Think GPFS POOLs ... Generally, you should not mix different kinds of LUNs into the same GPFS POOL.

The asymmetric SAN means, that not every LUN has the same speed, or not every disk array has the same number of LUNs. It seems that overal speed is degraded to the slowest LUN. Is there any workaround for this except avoiding that LUN at all? -- Lukáš Hejtmánek Linux Administrator only because Full Time Multitasking Ninja is not an official job title _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org https://urldefense.proofpoint.com/v2/url?u=http-3A__gpfsug.org_mailman_listinfo_gpfsug-2Ddiscuss&d=DwIFBA&c=jf_iaSHvJObTbx-siA1ZOg&r=cvpnBBH0j41aQy0RPiG2xRL_M8mTc1izuQD3_PmtjZ8&m=4g2oEvesNo0UZtsAeNzm33hQ9jYDALfLllZkZ2nMpak&s=aRp743C0EJjuap9PuF7U5CoPcqti2RRnGi6CwKojYtI&e=
