the processor sockets. This has led to low virtual machine density and less than optimal desktop virtualization capability because of memory scalability limitations. It also means extremely high licensing costs for database applications since those costs are based on either processor count or socket count. [Read more…]
