Az el\u0151z\u0151 cikk\u00fcnkben arr\u00f3l \u00edrtunk, hogyan optimaliz\u00e1lhatjuk a Zimbra levelez\u00e9si t\u00e1rol\u00f3kat, hogy a lehet\u0151 legjobb teljes\u00edtm\u00e9nyt ny\u00fajts\u00e1k. A Zimbra Collaboration Suite Open-Source Edition adminisztr\u00e1tor\u00e1nak m\u00e1r az infrastrukt\u00fara tervez\u00e9s\u00e9nek korai szakasz\u00e1ban meg kell hat\u00e1roznia a levelez\u00e9si t\u00e1rol\u00f3k m\u00e9ret\u00e9t. Az egyik aj\u00e1nl\u00e1s az volt, hogy alaposan m\u00e9rlegelj\u00fck az inode-okhoz tartoz\u00f3 byte-ok sz\u00e1m\u00e1nak kiv\u00e1laszt\u00e1s\u00e1t, amelyeket a mke2fs seg\u00e9dprogram \u00e1ll\u00edt el\u0151 a merevlemezeken, valamint a -i param\u00e9tert a f\u00e1jlrendszer l\u00e9trehoz\u00e1sakor.<\/p>\n

Ahhoz azonban, hogy pontosan meghat\u00e1rozhassuk az \u00e1tlagos \u00fczenetm\u00e9retet a tervez\u00e9s szakasz\u00e1ban, a rendszergazd\u00e1nak meg kell b\u00edrnia a pr\u00f3f\u00e9tai aj\u00e1nd\u00e9kat.

A Zimbra administrator can benefit from the Zextras PowerStore extension, which, thanks to its Hierarchical Media Management feature, allows connecting an additional storage device and thus postponing decisions about average message size and data volume until adequate statistics are available.<\/p>\n

3. Possibility to avoid using LVM<\/b><\/p>\n

Logical Volume Manager, although an excellent solution that seems well-suited for Zimbra's email storage due to its expansion capabilities and snapshot management, has a number of drawbacks. Key among these are the more complex management of volumes compared to standard disks and the high risk of the entire LVM failing if one physical device is damaged, which is quite critical in large-scale Zimbra installations.<\/p>\n

Zextras PowerStore, on the other hand, allows for the avoidance of using LVM and offers the ability to expand available capacity by connecting standard hard drives. This enables Zimbra administrators to simplify storage management as much as possible, while optimizing the backup process and thereby making the entire infrastructure more fault-tolerant.<\/p>\n

2. Ability to move data to other volumes and storage devices<\/b><\/p>\n

It is always better to prevent a problem than to deal with its consequences later. This rule certainly applies to situations like hard drive failures and the associated complete or partial data loss. Scheduled replacement of information storage devices is a common practice among SaaS providers, who find it easier to plan a maintenance pause and inform clients in advance than to suffer losses and damage their image due to an unexpectedly failed hard drive.<\/p>\n
