EMC VNX Virtual Provisioning

One of the biggest challenges facing storage administrators is balancing how much space will be required by the various applications in their data centers. Typically, administrators are forced to allocate space based on projected storage growth.

But this often results in the overprovisioning of storage capacity, which then leads to higher costs; increased power, cooling, and floor space requirements; and lower capacity utilization rates. Even with careful planning, it may be necessary to provision additional storage in the future. This may require downtime depending on the operating systems involved.

Cuma apsal tak ramai bukan Melayu dalam gomen mungkin kerana beberapa perkara, antaranya policy pengambilan kakitangan, ata...
