This phase I trial studies the side effects and best dose of vorinostat when given together with fludarabine phosphate, clofarabine, and busulfan in treating patients with acute leukemia that is under control (remission) or has returned (relapse) undergoing donor stem cell transplant. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fludarabine phosphate, clofarabine, and busulfan, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving vorinostat together with fludarabine phosphate, clofarabine, and busulfan before a donor stem cell transplant may be a better treatment for patients with acute leukemia.

PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) of SAHA (vorinostat) in combination with the preparative regimen fludarabine (fludarabine phosphate), clofarabine, and busulfan followed by allogeneic hematopoietic stem cell transplantation (SCT) for patients with advanced acute leukemia.
SECONDARY OBJECTIVES:
I. To determine the rate of graft versus host disease (GVHD), engraftment, progression-free survival (PFS) and overall survival (OS) for this treatment regimen.
OUTLINE: This is a dose-escalation study of vorinostat.
CONDITIONING REGIMEN: Patients receive vorinostat orally (PO) once daily (QD), fludarabine phosphate intravenously (IV) over 1 hour, clofarabine IV over 1 hour, and busulfan IV over 3 hours on days -6 to -3. Patients receiving a transplant from a human leukocyte antigen (HLA)-matched unrelated donor, receive anti-thymocyte globulin IV over 4 hours on days -3 to -1.
TRANSPLANT: Patients undergo allogeneic peripheral blood stem cell or bone marrow transplant on day 0.
