Case study: Build Disaster-recovery from ordinary NAS almost free of charge

Today I will describe you the real situation from one huge IT environment.

Imagine that you spend million dollars from your budget. You build high-capacity NAS in your primary data center. You build the second one in your backup data center.

Besides the replication you have snapshots configured as well.

But do you have DR?

3 traditional problems of storage operation and non-traditional solution

Dream workflow
If you are managing storage operations team, you are dealing with task how to run systems within your limited budget. Every technical issue costs you a money.
Every outage caused by human error is therefore irritating.

To eliminate human errors you are fighting with 3 following issues:

  • not possible to limit admin access rights for less skilled team members
  • typos in the naming convention causing non-functional reports
  • non-unified configuration of disk arrays

Nobody is solving these problems in most of the companies as there is no time, willingness to do it and often there is a belief that the solution is extremely expensive.

But solution is relatively simple and surprisingly cheap.

3 tradičné problémy storage operations a ich netradičné riešenie

Dream workflow
Ak šéfuješ ľuďom, čo majú na starosti diskové polia, denne bojuješ s tým, ako zabezpečiť beh systémov v rámci svojho prideleného rozpočtu. Každý technický problém ťa stojí peniaze.
Každý výpadok spôsobený ľudskou chybou ťa štve o to viac.

A pri eliminácii ľudských chýb bojuješ s nasledovnými problémami:

  • Nemožnosť prideliť obmedzený admin prístup menej skúseným členom tímu
  • Neodhalené preklepy v názvosloví spôsobujú nefunkčnosť reportov
  • Nejednotná konfigurácia diskových polí

Vo väčšine firiem tieto problémy nikto nerieši. Nie je na to čas, chuť a často presvedčenie, že riešenie je extrémne drahé a tým pádom nie sú ani peniaze.

Riešenie je však relatívne jednoduché a prekvapivo lacné.
